2015 Buick LaCrosse

The Buick LaCrosse enters 2015 building on the momentum of comprehensive updates introduced the previous year -- attributes and features that helped it earn a Consumer Guide Best Buy award for 2014 -- adding greater technology through new OnStar with 4G LTE and standard built-in Wi-Fi hotspot, IntelliLink with Text Messaging Alerts and Siri Eyes Free.

The LaCrosse's appearance is instantly recognizable as a modern Buick, with light-emitting diode (LED) lighting elements that enhance its technologically advanced presence. The headlamp housings, for example, have a more angular appearance and LED signature accents. They are also positioned slightly outboard to reinforce the car�s presence.

LaCrosse's interior has a warm, inviting ambience and supports the integration of Buick's next-generation IntelliLink infotainment system. It also has a flowing, organic design that mixes contemporary colors, complementing trim and premium soft materials that reinforce Buick's attention to detail.

The LaCrosse is equipped with a choice of two efficient engines: the standard 2.4L four-cylinder engine with eAssist light electrification technology, rated at 182 horsepower; and an available 3.6L V-6 rated at 304 horsepower. Each is matched with a six-speed automatic transmission.

LaCrosse with eAssist uses a lithium-ion battery system and electric motor-generator to enable regenerative braking capability. Instead of providing all-electric propulsion, the system provides power assistance to the internal combustion engine. The eAssist system also allows the engine to shut down fuel delivery in certain deceleration situations, or at a stop, which saves additional fuel.

Buick's QuietTuning engineering process is standard on all models. It reduces, blocks and absorbs unwanted noise, making LaCrosse one of the quietest cars in the segment.
