BMW’s most powerful production vehicle will roar into U.S. stores in the second half of 2021.

The limited-production BMW M5 CS sedan starts at $142,995, including shipping. BMW declined to disclose how many units of the track-tuned car would be built but noted output is limited to the 2022 model year.

The new model is based on the 5 Series, a stalwart in BMW’s sedan lineup. With 26,785 deliveries last year, the 5 Series was the second-bestselling BMW sedan in the U.S., after the 3 Series.

The M version received an update in August that features new front and rear styling and a larger 12.3-inch touch screen information display.

Adding a special edition series late in a model cycle generates marketing buzz for the 5-year-old 5 Series platform and could boost sales on a profitable nameplate.

The BMW M5 CS delivers extreme performance while offering some of the utility of a four-passenger car.

It is powered by a 4.4-liter M TwinPower turbocharged V-8 engine that delivers 627 hp, an increase of 10 hp over the Competition model.

Carbon-fiber reinforced plastic, in the roof, front splitter, mirror caps and rear diffuser and spoiler, makes the CS model 230 pounds lighter than the M5 Competition and helps propel the sedan from 0 to 60 mph in 2.9 seconds.

The CS builds on the M5 Competition package’s chassis and suspension tuning: stiffer engine mounts than the standard M5 sedan, 10 percent firmer springs and 0.2-inch-lower ride height.

A Gold Bronze finish is applied to the rim of the grille, model badging and the 20-inch forged light-alloy wheels. The adaptive LED headlights feature L-shaped light tubes that illuminate in a racing-inspired yellow instead of the standard white. The interior is laid out in a four-seat configuration, with the driver and front-seat passenger having lightweight, heated and electrically adjustable M carbon bucket seats.

The 2022 M5 CS offers exclusivity with limited additional investment to the manufacturer, said Sam Fiorani, vice president at AutoForecast Solutions.

“With the new wave of electric vehicles pushing the envelope, traditionally powered performance vehicles, like the M5, need to step up their game with lighter bodies, all-wheel drive and even more power,” Fiorani said. “The sub-three-second 0-to-60 time puts the M5 CS into rarefied air among all four-doors.”
