A few months back following the debut of the 2010 LaCrosse, Buick surprised us with the announcement that it would add a third powertrain option to the sedan's lineup. After launching with a pair of V6 engines, Buick is now getting ready to start offering a LaCrosse CX model with a 2.4-liter four-cylinder engine. This is the same direct injected unit that debuted in the new Chevrolet Equinox and GMC Terrain last summer.
When the four-pot LaCrosse goes on sale early in the new year, it will carry a base sticker price of $26,995 (*including delivery). That's $840 less than what it takes to get the current 3.0-liter V6 powered CX model in your driveway. In addition to the up-front savings, buyers should expect reduced operating costs for the four. Final EPA certification numbers aren't in yet, but Buick is estimating that the LaCrosse four will net 20 mpg in the city and 30 mpg on the highway. For comparison's sake, the 3.0-liter is rated at 17/26 mpg city and highway.
The new 2.4-liter LaCrosse is slated to arrive in dealers in the first quarter of 2010. Official details in the presser after the jump.
