The LaCrosse is available in four front-wheel drive trim levels - CX 4-cylinder, CX, CXL and CXS - as well as a new all-wheel drive CXL trim. New for 2010, the CX 4-cylinder gets a smaller, more fuel-efficient 182-hp 2.4-liter engine. The CX and CXL front-wheel drive models are powered by a 255-hp 3.0-liter V6 engine (rated at 252 horsepower on the all-wheel drive CXL), while the CXS is equipped with a 280-hp 3.6-liter V6. All three engines feature direct fuel injection, and are mated to a six-speed automatic transmission with Driver Shift Control manual shift mode. The CX trims are outfitted with 17-inch wheels, automatic climate control, satellite radio, MP3 capability and a power driver's seat; CXL trims add 18-inch alloy wheels, front fog lights, heated front seats, leather upholstery and Bluetooth wireless connectivity. The CXS boasts exclusive features that include distinctive 18-inch chrome wheels, ventilated front seats with memory, E-Z Key passive entry, upgraded harman/kardon audio with USB port, a heated steering wheel and a power rear window sunshade. A new hard drive-based navigation system is available on all but the CX trims, featuring 10 gigabytes of dedicated media storage, DVD video capability and a rear back-up camera. Standard safety features on every LaCrosse include 4-wheel anti-lock brakes with brake assist, StabiliTrak electronic stability control, traction control, and front, side-impact and overhead curtain airbags; CXS trims add rear parking assist (optional on the CXL). The Buick LaCrosse is completely redesigned for 2010, with new direct gasoline injection 4-cylinder and V6 engines, new six-speed automatic transmissions with Driver Shift Control, fresh exterior and interior styling, and additional standard and optional equipment. Additionally, the CXS replaces the Super trim from the previous model year.
