The 2012 Buick LaCrosse will start at $29,960 plus an $860 destination charge, when it goes on sale later this year. The eAssist, which features a 2.4L four-cylinder and a mild-hybrid system, is priced identically to a V6 powered model, but can get 37 mpg on the highway, an impressive figure for such a large car.
Fuel economy in the city is estimated at 25 mpg, helped in part by regenerative braking and a start-stop system (the latter will be standard on all 2012 LaCrosse models), as well as low rolling-resistance tires, a 6-speed automatic gearbox and special aerodynamic modifications. The hybrid motor itself can produce 15 horsepower and 79 lb-ft of torque on its own.
On the downside, trunk space for the eAssist is reduced due to the trunk-mounted hybrid components, and weight is up by 65 pounds.
