ITEM 8.01 - OTHER EVENTS

On September 27, 2006, the Registrant  posted the following  announcement on its
website (www.sonexresearch.com):



SONEX FILES MOTION TO DISMISS AMENDED INVESTOR LAWSUIT


ANNAPOLIS,  MARYLAND,  September  27,  2006 - SONEX  RESEARCH,  INC.  (OTC SONX)
announced that it is seeking  dismissal of an amended  federal  lawsuit filed in
August 2006 by a group of  Pennsylvania  investors.  Their original  lawsuit was
dismissed in July 2006 by the U.S.  District  Court for the Eastern  District of
Pennsylvania  for  failure  to meet the  legal  standard  for  bringing  a valid
complaint under  applicable  federal and state  securities laws. Last week Sonex
filed a Motion to Dismiss the refiled  lawsuit for failure again to state claims
for relief as a matter of law.

The original  Complaint was filed in February 2005 by Bruce W. Majer of Plymouth
Meeting, PA, Allen W. Fortna of Whitehall,  PA, and the Hermitage Partnership of
Philadelphia, PA (together,  referred to as the "Investors").  The Complaint was
an action for federal and state securities fraud,  common law fraud, and related
claims by the  Investors  who believe they were  induced to purchase  securities
based on a series of alleged  misstatements,  misrepresentations  and omissions,
and was filed against  Sonex,  its former  President,  CEO and director Roger D.
Posey,  former director Jim Z.I.  Williams,  current CFO, Secretary and director
George E.  Ponticas,  and Dr. Andrew A. Pouring,  current Sonex  Chairman of the
Board, CEO and President.  The Investors sought the return of $175,000 in equity
investments  made in Sonex during  2004.  Sonex notes that Mr. Majer is a former
colleague of Mr. Posey.

In March 2005 Sonex  filed its Motion to Dismiss  the  Complaint  for failure to
state a  cognizable  claim as a matter of law,  which  motion was granted by the
Court on July 19, 2006. The Plaintiffs had 30 days to file an Amended Complaint.

The  Amended  Complaint  restates  the  claims of the  original  lawsuit,  cites
additional examples of alleged misrepresentations, and makes several allegations
concerning  the  involvement  of former Sonex  consultant  James A. Rose, II, of
Arnold,  Maryland,  president  of  Global  Equity  Consultants,  Inc.  ("GECI"),
contending that Mr. Rose had authority to act on behalf of Sonex and his alleged
misrepresentations,  in part,  induced the  Plaintiffs  to invest.  Despite such
allegations, the Amended Complaint does not name Mr. Rose or GECI as defendants.
Mr. Rose  introduced  Mr.  Posey to Sonex and was then engaged by the Company in
February 2004 to provide financial  advisory and other consulting  services.  As
described  in  previous  news  releases,  the  Company is  currently  engaged in
litigation with Mr. Rose.

It  is  the  opinion  of  management  that  the  Plaintiffs  have  attempted  to
orchestrate a securities fraud claim to escape what they had come to perceive as
a  downside  investment.  Like  the  original  Complaint,   Plaintiffs'  Amended
Complaint  collapses  under  the  weight of the  total  mix of  information  and
cautionary statements available at the time of their investment. Moreover, while
the  Amended  Complaint  contains  admittedly  more  detail  than  the  original
Complaint,  the additional facts alleged still do not adequately plead intent to
deceive or loss  causation  for  purposes  of the  applicable  federal and state
securities laws.

Management  believes  that the  Company  will  prevail  again as it did when the
original  lawsuit was dismissed.  It is  anticipated  that the Court will decide
this motion prior to issuing any order concerning discovery on the merits of the
allegations of the Complaint.

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.




RISK FACTORS

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  Annual
Reports on Form 10-KSB for the years ended  December 31, 2004 and 2005 primarily
because it lacks the  financial  resources to engage an  independent  registered
public accounting firm to conduct an audit of the related  financial  statements
and because it lacks the  staffing to prepare the Forms 10-KSB due in large part
to the amount of time management has devoted and the amount of funds the Company
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 2005 and 2006. 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.

                                 ###
