The 2010 Buick LaCrosse offered two V6 engine options: a 3.8-liter V6 and a 3.6-liter direct-injected V6. This combination gave buyers a choice between a familiar, smooth-power option and a more modern, efficiency-focused powerplant.
In 2010, Buick aimed to blend refined highway manners with premium comfort in the LaCrosse, and the two V6 engines were selected to support that goal. Below is a breakdown of the engine options available for this model year.
Engine options for the 2010 LaCrosse
The following engine choices were available across various trims and configurations of the 2010 LaCrosse.

3.6-liter direct-injected V6 — A more modern powerplant featuring direct injection (and typically variable valve timing) for stronger acceleration and improved efficiency, also paired with a six-speed automatic transmission.
These two engines offered a choice between a familiar, comfortable ride and a newer, more efficient option without sacrificing Buick’s emphasis on quiet, smooth operation.
