General Motors is offering the 2010 Buick LaCrosse CX with a new 2.4 liter Ecotec engine which develops 182horsepower (136 kW) and 172 lb-ft. of torque (233 Nm) and has an EPA rating of 30/19 mpg city/highway. This efficient powerplant features a sophisticated direct injection system and is also quite clean.

“Direct injection is a key component of GM’s ongoing strategy to useadvanced propulsion technology to help us deliver more fuel-efficientcars today and in the future,” said Tom Stephens, vice chairman, GlobalProduct Development. “GM is using multiple technology pathways toachieve increased efficiency and to diversify energy sources – andwe’re applying them where they make the most sense for customers whenit comes to efficiency, performance and cost.”

GM says that this engine is also very quiet and has very low maintenance costs. It is even equipped with GM’s Oil Life system,which uses a sophisticated algorithm to determine when it’s time for an oil change. Next year the current 3.0L V-6 will be discontinued and the Ecotec 2.4L and3.6L V-6 with variable valve timing will be the two engines offered in the vehicle. Also an AWD version will be offered with the V6 model.
