Debuting today at the Madrid International Auto Show, the BMW M4 CS is a limited-run special edition that bridges the gap between the regular M4 Coupe and the hardcore M4 GTS. While the latter is limited to 700 units sold worldwide, the Spain-only CS will be offered in 60 units at €132,900 a pop, making it substantially more expensive than the regular M4 which kicks off at €92,099.

So, what do you get for paying an extra €40,800? BMW’s engineers fiddled with the turbocharged 3.0-liter inline-six engine and squeezed an additional 25 hp for a grand total of 450 hp. As it’s the case with the M4 GTS, output is delivered to the rear wheels with help from a seven-speed, dual-clutch gearbox.

Compared to the cream-of-the-crop M4 GTS, the more civilized CS comes with rear seats, so it’s not as light. On the other hand, it does have the carbon ceramic brakes of the GTS which shave off 30 pounds (13.5 kilograms) compared to the ones fitted on the standard M4 Coupe. BMW Spain isn’t saying a word about the car’s weight, but it’s obviously somewhere between the M4 (3,505 lbs / 1,590 kg) and the M4 GTS (3,328 lbs / 1,510 kg).

BMW Spain will sell the M4 CS with standard 20-inch alloys sourced from the GTS, but this time around with a silver finish. All cars will have the adaptive M chassis and differential as standard, along with some M Performance body add-ons dipped in carbon fiber like the front spoiler lip, rear wing, mirror caps, side skirts, and rear diffuser.

Customers will be able to order the M4 CS with a Brilliant White, San Marino Blue or Jerez Black paint and each will be combined with a different cabin theme. All cars will share a carbon fiber interior trim and are going to be offered with plenty of optional kit, including an upgraded sound system and a head-up display, among others.

BMW Spain will open the order books for the M4 Competition Sport in the near future.
