2012 Buick LaCrosse (photos)
Buick bills its new LaCrosse as the most fuel-efficient luxury car with good reason. Its electric-assisted four-cylinder engine gives the full-size sedan average fuel economy around 30 mpg.

When GM thinned out its herd in 2009, Buick was one of the surviving brands. Buick models now represent luxury cars without the sport capability for which Cadillac has become known. The LaCrosse is Buick's full-size sedan.
Buick maintains a cohesive design language for its cars, with a rounded roofline and a toothy grille.
The base engine in the new LaCrosse is a direct-injection 2.4-liter, assisted by a small electric motor. A 3.6-liter V-6 is also available.
Buick keeps the interior design simple, with buttons confined to the head unit and just a few other areas.
Buick uses an electrically boosted power steering system, tuned for ease of turning rather than a lot of driving feel.
The tachometer shows an auto stop area, for when the engine shuts down at traffic stops.
Buick has a very cool new infotainment system called IntelliLink, but it is not available when the navigation system is present. Buick still needs to integrate these systems.
The navigation system's maps, stored on a hard drive, look very good. They also show some rendered landmark buildings.
Buick's Bluetooth phone system is not as advanced as others, for example requiring manual phone book entry.
The LaCrosse's audio sources include iPod, onboard hard drive, and satellite radio. There is no Bluetooth streaming audio.
The terrestrial and satellite radio screens let you save six sets of six preset stations, and you can mix and match AM, FM, and satellite.
The premium Harman Kardon audio system delivers very good quality sound, but strong bass will shake it up.
