The 2018 model year Buick LaCrosse Avenir is the luxury version of the standard LaCrosse, coming with unique styling cues, more standard features, and premium materials.
Visual cues that differentiate the two are the meshed grille, lower bumper, rims, and foglight surrounds. Inside, Avenir-exclusive details include a Chestnut interior color theme, embroidered first-row headrests and Avenir-scripted sill plates. Features available on other LaCrosse models come standard on the Avenir, including a powerful 310-horsepower V-6, nine-speed automatic transmission, navigation and Bose Centerpoint Surround Sound premium audio, as well as a panoramic moonroof.

The third generation of the LaCrosse represents a step forward for the Buick brand as a luxury brand.
With the help of new technology, new materials and improvements in all sectors, it is closer to Lincoln and Lexus.

First of all, the look didn’t look outdated the moment it got out of the assembly line. It looks quite fresh and ready to receive the younger generation aboard. The triple-shields in the middle of the black, large, grille looked elegant, but not old-fashioned classic. The entire vehicle looked like it was designed by a designer who had graduated the college after the Iron Curtain fell. Even if the base of the vehicle was the same Opel/Vauxhall Insignia, the Buick specific design language is present everywhere, but in a modern way.

Inside, the cabin is spacious and features up to date modern equipment. The instrument panel has three round dials with a modern look. A long list of options was provided by the Buick, including 4G LTE in-car WI-fi, a head-up display, an 8” infotainment display, and Bose sound system, etc.

Under the hood, there was either a 4-cylinder mild-hybrid system or a V6 unit that offered 310 hp. For the four-pot engine and basic trim levels, the standard transmission was a 6-speed automatic, while for the top versions the 9-speed auto or 8-speed auto were standard.

The second generation of the Buick LaCrosse was introduced in 2009 at the North American International Auto Show in Detroit as a 2010 model.
It was more of a revolution than just an evolution of its predecessor. GM used the Epsilon II LWB platform for it, shared with other cars from the group such as the Opel/Vauxhall Insignia, Buick Regal, or Chevrolet Impala. GM completed the new design language with a new engine lineup that provided either more powerful or more fuel-efficient powerplants.

The angled, swept-back headlights with tight corners formed an aggressive look for the big Buick sedan at the front. The waterfall grille was already a common aesthetic concept for the American premium brand. On its sides, the sculptured beltline resembled some older vehicles from Buick’s lineup. In the back, the enlarged taillights cut a big chunk of the rear quarter-panels.

Inside, Buick emphasized the accent on technology and introduced a new infotainment system with an option for DVD-player for the rear seat passengers was available on the options list. Theaters seats inspired the elegant cabin with wide seats at the front and curved center console. GM enhanced the safety in the LaCrosse. Its adaptive headlights, which ensured 15 degrees illumination on curves, introduced more airbags for side protection.

Under the hood, GM installed a wide choice of gasoline engines paired exclusively to a 6-speed automatic gearbox. Power went to the front or in all corners for selected versions.

The Premium brand Buick replaced the Regal model with the new LaCrosse in 2004 as a 2005 model year.
It had two V6 engines and front-wheel-drive. Despite its 4-speed automatic transmission offered as standard, it was fuel-efficient and thus it was the first vehicle to receive the SULEV (Super Ultra Low Emission Vehicle) title in 2006. The standard options were generous, and even a six-seats version was available. The base engine had 200 hp from a 3.8-liter displacement, while the CXS (highest trim) had 3.6-liter displacement and had 240 hp. The latter also was mated to a 4-speed automatic transmission.

Inside the cabin, there was plenty of room due to its big, 2.8 meter (110 in) wheelbase. Another plus point for the vehicle was the overall rating received from the IIHS, which placed the car amongst the top of its class. The CXS also had leather bucket seats, but on both trim levels, the heated seats were an option.

In the last production year, 2008, the LaCrosse received the 5.3-liter V8 small-block engine called LaCrosse Super. It was the fastest series Buick ever produced, with a 0 to 60 mph (0- 97 kph) sprint time in 5.7 seconds and a top speed of 240 kph (150 mph). In December 2008, the LaCrosse was dropped from production.
