FOR IMMEDIATE RELEASE:

AFS Sets New Standard for General Motors 5.3 Litre Vortec Engine

CANADA, ALBERTA, CALGARY, Mar. 7 -/E-Wire/-- Alternative Fuel Systems Inc. (CDNX:ATF) ("AFS" or the "Company") is pleased to announce that it has successfully applied its Sparrow compressed natural gas ("CNG") engine control system to GM's new 5.3 litre "Vortec" gasoline engine. This popular engine, currently being used by most of GM's light duty trucks and sport utility vehicles across North America, has proved difficult for traditional CNG fuelling systems because of its high level of integrated electronic control. After requests from several CNG conversion outfitters in the U.S., AFS took on the challenge of developing a sophisticated engine control system engineered specifically for this engine platform. AFS management believes the Sparrow system used in this application is the only retrofit system on the market which offers dual bank fuel control and full-authority electronic ignition timing.

AFS has installed its Sparrow system in the engine of a GMC Sierra truck, which is currently in the "on-road" verification stage. Acceleration and drivability are excellent and meet the performance expectations for this class of vehicle. Continued road testing, calibration and exhaust emission testing as well as demonstrations for select high-volume customers will progress through March.

"We believe this Sparrow application will present a significant new opportunity for us in the North American market where we have not yet had a big presence", commented AFS president, John C. Anderson. "Current engine technologies require independent bank fuel control and enhanced electronic ignition timing to meet the increasingly difficult performance and emissions standards. Once again, we have adapted our technology to be compatible with these engine requirements at a cost that will be attractive to customers". Alternative Fuel Systems Inc. is an environmental technology company providing innovative solutions to the global engine exhaust emissions problem. AFS has developed and commercialized electronic engine management technologies that enable diesel and gasoline engines to operate using natural gas. AFS is also at the forefront of research into exhaust aftertreatment technologies and hydrogen-based engine systems. AFS is headquartered in Calgary, Canada and trades on the CDNX as ATF.
