New U.S. government auto safety regulations provide a new incentive to Technologies M4 Inc. (TM4) to advance the development of its revolutionary electric drive system for a wide range of electric-powered cars and light trucks, the company's president said here today. David Johnston said recently-revised brake test requirements for electric cars create a more favourable environment for the development of the TM4 drive system for various vehicles including four-wheel drive and sport utilities. He spoke to news media at the 17th International Electric Vehicle Symposium in Montreal.
