PREAMBLE

Item 1.	Security and Issuer.  
  
	This statement relates to shares of the Class A common  
stock, $0.00 par value (the "Shares") of Amerigon Incorporated, a  
California corporation (the "Company").  The principal executive  
offices of the Company are located at 404 East Huntington Drive,  
Monrovia, CA 91016.  
  
Item 2.	Identity and Background.  
  
	Item 2 is amended as follows:  
  
	This statement is being filed by FMR Corp., a Massachusetts  
Corporation ("FMR").  FMR is a holding company one of whose  
principal assets is the capital stock of a wholly-owned  
subsidiary, Fidelity Management & Research Company ("Fidelity"),  
which is also a Massachusetts corporation.  Fidelity is an  
investment advisor which is registered under Section 203 of the  
Investment Advisors Act of 1940 and which provides investment  
advisory services to more than 30 investment companies which are  
registered under Section 8 of the Investment Company Act of 1940  
and serves as investment advisor to certain other funds which are  
generally offered to limited groups of investors (the "Fidelity  
Funds").  Various directly or indirectly held subsidiaries of FMR  
are also engaged in investment management, venture capital asset  
management, securities brokerage, transfer and shareholder  
servicing and real estate development.  The principal offices of  
FMR and Fidelity are located at 82 Devonshire Street, Boston,  
Massachusetts 02109.  
  
	Members of the Edward C. Johnson 3d family are the  
predominant owners of Class B shares of common stock of FMR  
representing approximately 49% of the voting power of FMR.  Mr.  
Johnson 3d owns 12.0% and Abigail Johnson owns 24.5% of the  
aggregate outstanding voting stock of FMR.  Mr. Johnson 3d is the  
Chairman of FMR.  The Johnson family group and all other Class B  
shareholders have entered into a shareholders' voting agreement  
under which all Class B shares will be voted in accordance with  
the majority vote of Class B shares.  Accordingly, through their  
ownership of voting common stock and the execution of the  
shareholders' voting agreement, members of the Johnson family may  
be deemed, under the Investment Company Act of 1940, to form a  
controlling group with respect to FMR.  The business address and  
principal occupation of Mr. Johnson 3d is set forth in Schedule A  
hereto.  
  
	The name, residence or business address, principal  
occupation or employment and citizenship of each of the executive  
officers and directors of FMR are set forth in Schedule A hereto.  
  
	Within the past five years, none of the persons named in  
this Item 2 or listed on Schedule A has been convicted in any  
criminal proceeding (excluding traffic violations or similar  
misdemeanors) or has been a party to any civil proceeding and as  
a result thereof was or is subject to any judgment, decree or  
final order enjoining future violations of, or prohibiting or  
mandating activities subject to federal or state securities laws  
or finding any violations with respect to such laws.  
  
Item 3.	Source and Amount of Funds or Other Consideration.  
  
	Item 3 is amended as follows:  
  
	The Fidelity Funds which own or owned Shares purchased in  
the aggregate 220,000 Shares for cash in the amount of  
approximately $1,760,000, including brokerage commissions.  The  
Fidelity Funds used their own assets in making such purchase and  
no part of the purchase price is represented by borrowed funds.    
  
	The Accounts of FMTC which own or owned Shares purchased in  
the aggregate 330,000 Shares for cash in the amount of  
approximately $2,768,125, including brokerage commissions.  The  
Accounts used their own assets in making such purchase and no  
part of the purchase price is represented by borrowed funds.    
  
	On March 1, 1996, the Shares beneficially owned by the  
Fidelity Funds and the Accounts decreased by 550,000 Shares as a  
result of the event described in Item 5(c) below.  
  
Item 4.	Purpose of Transaction.  
  
	Item 4 is amended as follows:  
  
	The purpose of Fidelity in having the Fidelity Funds and the  
Accounts purchase Shares is to acquire an equity interest in the  
Company in pursuit of specified investment objectives established  
by the Board of Trustees of the Fidelity Funds and by the  
investors in the Accounts.  
  
	Fidelity may continue to have the Fidelity Funds and the  
Accounts purchase Shares subject to a number of factors,  
including, among others, the availability of Shares of sale at  
what they consider to be reasonable prices and other investment  
opportunities that may be available to the Fidelity Funds and  
Accounts.  
  
	Fidelity intends to review continuously the equity position  
of the Fidelity Funds and Accounts in the Company.  Depending  
upon future evaluations of the business prospects of the Company  
and upon other developments, including, but not limited to,  
general economic and business conditions and money market and  
stock market conditions, Fidelity may determine to cease making  
additional purchases of Shares or to increase or decrease the  
equity interest in the Company by acquiring additional Shares, or  
by disposing of all or a portion of the Shares.  
  
	Fidelity has no present plan or proposal which relates to or  
would result in (i) an extraordinary corporate transaction, such  
as a merger, reorganization, liquidation, or sale of transfer of  
a material amount of assets involving the Company or any of its  
subsidiaries, (ii) any change in the Company's present Board of  
Directors or management, (iii) any material changes in the  
Company's present capitalization or dividend policy or any other  
material change in the Company's business or corporate structure,  
(iv) any change in the Company's charter or by-laws, or (v) the  
Company's Class A common stock becoming eligible for termination  
of its registration pursuant to Section 12(g)(4) of the 1934 Act.  
  
Item 5.	Interest in Securities of Issuer.  
  
	Item 5 is amended as follows:  
  
	FMR, Fidelity, beneficially own all 0 Shares.  
  
	(a)	FMR and FMTC beneficially own, zero Shares, or  
approximately 0.00% of the outstanding Shares of the Company.   
Neither FMR, Fidelity, nor any of its affiliates nor, to the best  
knowledge of FMR, any of the persons named in Schedule A hereto,  
beneficially owns any other Shares.  The combined holdings of  
FMR, Fidelity, and FMTC are 0 Shares, or approximately 0.00% of  
the outstanding Shares of the Company.  
  
	(b)	Not applicable.  
  
	(c)	On March 1, 1996, the reporting person's beneficial  
ownership of Shares decreased by 550,000 Shares as a result of  
(i) the termination of the reporting person's interest in two  
Accounts and a Fidelity Fund (a private investment partnership)  
and (ii) the termination of investment management agreements FMTC  
and Fidelity had with such Accounts and Fidelity Fund,  
respectively.  
  
	(d)	Except as set forth in Schedule B, neither FMR, or any  
of its affiliates, nor, to the best knowledge of FMR, any of the  
persons named in Schedule A hereto has effected any transaction  
in Shares during the past sixty (60) days.  
  
	(e)	Inasmuch as FMR is no longer the beneficial owner of  
any of the number of shares outstanding, FMR has no further  
reporting obligation under Section 13(d) of the Securities  
Exchange Act of 1934 or the rules and regulations promulgated by  
the Securities and Exchange Commission thereunder.  This
