Buick LaCrosse's stiff body structure serves as the foundation for precise suspension tuning, safety and a quiet ride. Buyers can choose from a family of efficient, direct-injection six-cylinder engines and a fuel-conserving six-speed automatic transmission with tap-up/tap-down control.

The direct injection engines in the Buick LaCrosse create more power with less fuel and reduce vehicle emissions through greater combustion control - particularly cold-start emissions that are reduced by up to 25 percent.

The 2010 LaCrosse will be offered in three models - CX, CXL and CXS:

CX - equipped with a new 3.0L direct injection V-6, premium cloth seats and 17-inch wheels. The 3.0L engine generates an estimated 255 horsepower (190 kW) and 211 lb.-ft. of torque (286 Nm) and is mated to a six-speed automatic transmission.
CXL - also equipped with the new 3.0L direct injection V-6, adds leather-appointed heated seats, dual-zone automatic climate control, fog lamps, outside rearview mirror with LED turn indicators and puddle lamps, and 18-inch wheels. Intelligent AWD is available.
CXS - equipped with a 3.6L direct injection V-6; real-time active-dampening suspension; perforated, leather-appointed, heated and cooled seats, and chrome-plated 18-inch wheels (19-inch optional). The 3.6L engine, mated to a six-speed automatic transmission, generates an estimated 280 horsepower (209 kW) and 261 lb.-ft. of torque (354 Nm).
