General Motors recently added another engine—a 2.4-liter I-4 with direct fuel injection—to the 2010 Buick LaCrosse portfolio. Buick hopes the direct injection I-4, shared with the new 2010 Chevrolet Equinox, will attract customers looking for luxurious amenities mixed with impressive fuel economy.
Originally, GM announced that the 2010 Buick LaCrosse would be available with only direct-injection V-6s—a 3.0-liter and a 3.6-liter. While those engines will still be available in higher trim levels, the 2.4-liter I-4 will be standard on the CX model. GM plans on mating the engine to the same six-speed transmission used on the V-6 cars, allowing it to achieve 20 mpg in the city and 30 mpg on the freeway. (EPA certification is still pending.) That may not seem stellar, but it is an improvement over the 18/27 mpg city/highway posted by the front-wheel-drive 2010 Lincoln MKZ.
Although GM hasn’t yet released pricing information for the LaCrosse, we’d expect the four-cylinder model to be the value leader. Press materials claim the larger Acura TL is a competitor, but the advent of the 2.4-liter LaCrosse CX model also allows Buick’s latest offering to directly target Acura’s smaller TSX.
Expect both four- and six-cylinder 2010 LaCrosse models to arrive at Buick dealers later this fall.
