BMW shows off the M4 CS Lime Rock Grey

For the first time since its introduction last month, the upcoming BMW M4 CS is shown in the Lime Rock Grey color. There are also colors specific to the BMW M4 CS as factory colors, not Individual options.

The first is the San Marino Blue Metallic, as shown in the pictures and was a popular Individual color on the standard car. There’s also a Lime Rock Grey Metallic and a very special Frozen Dark Blue II, the latter of which is a matte finish and will only be available on a limited number of cars. BMW M4 CS Lime Rock Grey likely takes its name after the famous Lime Rock Park, the historic motorsports venue in Lakeville, Connecticut.

The BMW M4 CS sits right smack in the middle of the M4 Competition Package and M4 GTS, filling up a small nice in the M lineup. It manages to blend some of the hardcore performance of the M4 GTS with the everyday usability of the standard M4 Competition Package but, to be honest, seems like it will be better than both.

Design wise, the BMW M4 CS gets a Competition Package which adds some more extreme aero, wheels and body bits from the M4 GTS. For instance, the BMW M4 CS gets the same carbon fiber hood as the GTS, except its painted to match the body color. It also gets a unique fixed front lip spoiler in carbon fiber, which is a lot smaller than the one on the GTS, so there’s no fear of scraping it over the tiniest of bumps. At the back, there’s a small carbon fiber decklid spoiler, OLED taillights and a carbon fiber rear diffuser.

It also gets the new Style 763M wheels which debuted on the M2 and M3 at the 2017 NYIAS. The new wheels are 20″ at the rear and 19″ at the front, weighing in at just 10 and 9 kilograms each, respectively. They also come wrapped in Michelin Pilot Super Sport Cup 2 tires as-standard.

Inside, the BMW M4 CS gets some GTS treatment as well as some of its own design bits. The naked carbon fiber door panels and door straps are pulled from the GTS but the rest of the car is unique to the M4 CS, like the alcantara steering wheel with center line and a unique “CS” logo embroidered into the alcantara dash trim.

Under the hood lies a variant of the M4’s S55 3.0 liter twin-turbocharged I6 engine that now makes 460 hp and 442 lb-ft of torque for CS-duty. That extra power is created via tuning and not with water-injection like on the M4 GTS. While the M4 Comp Pack is available with a six-speed manual or seven-speed DCT, the M4 CS is only available with the DCT.

BMW tested the M4 CS extensively on the Nurburgring and it apparently clocked a time of 7:38, which puts it right in between the M4 GTS and standard M4.
