California Air Resources Board to Lease Hydrogen Fuelled Toyota Prius Vehicles - News Item

IRVINE, Calif., June 26, 2006 /PRNewswire-FirstCall via COMTEX/ -- Quantum Fuel Systems Technologies Worldwide, Inc., (Nasdaq: QTWW) today announced that it received notice from the California Air Resources Board of its intent to lease 4 hydrogen-fueled Toyota Prius hybrid vehicles. These hydrogen hybrid vehicles will be put in service by the State of California later this year as part of the California Hydrogen Highway Network (CaH2Net).

CaH2Net is a State initiative to promote the use of hydrogen as a means of diversifying our sources of transportation energy used, while ensuring environmental and economic benefits. To be implemented in three phases, the California Hydrogen Blueprint Plan outlines a path to 250 hydrogen fueling stations and 20,000 hydrogen fueled vehicles which will help set the stage for the eventual full-scale commercialization of these technologies.

Quantum's H2Hybrid package for the Toyota Prius includes an electronic multi-point hydrogen injection system, turbocharger and intercooler, compressed hydrogen fuel storage module, hydrogen fuel delivery system and Federal Motor Vehicle Safety Standards (FMVSS) crashworthy design and validation. In addition to performing in specified starting conditions and meeting certain drivability specifications, the vehicles have been designed and tested to achieve SULEV (Super Ultra Low Emissions Vehicle) emissions standards and have undergone crash testing to verify the safety of the converted vehicles. Quantum is also developing an H2Hybrid package for the Ford Escape Hybrid sport utility vehicle, in conjunction with the U.S. Army, for use as an administrative vehicle as well as a hydrogen technology demonstrator.

"Quantum is pleased to have its hydrogen hybrid Toyota Priuses selected to be part of the California Hydrogen Highway initiative. Interest in Quantum's hydrogen hybrid technologies continues to grow, with 30 hydrogen Priuses currently in operation in Southern California and 23 more now on order, including 15 that are bound for Norway," said Alan P. Niedzwiecki, President and CEO of Quantum. "We are proud to supply our California-developed alternative fuel and alternative energy technologies as solutions to the environmental and energy issues impacting the State, our nation, as well as the rest of the world. Quantum is ready today to fulfill the California Hydrogen Blueprint's plan for 20,000 hydrogen fueled vehicles."
