2013 Buick LaCrosse: Largely unchanged for the current model year, the 2013 Buick LaCrosse is a mid-size entry-level luxury sedan available with two different engines; a base 2.4-liter 4-cylinder engine and an optional 3.6-liter V6. The base engine produces 182 hp and 172 lb-ft of torque. Paired with a 6-speed automatic transmission the base LaCrosse achieves an EPA estimated 25 mpg city and 36 mpg highway. For increased performance Buick offers an optional 3.6-liter flex fuel V6 engine that yields 303 hp (paired to the same 6-speed automatic transmission). Available features include 19-inch wheels, halogen HID headlamps, heated-power adjustable mirrors, power sunroof, dual-zone climate control, premium audio system with navigation, hands-free phone capabilities, heated seats, and rear vision camera.

The LaCrosse is backed by a 4-year/50,000-mile warranty.
