        SONEX SIGNS $113,000 AGREEMENT FOR UAV HEAVY FUEL ENGINE CONVERSION
  
  
  ANNAPOLIS,  MARYLAND,  October 24, 2005 - SONEX  RESEARCH,  INC.  (OTC SONX),  a
  leader in the field of combustion  technology,  announced  that it has signed an
  agreement  with an unnamed  customer  for  approximately  $113,000  to develop a
  combustion  system to convert a small  gasoline  engine to start and  operate on
  standard military  kerosene-based  fuels (also referred to as "heavy fuels") for
  potential use in a production unmanned aerial vehicles (UAV).
  
  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 small,  two-stroke,  spark-ignited  (SI) gasoline
  engine based on the patented Sonex Combustion  System (SCS) modified  combustion
  chamber design and proprietary starting system for two-stroke SI engines.
  
  Under this  agreement,  Sonex will use its best efforts over the next few months
  to  develop a "Proof of  Concept"  prototype  operating  on JP-5  heavy fuel for
  detailed test and  evaluation by the customer.  Upon  attainment of a successful
  prototype,  the two companies  anticipate  proceeding to a follow-on program for
  the development,  fabrication and qualification of pre-production,  flight ready
  engines.

  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).
  
  
  CAUTION REGARDING FORWARD-LOOKING STATEMENTS
  
  "Forward-looking"  statements  contained in this report, as well as all publicly
  disseminated  material about the Company, are made pursuant to the "safe harbor"
  provisions of the Private  Securities  Litigation Act. Such statements are based
  on current  expectations,  estimates,  projections and assumptions by management
  with respect to matters such as commercial acceptance of the SCS technology, the
  impact of  competition,  and the  Company's  financial  condition  or results of
  operations.  Readers are cautioned  that such  statements  are not guarantees of
  future  performance and involve risks and uncertainties  that could cause actual
  results to differ  materially from those  expressed in any such  forward-looking
  statements.
  
  Additional  information  regarding  the risks  faced by Sonex is provided in the
  Company's  periodic  filings with the Securities and Exchange  Commission  (SEC)
  under the heading "Risk  Factors".  Such filings are available upon request from
  the Company or online in the SEC's EDGAR database at  www.sec.gov.  The Company,
  however,  is delinquent in its filings with the SEC. It has not filed its Annual
  Report on Form 10-KSB for the year ended  December 31, 2004 because it lacks the
  financial resources to engage its independent accountants to conduct an audit of
  the December 31, 2004 financial statements and because its limited staff has not
  had time to prepare the Form 10-KSB  itself.  For the same reasons,  the Company
  has been unable to file its Quarterly  Reports on Form 10-QSB for March 31, 2005
  and June 30, 2005. The Company is unable to predict when it will be able to make
  these  filings and there can be no  assurance  that the filings  will be made at
  all.
