We found the V6 engines motor along smoothly and quietly on the freeway yet offer good power, growling enthusiastically under hard acceleration. The 3.8-liter V6 that comes in the CXL is a reliable, cast-iron, overhead-valve engine that gets an EPA-rated 17/28 mpg and delivers strong low-rpm torque for good acceleration in on crowded, low-revving American roads. The sportier CXS features a double overhead-cam engine that revs more freely and produces more horsepower, making the LaCrosse more fun to drive while rating 17/25 mpg. The new Super V8 turns this Buick into a modern muscle car but is refined and quiet when cruising. The Super is EPA rated at 16/24 mpg.
Electronic features abound, making the LaCrosse a safe, all-weather family car with nice conveniences. Among them: a remote starting system that will work from up to 500 feet away, great on cold winter mornings; OnStar, which will dispatch emergency crews to your precise location if you have a wreck and don't respond to operators' calls; XM satellite radio to pick up CNN, Fox News, ESPN, or your favorite music; and StabiliTrak, which can help keep you from skidding off a slippery road. ABS and side-curtain airbags come standard. Next Page
