“Direct injection is a key component of GM’s Advanced Propulsion Technology Strategy that uses multiple technology pathways to achieve increased efficiency and the diversification of energy sources,” said Tom Stephens, vice chairman, Global Product Development. “Because there is no single solution, we’re applying advanced technology where it makes the most sense for customers in regard to fuel efficiency, performance and cost. The efficiency gain with direct injection represents a great technological value that customers can benefit from immediately.”
A total of 15 2009 and 2010 models are already benefiting from upgraded direct injection engines and General Motors says that more are to come in the next few months as it continues its efforts in this particular area.
Buick Enclave for example delivers a highway rating of 24 mpg (FWD models) with the upgraded 3.6-liter DI engine while the LaCrosse improves the initial figures with the help of uprated 3.0-liter V6 and 3.6-liter V6.
Cadillac CTS and CTS Sport Wagon will come standard with a 3.0-liter DI V6 engine starting in 2010, with the sedan producing 26 mpg on the highway. Other upgraded models include Cadillac SRX, Cadillac STS, Chevrolet Camaro, Chevrolet Cobalt SS, Chevrolet Equinox, Chevrolet HHR SS, Chevrolet Traverse, GMC Acadia, Pontiac Solstice GXP, Saturn Outlook and Saturn Sky Red Line.
