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, Buick added the Super trim 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 end of the first-generation LaCrosse's run.
The second-generation LaCrosse was 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. It featured a new range of engines, including a 3.0-liter V-6 and a 3.6-liter V-6. A 2.4-liter four-cylinder was added in the second year of production to grab great fuel-economy figures for LaCrosse, while the V-6s were meant to provide some thrust for the large sedan.
Initially, the second-generation LaCrosse was available in the same CX, CXL, and CXS as the first generation. The base CX featured standard OnStar and a 255-horsepower 3.0-liter V-6 engine. The CXL stepped up with more equipment, while the CXS got the 280-horsepower 3.6-liter V-6. The all-wheel-drive LaCrosse was only available in CXL trim with the 3.0-liter V-6. All of these LaCrosse sedans featured a six-speed automatic transmission.
For 2011, GM axed the 3.0-liter V-6, leaving the more powerful and similarly efficient 3.6 as the lone step-up engine. It remains the optional engine to this day, now making 304 hp. In the same year, the 182-horsepower, 2.4-liter four-cylinder became the LaCrosse's base engine. It was a stopgap measure, lasting just a year until the Buick LaCrosse eAssist was introduced for the 2012 model year.
GM's eAssist four-cylinder is a mild-hybrid that makes use of a belt-driven starter/generator. It is more refined than the unassisted four-cylinder it replaced, provides more power and also returns better mileage figures, according to the Environmental Protection Agency: 25 mpg in the city and 36 on the highway. The electric motor allows the engine to shut off at stoplights and restarts it when you lift off the brake, and also provides some boost when accelerating. The four-cylinder engine is only available with front-wheel drive.
Buick's 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 the 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 SiriusXM Travel Link services, including real-time traffic reports.
For the 2014 model year, Buick gave the LaCrosse a mild facelift, added LED running lights and taillamps and reshaped the hood and dash. New interior trim options included an Ultra Luxury package with wood and lightly treated leather, while a Bose audio system became an option. The powertrains were carried over, while 20-inch wheels and tires were a new option. The IntelliLink system was also upgraded to add more functionality. Today's version can hold 60 radio and media presets and 1,000 contacts, and it has a user-configurable home screen and other functions found in Cadillac's CUE system, minus the haptic feedback.
The LaCrosse is offered with packages that carry no on-vehicle badging. There's the base LaCrosse, then a LaCrosse with Leather Group, LaCrosse with Premium I Group, and LaCrosse with Premium II Group. Each adds more equipment, while both of the Premium groups include the V-6 as standard equipment.
For 2015, the LaCrosse added modern technology such as a standard rearview camera and Siri Eyes Free to go with the IntelliLink system. The 2015 LaCrosse also added a 4G LTE connection, which includes the ability to broadcast a Wi-Fi data connection inside the vehicle for an extra monthly fee.
Upgrades for 2016 were minimal. They included a new eight-inch screen for IntelliLink with two USB ports and more intuitive controls.
The new Buick LaCrosse
A new LaCrosse is due in summer 2016. It gets an all-new platform and styling inspired by the Avenir concept that debuted at the 2015 Detroit auto show. The new car is marginally longer and lower than the 2016 model, but the wheelbase and front and rear track grow considerably, opening up more cabin space and giving the car a more stable footprint. It is 300 pounds lighter, thanks to more high-strength steel in the body and lighter but more effective sound deadening materials.
The independent rear suspension changes from a four-link to a five-link setup and the front suspension is MacPherson struts in lower end models and GM's Hyper Strut design in higher line versions. Adjustable dampers will also be offered.
Under the hood, the 2017 LaCrosse gets the latest version of GM's 3.6-liter V-6 making 305 hp and 268 pound-feet of torque and adding start/stop technology. The six-speed automatic transmission gives way to a new eight-speed that promises improved fuel economy. The eAssist mild hybrid, which is teamed with a 2.4-liter four-cylinder in the current car, does not return.
Inside, the 2017 LaCrosse is completely redesigned and features a new eight-inch center touchscreen with the latest generation of the IntelliLink infotainment system. This version uses fewer hard buttons and comes with Android Auto and Apple Car Play.
