The Buick LaCrosse is a mid-size four-door sedan that has a foot in both the luxury and mainstream worlds. The base car is a mild-hybrid four-cylinder, the upgrade a powerful V-6. As such, and with optional all-wheel drive, the LaCrosse has among its rivals vehicles like the Lincoln MKZ, Volvo S60, Acura TLX, and Lexus ES.

One of the first vehicles to usher in the latest era of Buick style and size, the LaCrosse effectively replaced the old LeSabre sedan when it was new in 2005. That first version was quite different from today's car: it was much like a smaller version of the Lucerne, epitomizing the old American view of a floaty, conservatively styled luxury Buick. Powered by a 3.6-liter V-6, a 3.8-liter V-6 or a 5.3-liter V-8, the first-generation LaCrosse was neither sporty nor fuel efficient, though the V-8 model packed some solid highway muscle. In any of three trims--CX, CXL and CXS--the car was front-drive only and offered features that came up somewhat short of the competition.
To help remedy that problem, the Super trim was added in 2008, featuring magnetic adjustable shock absorbers, larger brakes, a revised suspension, projector beam fog lights, wood grain interior trim and new leather seating surfaces. The 2009 model year was the last for the first-generation LaCrosse.
The second-generation LaCrosse has been a completely different prospect, with a striking design and much-improved materials, build quality, features and ride. Introduced to the market in 2009 as a 2010 model, the new LaCrosse quickly garnered praise for its looks, and featured a new range of engines, including a 2.4-liter four-cylinder, a 3.0-liter V-6 and a 3.6-liter V-6. The four-cylinder was intended to grab great fuel economy figures for LaCrosse, while the 3.0-liter and 3.6-liter V-6s add some thrust to the large sedan.
Initially it was available in four trims--CX, CXL, CXS and AWD, and at first, the new LaCrosse was packaged to suit a variety of tastes and budgets. The base CX featured standard OnStar and the 255-horsepower 3.0-liter V-6 engine, with cloth interior, single-zone automatic climate control, and available entertainment and comfort & convenience packages. The CXL stepped up with dual-zone automatic climate control, heated seats, variable-effort power steering, and an available luxury package. The CXS added to this with the 280-horsepower 3.6-liter V-6 and memory-setting seats. The all-wheel-drive LaCrosse was only available in CXL trim, with the 3.0-liter V-6. All new LaCrosse sedans featured a six-speed automatic transmission.
GM discontinued the 3.0-liter V-6 in 2011, since the 3.6-liter six offered much better performance and gave equivalent real-world gas mileage. The bigger six remains the upgrade engine today.
In the same year, the 182-horsepower four-cylinder model became the LaCrosse's base engine. It was a stopgap measure, lasting just a year until the Buick LaCrosse eAssist was introduced in the 2012 model year.
With a reconfigured version of GM's belt-alternator-starter mild-hybrid system, the LaCrosse eAssist is now the base engine. It returns EPA ratings of 25 mpg city, 36 highway. With it, the LaCrosse has a smoother, more refined character than the old four-cylinder--thanks to the electric-motor system, which allows the engine to stop at stoplights (it's restarted when you lift off the brake).
The IntelliLink touch-screen connectivity system was new to the LaCrosse lineup for 2012 and combined phone and media-player connectivity with the capability to stream audio through Pandora or Stitcher apps; it was made standard for 2013. At the same time, Buick integrated the navigation system with IntelliLink, and topped off the GPS' features list with XM Travel Link services, including real-time traffic reports.
For the 2014 model year, Buick gave the LaCrosse a mild facelift, adding LED running lights and taillamps and reshaping the hood and dash. New interior trim options included an "Ultra Luxury" package with wood and lightly treated leather, while a new Bose audio system becomes an option. The powertrains were carried over, while 20-inch wheels and tires are a new option. The IntelliLink system also was upgraded to add more functionality--it can hold 60 user favorites, and 1000 contacts, and it now has the user-configurable home screen and other functions found in Cadillac's CUE system, minus the haptic feedback.
For 2015, the LaCrosse adds some modern technology that's becoming a necessity in its price class. A rearview camera is now standard on all LaCrosse sedans, and Buick's IntelliLink infotainment system can give directions to your iPhone through Siri Eyes Free. The LaCrosse now can also come equipped with a 4G LTE connection, which includes the ability to broadcast a WiFi data connection inside the vehicle.
