  ITEM 8.01 - OTHER EVENTS
  
  On June 22, 2005,  the  Registrant  issued the following  announcement  over the
  newswire and posted it on its website (www.sonexresearch.com):
  
  
  
                 SONEX RECEIVES $300,000 FOLLOW-ON TASK FROM DARPA
  
  
  ANNAPOLIS,  MARYLAND,  June 22, 2005 - SONEX RESEARCH, INC. (OTC SONX), a leader
  in the field of combustion technology, announced that it has received a $300,000
  follow-on task from the Defense  Advanced  Research  Projects  Agency (DARPA) to
  continue development of a multi-cylinder, four-stroke, high power output, "heavy
  fuel" engine (HFE) combustion process for potential  Department of Defense (DoD)
  applications such as unmanned aerial vehicles (UAVs).
  
  Sonex, a small business, has performed a best efforts technology development and
  demonstration of the patented Sonex Combustion System (SCS) to enable the use of
  JP-5/8 military  kerosene-based "heavy fuel" in lightweight,  four-stroke piston
  engines.  This  project  is  sponsored  by  DARPA  as a  technology  feasibility
  demonstration  of a means for  lightweight  piston  engines to comply with a DoD
  policy directive that mandates heavy fuel for all engines.  Gasoline engines are
  typically 25% to 30% lighter than diesel engines; thus, fully qualified, adapted
  gasoline engine designs that could burn hard-to-ignite diesel and kerosene-based
  heavy fuels would address DoD performance, logistics and safety requirements.
  
  The SCS improves the combustion of fuels in  four-stroke,  direct  injected (DI)
  engines through design modification of the pistons to achieve chemical/turbulent
  enhancement of combustion.  One form of the SCS,  called Sonex  Controlled  Auto
  Ignition  (SCAI),  allows  ignition and combustion of low cetane fuels,  such as
  JP-5/8, by controlled auto-ignition at moderate compression ratios, and operates
  at controlled peak cylinder pressures,  which should allow the design of lighter
  weight HFEs rather than the heavy weight required by normal diesel engines.
  
  To date under the existing agreement, Sonex adapted a lightweight, six-cylinder,
  normally aspirated, gasoline,  spark-ignited (SI), automotive engine to the SCAI
  unthrottled,  lean-burn,  direct fuel injection combustion process to run on JP5
  heavy fuel. This engine was run normally  aspirated and  turbocharged to examine
  performance  relative to the combustion chamber. In addition,  Sonex adapted its
  3-cylinder  turbocharged  diesel  laboratory  engine to  compare  a  diesel-like
  combustion chamber to the gasoline-like combustion chamber of the first engine.
  
  With its SCAI process using heavy fuel, Sonex achieved the following  laboratory
  results:
  
  *  Complete  control of ignition by means of SCAI  chemical  ignition  using
     fuel injection  timing.
  
  *  Control  of  peak  cylinder  pressures   consistent  with lightweight
     aluminum engine design.
  
  *  Demonstration  of the advantages of the  diesel-like  combustion  chamber and
     turbocharging  for high power output and low smoke at a fuel consumption rate
     of 0.35 lbs. of fuel per  horsepower  hour.  This is in the range of modern
     diesel engines.
  
  The  objective  of  this  follow-on  task  is to  apply  the  SCS  SCAI  to  the
  reconfiguration of a commercially  available automotive engine that approximates
  the  combustion  chamber,  displacement,  bore and stroke of an objective 400 hp
  HFE.  Demonstration of the performance  criteria of this reconfigured  engine is
  intended to provide the impetus  needed to  establish a sustained  DoD effort to
  develop and qualify lightweight HFEs.
  
  This is the  second  DARPA  funded  follow-on  task to the  agreement,  which is
  structured  as an "other  transaction"  pursuant  to 10 U.S.C.  ss.  2371 and by
  Section  845 of the  National  Defense  Authorization  Act for Fiscal Year 1994,
  Public Law 103-160, as amended.
  
  The  outcomes  from  this  Agreement  also  relate  to the use of SCS SCAI  with
  gasoline and could have significant potential for commercial  application in the
  automotive market. U.S. fuel mileage  improvement for production  automobiles by
  model year 2014 is addressed in the House and Senate 2005 Energy Bills.  Section
  774 of the House bill passed in April 2005 states: "Not later than 30 days after
  the date of the enactment of this Act, the Administrator of the National Highway
  Traffic  Safety  Administration  shall initiate a study of the  feasibility  and
  effects of reducing by model year 2014, by a significant percentage,  the amount
  of fuel consumed by automobiles."  Sonex seeks to be at the forefront in 2005 by
  providing  compelling  data on how  its  SCS  SCAI  technology  for  unthrottled
  gasoline  direct  injection  (GDI) engines could cost  effectively  improve fuel
  mileage 25% to 30% and enable reduced exhaust  emissions.Sonex  has been seeking
  partners and other funding arrangements to support this quest.

  About DARPA
  
  The Defense  Advanced  Research  Projects Agency (DARPA) is the central research
  and development organization for the Department of Defense (DoD). It manages and
  directs  selected basic and applied  research and development  projects for DoD,
  and pursues research and technology where risk and payoff are both very high and
  where success may provide dramatic  advances for traditional  military roles and
  missions.  More  information  about  DARPA  can  be  found  on the  Internet  at
  www.darpa.mil.
  
  
  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.  Additionally,  independent third-party
  testing has confirmed the potential of the SCS application  for  direct-injected
  diesel  engines  to  significantly   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).
