Why it stands out

The 2018 Buick LaCrosse stands out as a large, quiet sedan that leans into comfort rather than flash. It returned to full-size roots with sleeker, sportier styling, and it came standard with a 3.6-liter 310-horsepower V6, an eight-speed automatic, and front-wheel drive. All-wheel drive remained optional, and the chassis was shared with the Chevrolet Impala. On the road, that combination gave the LaCrosse a more relaxed, upscale feel than its price might suggest, while the available Dynamic Drive Package helped make the 2017 model surprisingly pleasant on back roads.

Inside, the LaCrosse aimed for a modern, roomy atmosphere with a “waterfall” center console, a larger 15-cubic foot trunk, and a bigger back seat. It also offered features such as a rear window shade, ventilated front seats, a head-up display, wireless phone charging, and a partially digital instrument panel. For 2018, Buick brought back eAssist on the 2.5-liter four-cylinder engine for 35 mpg highway, and the V6 was paired with a nine-speed automatic transmission. The Essence trim was also available with all-wheel drive, broadening the car’s appeal for buyers who wanted a more traditional Buick sedan with added traction.

The main drawbacks were price and some cabin materials. The LaCrosse was very pricey when new, with base, Essence, and Premium trims ranging from $33,000 to nearly $47,000, and the interior included a lot of flimsy plastic parts. Even so, its quiet ride, comfort, and available mild hybrid technology made it attractive to shoppers who valued a plush, low-key sedan over image or driving excitement.
