The direct-injection 2.4-liter Ecotec four-cylinder makes 182 hp and 172 lb-ft of torque. It's the third engine in the LaCrosse lineup, which also has a 3.0-liter V6 and a 3.6-liter V6.

The EPA estimates the four-cylinder LaCrosse will get about 20 mpg in city driving when paired with the six-speed automatic transmission.

Buick expects about 25 percent of customers will take the four-cylinder, which will be available on the CX trim.

On Wednesday, the LaCrosse was named as finalist for the North American Car of the Year award.

The destination charge is included in the base price.
