Oshawa, Ontario – General Motors’ 3.6-litre direct injection V6 has been named to Ward’s AutoWorld magazine’s 2009 “Ten Best Engines” list for North America. Produced at GM Canada’s St. Catharines, Ontario powertrain facility, the engine is part of GM’s overall strategy to equip vehicles with advanced propulsion technologies that improve fuel economy and reduce emissions.
This is the second year that the magazine’s editors have recognized this engine, which is in the 2008 Cadillac CTS – Motor Trend’s 2008 Car of the Year – and six other GM models. The award will be presented in January at the North American International Auto Show.
“We are pleased that the results of our green by design transformation are being recognized,” said David Paterson, vice president of corporate affairs for GM of Canada. “Results like these reflect the aggressive focus we’ve placed on improving fuel economy and reducing vehicle emissions through advanced engine and transmission technologies.”
GM’s 3.6-litre V6 engine with variable valve timing and direct injection technology is one of the most fuel-efficient in GM’s high-feature engine family, delivering a three per cent fuel economy improvement over its predecessor. The 2008 CTS, when equipped with the 3.6-litre V6 VVT with direct injection and six-speed automatic transmission, consumes just 7.5 L/100 km highway and 10.1 L/100 km combined.
The application of direct injection also reduces cold-start hydrocarbon emissions by 25 per cent. With direct injection, fuel is sprayed directly into the engine cylinder, where it is mixed with air. As the fuel vaporizes in the cylinder, the air and fuel mixture is cooled. This enables the use of a higher compression ratio, which improves engine efficiency and performance.
In addition to the Cadillac CTS, the 3.6-litre DI V6 engine is available in the 2009 Buick Enclave, Cadillac STS, Chevrolet Traverse, GMC Acadia, Saturn Outlook and Saturn Vue 2-Mode Hybrid.
