With an estimated curb weight of 3520 pounds, the M3 CS-which comes standard with a dual-clutch transmission-is actually a little lighter than a base, manual-gearbox model.
The CS is the ultimate M3 with ramped up power and performance.
Powering the M3 CS from 0-62 in 3.9 seconds - and on to a top speed of 174mph - is a 460hp turbo-charged straight-six, putting out 443lb ft of torque. According to BMW, the M3 CS can get from 0-60 miles per hour in 3.7 seconds, which sounds about exactly right, considering the Comp Pack can do it in around 3.8-3.9 seconds and the CS is a bit lighter and more powerful.
Things like automatic climate control and a specially adapted Harman Kardon surround sound system are featured, along with standard an adaptive M suspension with Comfort, Sport and Sport+ drive modes..
Adding power and subtracting weight is a proven formula for more speed and the M3 CS should deliver.
To counter that rising performance tide, BMW has introduced the M3 CS, a faster, lighter, stronger M3 that has its sights set on mauling its prey.
The special edition model will be limited to approximately 1,200 units worldwide, with about 550 units heading to the U.S. Those interested in getting their hands on the BMW M3 CS can put their orders in starting May 2018.
The chassis also gets a few exclusive modifications like a lightweight double-joint spring strut axle at the front and a five-link axle at the rear.
Thanks to the use of carbon fiber-reinforced plastic (CFRP) in the roof, front splitter, "Gurney Flap" and rear diffuser, the M3 CS sheds 110 pounds compared to the standard M3.. These items contribute to a 10-kg weight saving over the regular M3. Despite its sporting nature, the M3 CS does still get nice features inside. Customers who don't want white can also choose from San Marino Blue Metallic, Lime Rock Grey Metallic, Frozen Dark Blue II Metallic or Black Sapphire Metallic.
Externally there are a number of changes over the standard M3, these include special edition light alloy wheels. These come wrapped in Michelin Pilot Sport Cup 2 tyres and house BMW M compound brakes, with carbon-ceramic items optional. Seats and door panels are finished in two-tone leather and Alcantara, while the vehicle also gets BMW's top specification infotainment and a Harman Kardon sound system.
