Item 7.01      Regulation FD Disclosure

As previously reported in a Current Report filed on Form 8-K filed with the SEC on March 23, 2016, Quantum Fuel Systems Technologies Worldwide, Inc. (the “Company”) filed a voluntary petition for relief (the “Bankruptcy Petition) under chapter 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Central District of California (the “Bankruptcy Court”). The Company will continue to manage its properties and operate its business as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Court and orders of the Bankruptcy Court. Through the Chapter 11 case, the Company seeks to implement a sale of substantially all assets of the Company pursuant to section 363(b) of the Bankruptcy Code (the “363 Sale”).

On May 18, 2016, the Company filed its monthly operating report (the “Monthly Operating Report”) for the month ended April 30, 2016 with the Bankruptcy Court. The Monthly Operating Report is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information contained in this Current Report on Form 8-K shall not be deemed “filed” for purposes of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

Cautionary Note Regarding the Monthly Operating Report

The Company cautions investors and potential investors not to place undue reliance upon the information contained in the Monthly Operating Report, which was not prepared for the purpose of providing the basis for an investment decision relating to any securities of the Company. The Monthly Operating Report is limited in scope, covers a limited time period and has been prepared solely for the purpose of complying with the monthly reporting requirements applicable in the Chapter 11 case and is in a format acceptable to the U.S. Trustee. The Company is not required to publicly update the Monthly Operating Report to reflect more current facts or estimates or the occurrence of future events, including if the facts, estimates and assumptions upon which the Monthly Operating Report is based are erroneous. The Monthly Operating Report was not audited or reviewed by independent accountants, was not prepared in accordance with generally accepted accounting principles in the United States, is in a format prescribed by applicable bankruptcy laws, and is subject to future adjustment (which may be material) and reconciliation. There can be no assurance that, from the perspective of an investor or potential investor in the Company’s securities, the Monthly Operating Report is complete. The Monthly Operating Report also contains information for periods which are shorter or otherwise different from those required in the Company’s reports pursuant to the Exchange Act and such information might not be indicative of the Company’s financial condition or operating results for the period that would be reflected in the Company’s financial statements or in its reports pursuant to the Exchange Act. Results set forth in the Monthly Operating Report should not be viewed as indicative of future results.

Other Cautionary Statements

The Company’s shareholders are cautioned that trading in the Company’s common stock during the pendency of the Chapter 11 Case is highly speculative and involves substantial risks. Trading prices for the Company’s common stock may bear little or no relationship to the actual recovery, if any, by shareholders in the Company’s Chapter 11 case. Accordingly, the Company urges extreme caution with respect to existing and future investments in its common shares.

If sufficient funds are not generated by the sale process or any Chapter 11plan in excess of secured claims, priority claims and general unsecured claims, the holders of the Company’s common stock might receive no

distribution on account of their interests and, in the event of a Chapter 11 liquidation plan, their existing common stock may be cancelled. If certain requirements of the Bankruptcy Code are met, a liquidation plan can be confirmed notwithstanding its rejection by the Company’s equity security holders and notwithstanding the fact that such equity security holders do not receive or retain any property or other value in respect of their equity interests.
