The present generation Buick LaCrosse is a largeish sedan that blends modern styling with traditional Buick traits like easy steering and a cushy ride. The base engine pairs a 2.4-liter 182-horsepower four-cylinder engine with an 11-kilowatt electric motor. Fuel mileage estimates for this roomy sedan are almost 30 mpg combined. A 3.6-liter V6 with 303 hp is also available. A six-speed automatic is the transmission choice either way. Front-wheel drive is standard, though V6 buyers can also opt for an all-wheel drive version.
The second-generation LaCrosse debuted for 2010 and was offered in base CX, midlevel CXL and top-of-the-line CXS trim levels. Initially, there were two V6 engines offered: a 255-hp, 3.0-liter V6 and a 280-hp, 3.6-liter V6. The smaller V6 was dropped the following year and a new four-cylinder version was introduced.
The LaCrosse models sold prior to 2014 had slightly different exterior styling than the present models. Intellilink’s smartphone integration features as well as electronic safety features like lane change alerts and rear cross traffic alerts were unavailable prior to ’14.
The first-generation Buick LaCrosse was produced for the 2005-’09 model years. Its highlights were available six-passenger seating (with a front bench seat), a large trunk and quiet ride.
Like the second generation, there were three trim levels for most of the first generation LaCrosse’s run: CX, CXL and CXS. The CX and CXL were powered by GM’s venerable 3.8-liter, 200-horsepower V6, while the CXS got a 3.6-liter V6 good for 240 hp, and the Super had a 5.3-liter small-block V8 providing 300 hp. All cars were front wheel drive and featured a four-speed automatic transmission.
The CX came with basics like air-conditioning and full power accessories, while the CXL stepped up to leather upholstery, auto climate control and better exterior trim. The CXS added 17-inch alloy wheels, a sport-tuned suspension, a tighter steering ratio and a split-folding rear seat. The Super featured a powerful V8, a sport suspension, unique front and rear styling and dual chrome exhaust outlets.
