ITEM 1.  FINANCIAL STATEMENTS (Unaudited)




                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders of Sonex Research, Inc.

We have reviewed the condensed financial statements appearing on pages 3 through
12 of this Form 10Q-SB Quarterly Report of Sonex Research,  Inc. (the "Company")
as of March 31, 2002. These financial  statements are the  responsibility of the
Company's management.

We conducted our review in accordance with standards established by the American
Institute  of  Certified  Public  Accountants.  A review  of  interim  financial
information consists principally of applying analytical  procedures to financial
data and making  inquiries of persons  responsible  for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with  generally  accepted  auditing  standards,  the  objective  of which is the
expression of an opinion  regarding the financial  statements  taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material  modifications that should
be made to the  accompanying  financial  statements for them to be in conformity
with generally accepted accounting principles.

We previously audited, in accordance with generally accepted auditing standards,
the balance  sheet as of  December  31,  2001,  and the  related  statements  of
operations and  accumulated  deficit and cash flows for the year then ended (the
"audited financial  statements",  not presented herein), and in our report dated
April  10,  2002,  we  expressed  an  unqualified  opinion  on  those  financial
statements.  We also stated that the audited financial  statements were prepared
assuming  that  the  Company  will  continue  as a going  concern;  however,  as
described  in  Note 3 to the  audited  financial  statements,  the  Company  has
incurred  significant net losses since its inception and its ability to commence
generation of significant  revenue and ultimately achieve profitable  operations
raise  substantial  doubt  about the  Company's  ability to  continue as a going
concern.  The  audited  financial  statements  and  the  accompanying  condensed
financial  statements do not include any adjustments  that might result from the
outcome of this uncertainty.

                              SONEX RESEARCH, INC
                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (Unaudited)


NOTE 1 - THE COMPANY

Sonex Research, Inc. has developed a proprietary technology,  known as the Sonex
Combustion  System  (SCS),  which  improves the  combustion  of fuel in internal
combustion  engines through  modification of the pistons in large engines or the
cylinder  heads  in small  engines.  The SCS  achieves  in-cylinder  control  of
ignition and  combustion  to increase fuel mileage of gasoline  engines,  reduce
emissions of diesel engines,  and permit small gasoline  engines to run on safer
diesel-type  fuels. The Company's  objective is to execute broad agreements with
engine and parts manufacturers for industrial production of SCS components under
license from Sonex.


NOTE 2 - PRESENTATION OF FINANCIAL STATEMENTS

The accompanying  unaudited condensed financial statements have been prepared in
accordance with generally accepted  accounting  principles for interim financial
information  and  with the  instructions  to Form  10-QSB  and  Item  310(b)  of
Regulation S-B.  Accordingly,  these financial  statements do not include all of
the  information  and  footnotes  required  by  generally  accepted   accounting
principles for complete financial statements. In the opinion of management,  all
adjustments (consisting of normal recurring accruals) considered necessary for a
fair presentation have been included.

Operating  results  for the three  month  period  ended  March 31,  2002 are not
necessarily  indicative  of the results that may be expected for the year ending
December 31, 2002. For further  information,  reference is made to the financial
statements  and notes thereto  included in the  Company's  Annual Report on Form
10-KSB for the year ended December 31, 2001.


NOTE 3 - LIQUIDITY

Management  recognizes that the Company's history of operating losses,  level of
available funds, and revenue from current and future development  contracts,  in
relation to projected expenditures,  raise substantial doubt as to the Company's
ability   to   commence   generation   of   significant    revenues   from   the
commercialization  of the  SCS and  ultimately  achieve  profitable  operations.
Accordingly,  the Company will continue to minimize its  operating  expenditures
through a number of measures,  including the continued  deferral by its officers
of portions of their salaries.

As further  described in Note 6, in a private placement at the end of March 2002
the Company raised capital of $60,000,  including  $27,000 in cash  investments,
$27,000 from the conversion to equity of accrued liabilities,  and cash proceeds
of $6,000 through the issuance of a short-term convertible note. Also at the end
of March 2002, the Company  received a purchase order of  approximately  $92,000
from a defense  contractor for a four-month effort to develop a small heavy fuel
engine for an experimental unmanned aerial vehicle.

Based upon  available  resources,  current and projected  spending  levels,  and
expected revenue from current and anticipated contracts, management believes the
Company will have sufficient  capital to fund operations  through June 30, 2002.
The Company's prospects beyond that date are dependent upon its ability to enter
into  significant  funded  contracts  for  the  further  development  of its SCS
technology,  establish  joint  ventures  or  strategic  partnerships  with major
industrial concerns,  or secure a major capital infusion.  There is no assurance
that the Company will be able to achieve these objectives.


NOTE 4 - PATENTS

The  costs  associated  with the  filing of patent  applications  are  deferred.
Amortization is recorded on a straight-line  basis over the remaining legal life
of patents, commencing in the year in which the patent is granted. Costs related
to patent applications which ultimately fail to result in the grant of a patent,
as well as the unamortized costs of patents abandoned by the Company due to lack
of expected  commercial  potential,  are charged to  operations at the time such
determination is made.


NOTE 5 - ACCRUED COMPENSATION AND BENEFITS

Accrued  compensation  consists  of the  following  amounts  payable  to current
employees:

                                          March 31,          December 31,
                                            2002                 2001
                                       --------------       --------------

   Accrued vacation pay                $       55,675       $       58,000
   Accrued bonuses                             60,500               83,000
   Accrued wages                              129,380               80,228
                                       --------------       --------------

                                       $      245,555       $      221,228
                                       ==============       ==============


The Company's only liability to employees for future compensated absences is for
accrued but unused  vacation pay. The amount of vacation pay earned by employees
is  determined  by job  classification  and length of service.  Such amounts are
payable upon  termination  of employment and are not subject to the terms of the
Company's  written  agreement with current and former employees to defer payment
of portions  of their  salaries  as  described  in Note 6. The amount of accrued
vacation included above that was payable to the Company's  officers at March 31,
2002 and December 31, 2001 was $40,213 and $41,406, respectively.

In December of each of the last three years,  the Company awarded bonuses to its
officers and employees with the  stipulation  that payment of such bonuses is to
be deferred  until the Board of Directors  determines  that the  Company's  cash
resources are sufficient to enable such  payments.  In December 2001 the Company
awarded bonuses totaling  $57,500,  including an aggregate of $50,000 to its two
officers.  During 2001 the Company paid $12,500 of the bonuses accrued as of the
previous  year-end,  portions of which  payments  represented  the conversion of
accrued bonuses to equity.  In connection with a private placement at the end of
March 2002, the Company paid $22,500 of accrued  bonuses  through the conversion
of such amounts to equity.

Since early 2001,  the  Company's  officers  have  voluntarily  and at their own
discretion deferred receipt of payment of significant  portions of their current
wages to reduce the Company's monthly cash  requirements.  Such wages payable to
the Company's  officers  totaling  $113,710 are included in the total of accrued
wages as of March 31,2002.  The continued  deferral of portions of current wages
by the Company's officers cannot be expected to continue  indefinitely,  and the
Company will be required to pay such accrued wages as soon as cash flow permits.
The amount and timing of such payments  will be determined at the  discretion of
the Company's  officers,  as these accrued wages are not subject to the terms of
the  Company's  written  agreement  with  current and former  employees to defer
payment of portions of their salaries as described in Note 6.


NOTE 6 - DEFERRED COMPENSATION

In order to help conserve the Company's  limited cash  resources,  the Company's
officers and certain of employees  for several years have  voluntarily  deferred
receipt of payment of significant  portions of their authorized  annual salaries
at the request of the Board of Directors. By written agreement with the Company,
these  individuals  have  consented  to the  deferral  of  payment of amounts so
accumulated  until the Company  has  received  licensing  revenue of at least $2
million or at such earlier date as the Board of  Directors  determines  that the
Company's cash flow is sufficient to allow such payment.

Deferred compensation outstanding is payable to the following classifications of
personnel:


                                                March 31,        December 31,
                                                  2002               2001
                                             --------------     --------------

    Current officers                         $      538,018     $      525,337
    Current employees and consultants                62,088             62,088
    Former officers and other employees             270,519            270,519
                                             --------------     --------------

                                             $      870,625     $      857,944
                                             ==============     ==============


The  conditions  that would  require  repayment of deferred  amounts have yet to
occur,  and it is unlikely  that such  conditions  will occur prior to March 31,
2003.  Accordingly,  such deferred  compensation  is reported  separately in the
accompanying balance sheet as a non-current liability.

At the  conclusion  of a legal  challenge by two former  officers of the Company
initiated  in  1993  demanding  full  payment  of  deferred  salaries  upon  the
termination of their  employment,  in 1996 the Maryland Court of Special Appeals
rejected this demand and ruled that the written agreement to defer  compensation
was a valid and enforceable contract.


NOTE 7 - INCOME TAXES

The  Company  has not  incurred  any  federal or state  income  taxes  since its
inception  due to operating  losses.  At December 31, 2001,  the Company had net
operating loss and capital loss  carryforwards  of  approximately  $14.2 million
available to offset future taxable income. If certain substantial changes in the
Company's  ownership  should occur,  there would be an annual  limitation on the
amount of the carryforwards which can be utilized. Since 1995 net operating loss
carryforwards  aggregating  $4,781,634 have expired unused, as have capital loss
carryforwards of $201,681.


NOTE 8 - STOCKHOLDERS' EQUITY

Authorized capital stock

The Company is presently authorized to issue 48 million shares of $.01 par value
common stock and 2 million shares of $.01 par value convertible preferred stock.
All of the  authorized  shares of  preferred  stock,  along  with  common  stock
purchase  warrants,  were issued for $2 million in February 1992 (the "Preferred
Stock Investment") to a small number of individuals who qualified as "accredited
investors"  pursuant to Rule 501 of Regulation D of the  Securities  Act of 1933
(the  "Act") and to  Proactive  Partners,  L.P.  and  certain of its  affiliates
("Proactive"),  who became the largest  beneficial owner of the Company's common
stock by virtue of the acquisition of the convertible preferred stock and common
stock purchase warrants.

The preferred  stock has priority in liquidation  over the common stock,  but it
carries no stated  dividend.  The holders of the  preferred  stock,  voting as a
separate class,  have the right to elect that number of directors of the Company
which  represents a majority of the total  number of  directors.  The  preferred
stock is  convertible  at any time at the option of the holder into common stock
at the rate of $.35 per share of common stock.  As of March 31, 2002, a total of
459,999 shares of preferred  stock had been  converted into 1,314,278  shares of
common stock.


Private placements of common equity

In a private  placement at the end of March 2002,  the Company raised capital of
$60,000,  including $27,000 in cash investments,  $27,000 from the conversion to
equity of accrued liabilities to officers,  employees and consultants,  and cash
proceeds of $6,000 through the issuance of a short-term note that is convertible
to  equity  at the  option  of the  holder.  A total of  360,000  shares  of the
Company's common stock and five-year  warrants to purchase an additional 180,000
shares of common  stock at $.25 per share  were  issued in this  financing,  and
60,000 shares were reserved for future  issuance upon the conversion of the note
payable to common stock and a warrant to purchase common stock.

The offer and sale of these  shares of common  stock and  warrants  to  purchase
shares of common stock  satisfied the  conditions of Rule 506 of Regulation D of
the Act and, as such, were exempt from the registration  requirements of Section
5 of the Act as  transactions  not  involving  any  public  offering  within the
meaning of Section 4(2) of the Act.


Stock options

The Company  maintains a non-qualified  stock option plan (the "Plan") which has
made available for issuance a total of 7.5 million  shares of common stock.  All
directors,  full-time  employees and consultants to the Company are eligible for
participation.  Option awards are  determined at the  discretion of the Board of
Directors.  Upon a change in control of the  Company,  all  outstanding  options
granted to employees and  directors  become vested with respect to those options
which have not  already  vested.  Options  outstanding  expire at various  dates
through March 2012.

The Company  accounts for  stock-based  compensation  using the intrinsic  value
method prescribed in Accounting Principles Board (APB) Opinion No. 25. Under APB
No. 25,  compensation  cost is  measured  as the  excess,  if any, of the quoted
market price of the Company's stock at the date of grant over the exercise price
of the  option  granted.  Compensation  cost  for  stock  options,  if  any,  is
recognized  ratably over the vesting period.  In its complete  annual  financial
statements  presented in its Form 10-KSB,  the Company  provides  additional pro
forma disclosures as required under Statement of Financial  Accounting Standards
No. 123 - "Accounting for Stock-Based  Compensation"  as if the fair value based
method of accounting had been applied to the Company's stock option grants.

From  January 1, 2002  through  March 31,  2002,  the Company had the  following
activity in options to purchase shares of common stock under the Plan:

Common stock reserved for future issuance

At March 31, 2002, a total of 11,516,832 shares of common stock were reserved by
the Company for issuance for the following purposes:

NOTE 9 - COMMITMENTS

The Company  occupies  its office and  laboratory  facility on a  month-to-month
basis  under the terms of an  operating  lease  agreement  pursuant to which the
property owner is required to provide thirty days notice if he wants the Company
to vacate the premises.  The lease currently provides for monthly rent of $4,000
and requires the Company to pay all property related expenses.  The Company will
seek to  negotiate  a new  long-term  lease for its  facility  or search  for an
alternative  location in the event that a long-term  agreement cannot be reached
for the  existing  premises.  Management  believes  that the  resolution  of the
uncertainty  with  respect  to the  facility  will not  result in a  significant
interruption in the operations of the Company.




ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL POSITION
                         AND RESULTS OF OPERATIONS



Caution regarding forward-looking statements

Sections of this document,  as well as all publicly  disseminated material about
Sonex Research, Inc. (the "Company" or "Sonex"), contain information in the form
of  "forward-looking"  statements  within the meaning of the Private  Securities
Litigation  Act of 1995  (the  "Act").  Such  statements  are  based on  current
expectations,  estimates, projections and assumptions by management with respect
to, among other things,  trends affecting the Company's  financial  condition or
results of operations  and the impact of  competition.  Words such as "expects",
"anticipates",  "plans", "believes",  "estimates", variations of such words, and
similar  expressions are intended to identify such statements that include,  but
are not limited to, projections of revenues,  earnings,  cash flows and contract
awards. Such forward-looking statements are not guarantees of future performance
and involve risks and  uncertainties,  all of which are difficult to predict and
many of which are beyond the control of the Company.


Risk factors

In order to obtain the benefits of the "safe  harbor"  provisions of the Act for
any  such  forward-looking   statements,   the  Company  cautions  shareholders,
investors and prospective investors about significant factors which, among other
things,  have in some cases affected the Company's actual results and are in the
future  likely to affect the Company's  actual  results and cause them to differ
materially from those expressed in any such forward-looking statements.

Factors  that could  cause  actual  results  to differ  materially  include  the
specific risks listed below. These risks and uncertainties are not the only ones
faced by the Company or that may adversely  affect its  business.  If any of the
following  risks  or  uncertainties  actually  occur,  the  Company's  business,
financial  condition  or results of  operations  could be  materially  adversely
affected.

      o    ability to generate cash flow from revenue or to secure financing
           necessary to fund future operations
      o    ability to demonstrate commercial viability of its technology
      o    ability to complete technology development and demonstration programs
           and execute licensing agreements that produce significant revenue
      o    ability to maintain and protect its patents
      o    ability to attract and retain skilled personnel
      o    changes in general economic conditions
      o    competition

Furthermore,  since its inception in 1980, the Company has generated  cumulative
net losses in excess of $22 million,  and is likely to incur quarterly operating
losses for the  foreseeable  future.  The business has not generated  sufficient
cash flow to fund operations  without  resorting to external sources of capital.
In the event that funding from  internal and external  sources is  insufficient,
the Company would have to cut back  significantly  its level of spending,  which
could  substantially  curtail the Company's  operations.  These reductions could
have an adverse effect on the Company's relations with its potential customers.

The Company's success also depends in significant part on the continued services
of its key technical  and senior  management  personnel.  Losing one or more key
employees,  including for reasons of poor health,  disability,  or death,  could
have a material adverse effect on the Company's business, results of operations,
and  financial  condition.  Due to the expense  involved,  the Company  does not
maintain life  insurance  policies for any of its  employees.  Additionally,  in
order  to avoid  long-term  financial  commitments,  the  Company  does not have
employment agreements with any of its personnel.

Further,  the market  price of the  Company's  Common  Stock  could be  affected
adversely by the substantial  number of shares that are reserved for, and may be
issued in, the  future.  As of May 15,  2002,  there were  21,572,669  shares of
Common  Stock  issued  and  outstanding,  with an  additional  9,971,628  shares
reserved for future  issuance as follows:  4,400,000  shares  issuable  upon the
conversion of preferred  stock;  4,519,128  shares issuable upon the exercise of
options granted under the Company's  Stock Option Plan;  992,500 shares issuable
upon the exercise of warrants;  and 60,000 issuable upon the conversion of notes
payable.


Overview of the Company and its technology

Sonex Research,  Inc.  ("Sonex" or the  "Company"),  incorporated in Maryland in
1980,  is an  engineering  research  and  development  firm that is  seeking  to
commercialize  its  patented  proprietary   technology  (the  "Sonex  Combustion
System",  "SCS" or "Ultra Clean BurnTM  technology") for in-cylinder  control of
ignition and  combustion.  The Company was  co-founded  in 1980 by Dr. Andrew A.
Pouring,  a former  Professor  of  Aerospace  Engineering  and  Chairman  of the
Department of Aerospace  Engineering at the U.S. Naval  Academy.  At Sonex,  Dr.
Pouring  conducted  basic research into the principle of in-cylinder  control of
ignition and  combustion,  concentrating  on the piston.  By the late 1980's and
early  1990's,  the  development  of the  SCS  had  moved  in the  direction  of
chemical/turbulent  enhancement  of  combustion  through  investigation  of  the
effects  of  changing  the  chemical   characteristics   and  fuel  disbursement
characteristics within the combustion chamber.

The SCS  technology  for  in-cylinder  control of  ignition  and  combustion  is
designed to

       o   increase fuel mileage of gasoline engines
       o   reduce emissions of diesel engines
       o   permit small gasoline engines to run on safer diesel-type heavy fuels

The SCS improves the combustion of fuel in engines  through design  modification
of the pistons in four-stroke direct injected (DI) engines or the cylinder heads
in two-stroke spark-ignited (SI) gasoline engines to achieve  chemical/turbulent
enhancement  of  combustion.  The  SCS  process  changes  only a  single  engine
component  while  introducing  no  additional  parts and is  self-driven  by the
combustion process.

Sonex believes it can show the technical  feasibility  of achieving  higher fuel
economy standards while lowering emissions in a new class of DI gasoline engined
vehicles without sacrificing weight and vehicle safety. In 2000 Sonex introduced
its Stratified  Charge Radical  Ignition  (SCRI)  combustion  technology,  a new
branch of the SCS which Sonex believes will enable  practical  application of an
alternative  combustion process known as homogeneous charge compression ignition
(HCCI) that has the potential for lowering both emissions and fuel  consumption.
Unresolved issues with ignition have prevented practical  implementation of HCCI
to date.  Sonex  believes it has attained the control of ignition that will make
HCCI viable for commercial  application  such that the SCRI piston design,  with
further development, can enable DI gasoline engined automobiles,  currently sold
only in markets  outside  the U.S.  because  of  emissions  problems,  to become
emissions compliant in the U.S. while maintaining their current fuel consumption
advantages.  In addition,  the evolution of hybrid gasoline and electric powered
vehicles would be accelerated  since a major  improvement in engine fuel mileage
would provide opportunities for tradeoff of vehicle weight versus power.

SCS  reductions  of soot in  diesel  truck  engines  have been  confirmed  by an
independent  engine  consulting  firm.  SCS diesel engine  designs  require very
little engine  modification,  and should  provide cost  advantages  over complex
exhaust  aftertreatment  devices.  Evidence to date  indicates that the SCS is a
significant  new  engine  design  variable,  and that the  synergy of the SCS in
combination with exhaust gas  recirculation can reduce  aftertreatment  measures
and enable in-cylinder emissions reduction to meet future regulatory standards.

The SCS process for the  conversion of reliable,  lightweight,  SI,  two-stroke,
gasoline  engines  to start and  operate  on  diesel-type  heavy  fuels has been
applied  successfully  in a variety  of  applications  such as  small,  remotely
controlled  military unmanned aerial vehicles (UAVs).  The military now requires
such  engines  to  operate  on less  volatile  heavy  fuels to reduce the hazard
associated  with  gasoline,  making heavy fuel engines  (HFEs) more suitable for
applications where gasoline storage and use are undesirable.  Sonex HFEs achieve
power and fuel  consumption  substantially  equal to that of the stock  gasoline
engines.  Potential applications of the SCS heavy fuel conversion process can be
expanded to other military and commercial uses.

Sonex is seeking committed  business partners for further technical  development
and marketing of the various SCS engine applications. Sonex believes that having
one or more such partners  experienced in dealing with the engine and automotive
industries  on  state-of-the-art  technological  developments  is a key  to  the
commercial  acceptance of the SCS  technology in the form of  revenue-generating
license agreements for industrial production of SCS components.

As of March 31, 2002, the Company has three full-time employees, and engages the
part-time  services  of a  consultant  who serves as its  director  of  business
development  and manager of  government  programs.  The Company also engages the
services  of  several  other  consultants  as  needed.  The  Company  has  never
experienced  a strike or work  stoppage,  and  believes its  relations  with its
employees are good.


Competition

The  Company  faces   significant   competition  from  the  extensive   research
departments  of the  world's  major  vehicle  and  engine  manufacturers.  These
companies  exercise a bias toward in-house  technologies over those developed by
independent  suppliers.  Competition also comes from several  independent engine
testing  and  consulting  firms  around the world  which are in the  business of
developing engine  technologies.  The Company's  competitors have  substantially
greater  financial,  technical  and marketing  resources  than does the Company.
Accordingly,  the  Company  cannot be sure that it will  have the  resources  or
expertise to compete successfully in the future.

Although the experience and financial  resources of its  competitors  far exceed
those of the Company,  management  believes that the SCS can provide significant
advantages over the competition in terms of low cost, improved performance,  and
simplicity.


Secrecy and non-disclosure

Due to the  highly  competitive  nature  of the  world's  automotive  and  truck
industries,  in connection with its contracts and/or demonstration programs with
such  manufacturers,  Sonex is required to execute joint secrecy and  disclosure
agreements that, in most cases,  expressly prohibit the public disclosure of the
names and other  significant  information about the participants and the current
or  proposed  programs.  Failure  by  Sonex to  maintain  this  strict  level of
confidentiality would jeopardize its relationship with these organizations.


Overview of SCS design modifications

The SCS  technology  for DI diesel  engines  improves the process of  combustion
through a  combination  of  chemical  and fluid  dynamic  effects  that occur by
modifying the engine's  combustion  chamber and the processes  occurring  within
that chamber.  Patented SCS piston  designs for  four-stroke  engines  integrate
cavities called  micro-chambers  (MCs) which form a ring around the piston bowl,
with each MC  positioned  with respect to each spray from the fuel injector of a
DI engine.  The MCs are  designed  to  function  as  chemical  reactors  and are
connected to the piston bowl by vents.  The MCs produce  highly  active  radical
(chemical)  species from a fraction of the fuel-air  charge that are expelled on
the intake stroke of low compression ratio DI engines to fumigate incoming air.

The SCS "Low Soot"  design,  based on the Sonex U.S.  patents  issued in January
1999 and  January  2001,  is a recent  invention  in the  series for the SCS for
"classical"  DI diesel  engines and involves  re-arrangement  of SCS features to
exploit new fundamental  understandings  of fluid  dynamics.  The SCS "Low Soot"
design has shown  significant  reductions  in soot and oxides of nitrogen  (NOx)
while  maintaining  fuel  consumption  and power.  The key feature of the SCS DI
diesel  technology  is the presence of improved MCs in the piston which  produce
and conserve  intermediate  and radical chemical species from a small portion of
the incoming  fuel. The expulsion of these  materials at high velocity  enhances
turbulence  mixing,  achieving  better than a 50% soot  reduction  and a 10% NOx
reduction in the Sonex single cylinder,  DI, normally  aspirated research engine
with no change in injection  timing.  Sonex has also  demonstrated  that the SCS
technology can be transferred  to a modern  turbocharged,  intercooled DI diesel
engine.

SCS generated  radical  chemical species from a design similar to the "Low Soot"
design are also being used at Sonex in  relation  to an  alternative  combustion
process known as homogeneous  charge  compression  ignition (HCCI) that is being
examined by the  worldwide  automotive  industry.  HCCI has been studied by many
researchers  for years because,  in theory,  it can lower  emissions  while also
achieving  reduced  fuel  consumption,  because  compression  ignition  does not
require the use of a spark plug;  however,  the lack of a method for controlling
the  ignition  point  has  prevented  practical  implementation  of HCCI.  Sonex
believes it has attained the control of ignition  that will make HCCI viable for
commercial application by achieving radical assisted,  four-stroke combustion to
enable fully controllable compression ignition at low pressures as a function of
fuel  injection  timing,  a mode Sonex refers to as Stratified  Charge,  Radical
Ignition (SCRI).

With SCRI,  radical  (chemical)  species  that  enable  ignition  are created by
interaction of the injected fuel spray with specially designed MCs in the piston
side wall. The net result is an engine that is fully  controllable  at all loads
and speeds without limitation,  has extremely low emissions and the fuel economy
of a diesel engine.  On a DI, single cylinder  laboratory  engine at Sonex,  the
SCRI  reduced  NOx  emissions  by 80% and  smoke by 90% while  maintaining  fuel
consumption, using diesel-type fuels.

The SCRI combustion chamber  modifications make use of certain chemically active
products of combustion  known as "free radicals" that, in conventional  internal
combustion  engines,  are not carried from one combustion cycle to the next. The
SCRI process  isolates free radicals to be carried from one combustion  cycle to
the next to take  advantage of the combustion  enhancing  properties of the free
radicals,  thereby  enabling  ignition of all types of fuels and  allowing  more
complete  combustion  of the fuel.  The SCRI relies on direct  injection of fuel
into the cylinder (rather than in the intake manifold) as well as the production
of radicals for ignition.

The SCS engine  design  modifications  for heavy fuel  operation  in  two-stroke
engines  consist of a  machined  cylinder  head and  combustion  chamber  insert
integrated with a glow plug starting system.  For engines that have the cylinder
head and cylinder in one  casting,  the stock  cylinder  head is removed and the
remaining  cylinder casting is decked and machined for cylinder head screws. The
SCS starting system consists of a heavy fuel vaporizer block positioned  between
the carburetor and cylinder.



Primary Sonex initiatives

The Company seeks to commercialize  its SCS technologies for a variety of engine
applications  for  commercial  and military  use. To date,  Sonex has engaged in
development and  demonstration  programs with the engine industry and has sought
funding  from  the  federal  government  for  further  development  of  the  SCS
technologies.  Some of these proposed  projects are expected to achieve  certain
milestones  that will be key to the  commercial  development of the SCRI process
for automotive engines.

The next few  paragraphs  provide an overview of the primary  opportunities  for
Sonex.  Additional  detailed  information can be found in the Company's December
31, 2001 Annual Report on Form 10-KSB.


Gasoline  engined  vehicles:  With its SCRI  process,  Sonex intends to show the
technical  feasibility of achieving higher fuel economy standards while lowering
emissions in a new class of DI gasoline  engined  vehicles  without  sacrificing
weight  and  vehicle  safety.  Such an  achievement  could also  accelerate  the
evolution  of  hybrid  gasoline  and  electric  powered  vehicles  since a major
improvement in engine fuel mileage would provide  opportunities  for tradeoff of
vehicle weight versus power.

Initially,  Sonex must transition the results achieved by its SCRI process using
a   single-cylinder   laboratory   engine  on  diesel-type  fuels  to  gasoline.
Preliminary  work on gasoline at Sonex has  demonstrated  that the SCRI  process
does  achieve  the desired  ignition  and high rate of heat  releases  which are
necessary to achieve improved fuel  consumption and lower  emissions.  The first
stage of this  effort,  expected  to take at least six  months,  will  establish
feasibility and design  parameters and must also take place on a single cylinder
engine.  The emphasis on this first phase will be to establish a knowledge  base
upon which a prototype engine can be designed in a second phase.

Immediately  following  the first stage,  Sonex would be in a solid  position to
work with the auto  industry on  demonstration  projects to  transition  SCRI to
multi-cylinder  engines  so  gasoline  can be  burned  effectively  in  eventual
production  engines  of all  sizes.  Fortunately,  demonstration  projects  with
automotive   manufacturers  could  provide  results  fairly  quickly  since  the
sparkless  SCRI process can  advantageously  employ the centrally  located spark
plug hole of most production  4-valve per cylinder  engines for the installation
of the injector.


Truck  diesel  engines:  Sonex has  engaged  in  development  and  demonstration
programs with various international truck diesel engine  manufacturers.  The SCS
"Low Soot" piston  design for the  reduction  of  emissions  require very little
engine  modification,  and should provide cost  advantages  over complex exhaust
aftertreatment devices.

Recently one the world's leading engine  engineering  and powertrain  consulting
firms,  Ricardo Consulting  Engineers of the U.K.,  confirmed the soot reduction
capability  of  the  SCS  "Low  Soot"  design  in a DI  diesel  engine  used  in
medium-duty  trucks.  Ricardo  published  the  findings  in  a  technical  paper
presented  at the  Society  of  Automotive  Engineers'  May 2002 Fuels and Lubes
Conference.  Ricardo is currently  introducing the SCS "Low Soot" design results
to engine  manufacturers  and piston suppliers while Sonex continues its efforts
in that regard.


Heavy fuel engines:  The Company,  in its laboratory and under contract with the
U.S. military and defense  contractors,  also has applied a proprietary patented
SCS  starting  system  and  modified  combustion  chamber to the  conversion  of
reliable,  lightweight, SI, two-stroke, gasoline engines to start and operate on
JP-5/JP-8  standard  military  fuels (also  referred  to as "heavy  fuels") in a
variety of applications such as small,  remotely  controlled  military UAVs. The
military now requires  such engines to operate on less  volatile  heavy fuels to
reduce the hazard  associated  with  gasoline,  making  HFEs more  suitable  for
applications where gasoline storage and use are undesirable. The requirement for
a single  military  fuel is also a logistics  issue,  as the  military  seeks to
minimize the number and complexity of fuels.

Sonex HFEs achieve power and fuel consumption substantially equal to that of the
stock gasoline  engines.  The Company has performed HFE  conversions for various
sizes of small gasoline  engines for UAVs, and expects to be awarded shortly one
or more  contracts  from the U.S.  Department  of Defense (DoD) and or its prime
contractors,  although there can be no assurance. In addition, over the past few
months the Company has been developing a relationship  with a foreign UAV engine
company  and is  optimistic  of  executing  a  contract  later this year for HFE
conversion development.


Technology marketing partners:  Sonex believes commercial  acceptance of the SCS
technology can be accelerated  through the  establishment of relationships  with
entities which possess technical  development and marketing  capabilities within
the engine  industry.  In addition to the relationship  with Ricardo,  Sonex has
been in exploratory  discussions  with another  leading engine  engineering  and
powertrain  consulting  firm  regarding a formal  arrangement  for the technical
development and marketing of the various SCS engine applications.


Financial position and liquidity

Sonex has been operating under cash flow difficulties for several months, having
fallen  behind  in  payments  due to some  vendors.  Since  the fall of 2001 the
Company's  officers have received only a small portion of the cash  compensation
due them. In December  2001 Sonex took steps to reduce  further its monthly cash
requirements  by  eliminating  one  full-time   position  in  its  shop  and  by
restructuring compensation arrangements with its part-time consultants. A second
full-time position became vacant at the end of February 2002.

As of March 31, 2002, the Company had available cash and  equivalents of $28,086
and  accounts  receivable  of  $25,870.  At the end of March  2002,  the Company
received a purchase order of approximately $92,000 from a defense contractor for
a  four-month  effort to develop a small heavy fuel  engine for an  experimental
unmanned  aerial  vehicle.  A payment  of  $15,000  due upon the  receipt of the
purchase  order is included in the March 31, 2002 accounts  receivable  balance.
This amount was received in April 2002.

Since early 2001,  the  Company's  officers  have  voluntarily  and at their own
discretion deferred receipt of payment of significant  portions of their current
wages to reduce the Company's monthly cash  requirements.  Such wages payable to
the Company's  officers  totaling  $113,710 are included in the total of accrued
wages as of March 31, 2002. The continued  deferral of portions of current wages
by the Company's officers cannot be expected to continue  indefinitely,  and the
Company will be required to pay such accrued wages as soon as cash flow permits.
The amount and timing of such payments  will be determined at the  discretion of
the Company's  officers,  as these accrued wages are not subject to the terms of
the  Company's  written  agreement  with  current and former  employees to defer
payment of portions of their salaries as described in Note 6 to the accompanying
financial statements.

Based upon  available  resources,  current and projected  spending  levels,  and
expected revenue from current and anticipated contracts, management believes the
Company will have sufficient  capital to fund operations  through June 30, 2002.
The Company's prospects beyond that date are dependent upon its ability to enter
into  significant  funded  contracts  for  the  further  development  of its SCS
technology,  establish  joint  ventures  or  strategic  partnerships  with major
industrial concerns,  or secure a major capital infusion.  There is no assurance
that the Company will be able to achieve these  objectives.  If these objectives
are not  achieved,  the Company will have to reduce the scope of its  operations
even further,  primarily by laying off its remaining employees and, possibly, by
abandoning its facility. These circumstances could lead to bankruptcy as well.

The  Company  has  high   expectations  of  receiving  one  or  more  additional
revenue-generating contracts from the military in the near future for heavy fuel
engine development. Once such contracts are secured, the Company will supplement
its workforce as needed with  part-time  personnel  before  defining and filling
full-time  positions.  Sonex also intends to seek a commercial marketing partner
experienced  in dealing  with the industry on  state-of-  the-art  technological
developments.  In  addition,  in May 2002 the Company  engaged the services of a
professional  investor  relations  firm to develop,  implement  and  maintain an
ongoing  program to  increase  the  investment  community's  awareness  of Sonex
activities.


Results of operations

A net loss of  $125,664  was  recorded  for the first three  months of 2002,  as
compared  to  $193,889  for the  corresponding  period in 2001,  a  decrease  of
$68,225.  The  decrease in the loss was due  primarily  to  substantially  lower
personnel costs in 2002 versus 2001.

Defense  contracts  relate  to  the  Company's   technology  for  conversion  of
commercial  gasoline  fueled  engines  used in UAVs and the  like to heavy  fuel
operation.  Commercial revenue earned in connection with the Company's DI diesel
engine piston  technology is subject to the negotiated  amount,  if any, that an
engine  manufacturer  is willing to provide in funding to  partially  offset the
development  costs  incurred by the Company in applying its technology to one of
the manufacturer's  engines.  Cost of revenue primarily consists of direct labor
charges and direct purchases attributable to funded programs.


       Research and development (R&D) expenses:

R&D  expenses for the first three  months of the year  decreased by $60,371,  or
46%,  from  $131,876 in 2001 to $71,505 in 2002,  almost  entirely  due to lower
personnel  costs.  Net R&D personnel costs,  after  reclassification  of amounts
charged to cost of revenue,  decreased by $56,711, or 56%, from $101,136 in 2001
to $44,425 in 2002.  Amounts  charged to cost of revenue were $8,416 in 2001 and
$22,501 in 2002, resulting in total R&D personnel costs before  reclassification
of $109,552 in 2001 and $66,926 in 2002, a decrease of $42,626.

The decrease in overall R&D  personnel  costs  resulted  from a reduction in the
workforce,  including  consultants,  which was placed in effect late in 2001 and
continued into the first quarter of 2002. Payroll and related taxes and benefits
decreased by $25,046.  The Company  discontinued its consulting agreement at the
end of 2001 with the individual  residing in Europe who served as R&D Supervisor
and International  Liaison Officer.  This individual was compensated in the form
of restricted stock and cash, with related charges totaling $17,580 in the first
quarter of 2001.


       General and administrative (G&A) expenses:

Total G&A expenses for the first three months of the year  decreased by $14,160,
or 18%, from $78,650 in 2001 to $64,490 in 2002. The largest  expense  category,
personnel costs, accounted for most of the reduction in total G&A expenses.

Personnel costs decreased  $11,383,  from $55,673 in 2001 to $44,290 in 2002, or
20%,  primarily  as a result of lower  charges for  consulting  services,  which
declined  by  $10,108  from  $26,374 in 2001 to  $16,266  in 2002.  Charges  for
consulting services for the first quarter of 2001 included $5,000 related to the
former  president of the Company,  who was engaged on a part-time  basis under a
consulting  agreement that provided for annnual  compensation  of $20,000.  This
arrangement was terminated by mutual  agreement  effective June 30, 2001, and in
September 2001 this individual resigned as president but remains on the Board of
Directors.  An additional  $7,440 in 2001  represents  amortization  of deferred
compensation of charges resulting from the grant of stock options in 1997 to the
president by the Company's  principal  shareholder.  Amortization of the related
charges ended in December 2001.

ITEM 6.  EXHIBITS AND REPORTS ON FORM 8-K


  (a)    Exhibits:

         4   Instruments defining the rights of security holders (contained
             in the  Articles of  Incorporation  and  By-laws,  as amended,
             filed with the 1992 Annual Report on Form 10-KSB)


  (b)    Reports on Form 8-K:

       On January 15, 2002, the Registrant filed a Current Report on Form 8-K to
       disclose the prospects of receiving  one or more funded  contracts in the
       near future for application of its heavy fuel engine  technology,  and to
       disclose that it would need to raise additional capital.

       On February 6, 2002, the Registrant filed a Current Report on Form 8-K to
       disclose that feasibility testing of its SCRI combustion  technology by a
