Vehicle Overview
For 2007, several new luxury features become standard on Buick's midsize sedan, including General Motors' OnStar Turn-by-Turn navigation system.

Three versions of the LaCrosse are offered — the CX, the midlevel CXL and the performance-oriented CXS — and two engine choices are available. Three levels of traction control, including General Motors' StabiliTrak electronic stability system, are offered. "QuietTuning" features include acoustical laminate on the windshield and front side glass and "Quiet Steel" laminate in front of the dash. The LaCrosse is the first Buick that can be equipped with both a factory-installed remote starter and remote-operated climate control.

Four new exterior colors are available in 2007: Midnight Blue Metallic, Stone Gray Metallic, Midnight Amethyst Metallic and Red Jewel Tintcoat. There is also a new steering wheel.

Buick's familiar elliptical vertical-bar grille is fitted on the LaCrosse, and it's flanked by dual headlights. Sculpted forms in the hood sweep back toward the windshield. Jewel-like headlights and taillights, along with chrome body accents, are installed. Amber side marker lights are integrated into the outer lenses, which taper into the front fenders. CXS models include projector fog lamps.

The LaCrosse has rear quarter windows in the C-pillars, which Buick says help reduce blind spots in the car. Rocker panels on CX models have a grained graphite finish, while those on the CXL and CXS have a glossy, body-colored finish. Chrome door handles are used on the CXS sedan.

The wheels measure 16 inches in diameter on the CX and 17 inches on the CXL and CXS. The CXS now offers 12-spoke chrome aluminum wheels or 12-spoke wheels. Ten-spoke flangeless chrome tech wheels are available on the CXL. A power sunroof is optional. Built on a 110.5-inch wheelbase, the LaCrosse is 198.1 inches long overall.

LaCrosse sedans come in either a five- or six-passenger configuration. Five-passenger models have a console-mounted gearshift lever and a center armrest. Six-passenger sedans have a column-mounted gearshift and a "flip and fold" seatback cushion that can double as an armrest and storage bin. A 60/40-split, folding rear seatback is standard in CXL and CXS models and optional in the CX.

Cloth seats are installed in the CX, while the CXL and CXS have leather seating surfaces. The steering wheel in the CXS has standard tilt and telescoping adjustments. Trunk capacity is 16 cubic feet.

Standard equipment includes PassLock III theft-deterrent system, remote keyless entry, a power driver's seat, power windows and locks, and a six-speaker stereo with a CD player. Heated seats, XM Satellite Radio, and auxiliary audio and climate controls on the steering wheel are optional.

Under the Hood
CX and CXL models use a 3.8-liter V-6 engine that produces 200 horsepower and 230 pounds-feet of torque. A 3.6-liter V-6 with variable valve timing goes into the CXS and delivers 240 hp and 225 pounds-feet of torque. Both engines team with a four-speed automatic transmission.

All-disc antilock brakes and side curtain airbags are standard, and GM's StabiliTrak and Ultrasonic Rear Parking Assist are optional.
