ITEM 5. - OTHER EVENTS AND REGULATION FD DISCLOSURE


On October 2, 2003, the Registrant  posted the following news announcement on
its website (www.sonexresearch.com):




SONEX RECEIVES $165,000 MILITARY CONTRACT FOR UAV HEAVY FUEL ENGINE CONVERSION

             Filed with the SEC as a Current Report on Form 8-K and
                posted to the Sonex website www.sonexresearch.com


ANNAPOLIS,  MARYLAND,  October 2, 2003 - SONEX  RESEARCH,  INC.  (OTC BB:  SONX)
announced  that it has  been  awarded  a  military  contract  for  approximately
$165,000 to develop a combustion system to convert two small gasoline engines to
start and operate on standard military kerosene-based fuels (also referred to as
"heavy fuels") for potential use in unmanned aerial vehicles (UAVs). The name of
the military customer and other contract details were not disclosed.

The  Department  of Defense  (DoD) now  requires  engines used in UAVs and other
military  applications for which gasoline  storage and use are  undesirable,  to
operate  on less  volatile,  kerosene-based  heavy  fuels to reduce  the  hazard
associated  with  gasoline.  Sonex will  design and  develop a heavy fuel engine
(HFE) conversion process for the two lightweight, two-stroke, spark-ignited (SI)
gasoline  engines based on the patented Sonex  Combustion  System (SCS) modified
combustion  chamber  design and  proprietary  starting  system for two-stroke SI
engines.

At its 2003 Annual  Meeting of  Shareholders  held on September 16, 2003,  Sonex
revealed  strategic  initiatives now taking shape,  particularly with respect to
plans  for  increasing  the  Company's  profile  within  the DoD for SCS  engine
technology.  Sonex is promoting the SCS process as an enabling  factor for heavy
fuel conversions, thereby creating a U.S.-based core defense systems capability.

In addition to this new contract  award,  Sonex has been  working  under a prime
contract from the Defense  Advanced  Research  Projects Agency (DARPA) on an SCS
piston  design  using the  Sonex  Controlled  Auto  Ignition  (SCAI)  combustion
process.  The SCAI is  applicable  to low  compression  ratio,  direct  injected
engines to enable  auto-ignition  and combustion with high rates of heat release
for a variety of fuels to achieve  reduced  emissions and increased fuel economy
in un-throttled, lightweight engines.

The DARPA  effort  calls for the  conversion  of an existing  six-cylinder,  SI,
four-stroke,  automotive engine from gasoline  operation to heavy fuel operation
through a custom common rail fuel  injection  system and an SCAI piston  design.
DARPA  may  consider  this  route  to  achieve  an HFE  for  potential  use in a
developmental UAV or other engine applications. The SCAI process for four-stroke
engines achieves sparkless ignition-combustion of the heavy fuel without raising
the compression  ratio to the levels found in diesel engines.  As a result,  the
inherent  light weight of the gasoline  engine is preserved and peak  combustion
pressures are limited to those of gasoline operation.

Sonex,  in other  ongoing  programs,  has been  applying  SCS piston  designs to
achieve  in-cylinder  control of ignition  and  combustion  for  increased  fuel
mileage and reduced  emissions  in  vehicular  engines.  Under  funding from the
Department  of Energy  (DOE)  Sonex is now  developing  a piston  design  for an
automotive  diesel engine  application.  Outcomes from the current programs with
DOE on diesel fuel and DARPA on heavy fuel could  validate  SCS  technology  for
application to gasoline  powered  automotive  engines.  With the SCAI combustion
process,  Sonex  hopes to  enable  gasoline  direct  injected  (GDI)  automobile
engines, currently manufactured and sold only in markets outside the U.S. due to
high emissions,  to become emissions  compliant in the U.S. while providing fuel
consumption benefits.

About Sonex

Sonex  Research,  Inc.,  a leader  in the  field of  combustion  technology,  is
developing its patented Sonex Combustion  System (SCS)  piston-based  technology
for in-cylinder  control of ignition and  combustion,  designed to increase fuel
mileage and reduce  emissions  of internal  combustion  engines.  Sonex plans to
complete  development,  commercialize  and  market  its  Sonex  Controlled  Auto
Ignition (SCAI)  combustion  process to the automotive  industry to improve fuel
efficiency of gasoline powered vehicles in response to forthcoming  increases in
national vehicle fuel mileage standards.  Additionally,  independent third-party
testing has confirmed the potential of the SCS application  for  direct-injected
diesel  engines to reduce  harmful  soot  in-cylinder  without  increasing  fuel
consumption.  Other SCS  designs are being used to convert  gasoline  engines of
various sizes to operate on safer, diesel-type "heavy fuels" for use in military
and commercial applications requiring light weight and safe handling and storage
of fuel, such as in UAVs (unmanned aerial vehicles).
