    2010 Buick LaCrosse – First “Nice Looking” Buick in a very long time.

    GM's Ecotec 2.4L I-4 has been awarded Ward's Auto World magazine's 2010 "10 Best Engines" for North America. The direct injected engine with variable valve timing helps deliver segment-best highway fuel economy in GM's popular new crossovers, the Chevrolet Equinox and GMC Terrain. The engine also debuts in the all-new Buick LaCrosse and Regal sedans next year.

    Ward's reviewed 34 engines from 13 automakers in the competition. Winners were chosen based on several factors, including power, NVH, fuel efficiency, new technology and comparative data for similar engines.

    The new Ecotec 2.4L engine includes technology that provides a number of benefits. "Direct injection (DI) was designed into the 2.4L to boost fuel efficiency and for refined power," said Chris Meagher, chief engineer for Ecotec engines. "The VVT (variable valve timing) system is tuned to work in tandem with direct injection to achieve optimum fuel economy and lower emissions. The engine achieves a respectable 182 horsepower and 172 lb-ft of torque, which makes for a pleasing customer driving experience."

    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. Direct injection also reduces cold-start hydrocarbon emissions by up to 25 percent.

    The Ecotec 2.4L engine is an all-aluminum, dual overhead cam, four-valve engine with forged steel connecting rods and oil spray cooling for reduced friction and noise. In all models, the engine is mated to a highly efficient six-speed automatic transmission.

    A good engine, but still one liter too big. They're working on that solution now, and by next holiday season, the Fam0 1.4L should be hittin' the streets.

    This motor is in my '09 Malibu, and I'm very pleased with it. More get-up-n-go than expected. I waited til the '09 model so I could get it with the 6 spd trans., and I think that definitely helps on the FE.

    It is a very pretty car, particularly in the maroon they showed.

    The engine is interesting and probably about right for a large family sedan. It is certainly an improvement over the huge V8s that have been the order of the day in the past. Not there yet perhaps, but one can feel that some progress is being made with the larger public.

    Hi All:

    ___The problem with GM’s efforts is that crude is beginning to make a run at $100 per again and GM, along with everyone else has not even begun to catch up with where this monster is heading over the next few years. A 2 to 4 mpg improvement over a 5-year cycle will not keep up with the expected costs of fuel over the intermediate and longer term.

    ___Good Luck
