  ITEM 8.01 - OTHER EVENTS
  
  On March 13, 2006, the  Registrant  issued the following  announcement  over the
  newswire and posted it on its website (www.sonexresearch.com):
  
  
  SONEX RECEIVES $235,000 FOLLOW-ON PROJECT FOR UAV HEAVY FUEL ENGINE DESIGN
  
  
  ANNAPOLIS,  MARYLAND, March 13, 2006 - SONEX RESEARCH, INC. (OTC SONX), a leader
  in the field of  combustion  technology,  announced  that it has been  awarded a
  follow-on  project  worth  approximately  $235,000 to continue  development  and
  pre-production qualification of a heavy fuel engine (HFE) conversion process for
  a small,  commercially  available,  gasoline  engine  to start  and  operate  on
  standard military  kerosene-based  fuels (also referred to as "heavy fuels") for
  planned use in a production unmanned aerial veh icle (UAV).
  
  In October 2005 Sonex entered into an agreement  with an unnamed  customer worth
  approximately   $113,000  to  develop  a  combustion   system  to  convert  this
  two-stroke,  spark-ignited (SI) gasoline engine to heavy fuel operation based on
  the patented Sonex Combustion  System (SCS) modified  combustion  chamber design
  and  proprietary  starting  system  for  two-stroke  SI  engines.  This  Phase 2
  follow-on  award resulted from the successful  demonstration  to the customer in
  February  2006 of a "Proof of Concept"  SCS HFE prototype  operating  on JP-5
  heavy fuel. In Phase 2 Sonex will use its best efforts to develop, fabricate and
  qualify pre-production, flight ready engines.
  
  If Phase 2 is  successful,  additional  contemplated  phases  are for SCS  HFE
  flight certification testing and production introduction.  The agreement between
  the companies  grants the customer  sole use rights to the SCS HFE  conversion
  design for this model engine,  tied to a potential  production  supply agreement
  with Sonex, and return of the design rights to Sonex under certain conditions in
  the event the parties do not enter into a production supply agreement.
  
  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,  heavy  fuels to reduce the  hazard  associated  with
  gasoline.  In recent years,  most of the Company's revenue has been derived from
  development  and  demonstration  contracts  issued  by  DoD  activities  or  DoD
  contractors for SCS HFE conversion. In January 2006 Sonex announced a $272,700
  contract with a large international  defense contr actor to develop an SCS HFE
  design to convert  another small  gasoline  engine to start and operate on heavy
  fuels for potential use in a military UAV.

  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 tha t 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
  Reports on Form 10-KSB for the years ended December 31, 2004 and 2005 because it
  lacks the financial resources to eng age its independent  accountants to conduct
  audits of the December 31, 2004 and 2005  financial  statements,  and because it
  lacks the  staffing to prepare  the Form 10-KSB  itself due in large part to the
  amount of time  management has spent in responding to  litigation.  For the same
  reasons,  the  Company  has been  unable to file its  Quarterly  Reports on Form
  10-QSB for March 31, 2005,  June 30, 2005 and September 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. In  addition,  there can be no
  assurance  that a public market for the Company's  Common Stock will continue to
  exist.
