Buick LaCrosse Will Get Turbo 4-Cylinder

GM’s interim CEO Fritz Henderson is starting to open up on some of the company’s fuel-efficiency plans and the future involves a pair of turbocharged four-cylinders.

The first turbo-four will be offered in the new Buick LaCrosse but won’t be available immediately. Currently the LaCrosse is slated to get a standard 3.0-liter V6 that makes 255hp thanks to direct injection. The larger optional engine is a direct-injection 3.6-liter V6 which makes 280hp.

It’s not clear what size or output the new turbo engine will provide but if the Envicta concept on which the LaCrosse is based it could be a 2.0-liter engine with 250hp and 220 ft-lbs of torque. It could, however, a a version of the Ecotec 2.4 or even a direct-injection version of the turbo 2.0-liter currently offered in the Cobalt SS.

This would fit in between the two V6 options, although it’s not clear that the 3.0-liter six would continue on past the introduction of the turbo-four.

Little more is known about the second turbocharged four-cylinder, which will sit as the base engine in the upcoming Chevy Cruz. It will be just a 1.4-liter four-banger and while actual output figures are not available they will likely be in the 150hp range.

Henderson also confirmed that the Corvette will live on in a V8 rear-wheel drive package. He did, however, reiterate the company’s position that the Pontiac G8 will not survive past 2010
