Buick is giving the LaCrosse sedan some notable updates and changes for the 2018 model year in the U.S. market. According to GM’s own dealer order guides, the 2018 LaCrosse is getting GM’s new 9TXX nine-speed automatic transmission, a new hybridized powertrain, plus new exterior colors and various accessories.
On the outside, the 2018 LaCrosse replaces four existing exterior colors with four new ones:
- Crimson Red Tintcoat
- Dark Sapphire Blue Metallic
- Graphite Gray Metallic
- Dark Forest Green Metallic
- Satin Steel Metallic
- Black Cherry Metallic
- Dark Slate Metallic
- Red Quartz Tintcoat
The biggest change is the deletion of the eight-speed automatic transmission and its 3.08 axle found in the 2017 LaCrosse. In their place are GM’s new 9-speed transmission (M3G) with a 2.90 axle.
What’s more, the premium full size sedan gets an addition to its powertrain in the form of an optional hybrid drivetrain. The hybrid system consists of three components: a new 2.5L four-cylinder engine with direct injection and variable valve timing (LHN), a 6-speed automatic transmission (MNH), and a parallel hybrid electric propulsion system rated at 20 kW (HP5). The powertrain is available exclusively on the front-drive Preferred (1SB), Essence (1SB) and Premium (1SP) trims and brings with it a 2.64 axle and brakes that are an inch smaller in the front (16″ front and rear) compared to non-hybridized models. What we don’t know is how Buick will refer to models with this powertrain, with some obvious choices being LaCrosse eAssist, which it used on the second-gen LaCrosse, or LaCrosse Hybrid, a name used in China.
There’s also a host of new LPO-level (dealer-installed) accessories, including a cargo net, body-color grille, wheel lock kit and tire inflator kit.
The 2018 model year represents the second year of the third-generation Buick LaCrosse, which launched for the 2017 model year.
