Narrow year range (drag arrows to filter):
Extensively freshened, the LaCrosse sports a bigger waterfall grille, a new hood, and revised lighting with the option of bi-xenon HID adaptive headlights. The rear fascia has an integrated spoiler and wraparound LED taillights, and the interiors have been redesigned with upgraded materials, new seats, a new center control stack, updated telematics, and a posh new Ultra Luxury option.
After eAssist's debut last year, 2013 is quiet for the LaCrosse. Option groups are arrayed in five packages now (previously seven), ranging from the base LaCrosse to the Touring package, with Leather, Premium I and Premium II levels filling in. All-wheel drive (AWD) is available on Leather and Premium I trim levels.
The biggest change in the 2012 LaCrosse is standard eAssist, which marries an 11 Kw (15-hp) electric motor to a 182-hp 2.4-liter Ecotec four driving a six-speed automatic transmission. It's good for a 20-percent improvement in EPA highway fuel economy and an impressive 32-percent boost in city economy over the 2011 four-cylinder LaCrosse. If you prefer horsepower to hybrid power, a lighter and more powerful (than last year) 303-hp 3.6-liter V6 is a no-cost option.
For 2009, heated side mirrors are made standard on all models, while the CX trim has its wheel covers replaced by 16-inch painted aluminum wheels. Bluetooth hands-free phone communication is now optional across the line. The CSX trim has been discontinued.
Buick wants to appeal to younger buyers, and the 2015 LaCrosse sedan is at the forefront of that effort. It's handsome without being in-your-face about its styling, and it comes very well equipped even in base models. On the road, it's comfortable and quiet, with a pair of refined drivetrains to choose from: a 2.4-liter 4-cylinder with GM's "eAssist" mild-hybrid system, or a 304-horsepower V6. Conservatively handsome, well equipped, capable, quiet, comfortable, and refined, the LaCrosse presents well as a thoroughly credible alternative to import brands like the new Hyundai Genesis and Acura TLX sedans. You can even add the traction enhancements of all-wheel drive. This year, the Buick LaCrosse expands its technology portfolio as well, with 4G LTE and a wireless hotspot.
