About the 2010 Buick LaCrosse
2nd generation (2010-2016), first year of the full redesign
Buick markets the 2010 LaCrosse as a premium sedan built around graceful styling, a quiet cabin, and modern comfort. The focus is not sharp-edged sportiness, but a calm, upscale driving experience with more design flair and technology than the old model. For most shoppers, the LaCrosse is a roomy comfort-first sedan meant to compete with near-luxury rivals by mixing Buick smoothness with a more modern look and feel.
The CX is the straightforward comfort trim, with a quiet cabin, automatic climate control, and a power driver’s seat. The CXL adds leather, heated front seats, and Bluetooth, while the new CXS pairs a stronger 3.6-liter V6 with ventilated seats, premium audio, keyless start, and rear parking sensors.

Frequently asked questions
Is the 2010 Buick LaCrosse fully redesigned?
Yes. The 2010 LaCrosse begins the model’s second generation with a new body, cabin, chassis, and engine lineup rather than a light update of the 2009 sedan.
How different is the 2010 Buick LaCrosse from the 2009 model?
The 2010 LaCrosse is substantially different from the 2009 model. It has a more upscale design, a quieter five-seat cabin with more rear legroom, new powertrains, a six-speed automatic, and all-wheel drive on some CXL models.
What engines are in the 2010 Buick LaCrosse?
The 2010 lineup includes a 3.0-liter V6 in the CXL and a stronger 3.6-liter V6 in the CXS. A 2.4-liter four-cylinder also joins the CX later in the model year, and all versions use a six-speed automatic.
Did the LaCrosse trim lineup change for 2010?
Yes. The CXS joins the lineup as the most luxurious and powerful trim, while the previous Super trim is dropped. The CX and CXL names continue on the redesigned car.
Does the 2010 Buick LaCrosse have all-wheel drive?
Yes. Some 2010 LaCrosse CXL models have all-wheel drive, a new option introduced with the second-generation redesign.
