The LaCrosse replaced the Buick Regal in 2005 and hasn't changed much since. This midsize four-door sedan can be purchased as either a five- or six-passenger vehicle, and it represent a step forward for Buick. While the front end features a larger version of the traditional Buick elliptical grille, several details are modern enough to show the LaCrosse is clearly a vehicle of the 21st Century. Tolerances between body panels are tighter than any previous Buick, and the four headlights are nicely framed by the sculpted hood. The LaCrosse is available in three trim levels. Like the CXL, the CX is powered by the venerable 3.8L V6. This elder statesman of the GM engine family makes 200-horsepower and 224 lb-ft of torque. The CXS is the performance model, and it comes equipped with a more modern 3.6L V6. This powerplant has double overhead camshafts and four-valves per cylinder. It pumps out 240 horsepower, and 90% of its 225 lb-ft of torque is available between 1,900 and 6,000 rpms. Notable standard equipment on all trims includes traction control, four-wheel disc brakes, power seats and windows, remote keyless entry, and air bags all around. The CXL is equipped with leather seats, memory features, automatic climate controls, a driver information system, among other items. Standard equipment in the CXS includes XM satellite radio, fog lamps, four-wheel independent suspension, and dual exhaust. Remote vehicle start, a six-disc CD changer, a heated driver seat, and a sunroof can be added to all LaCrosses. A Driver Confidence Package is available on the CXL and CXS, and it adds steering wheel-mounted controls, a universal home remote, heated mirrors, rear parking assist, and an electrochromic rearview mirror. StabiliTrak is an available option on the CXS. The newest Buick excels in its quiet, comfortable ride. Without a doubt, this is the best handling Buick we've ever driven. Buick engineers have gone to considerable effort to cut down on all the sources for road noise, and their hard work shows.
