The BMW M2 CS has proven to be a highly capable sports car, having recently lapped the Nurburgring faster than an Audi R8, Mercedes-AMG, and Pagani Zonda S. As standard, the BMW M2 CS uses the same 3.0-liter twin-turbocharged S55 six-cylinder engine as the M4 Competition producing 444 horsepower and 406 lb-ft of torque.

Having previously transplanted the M4 engine into the M2 Coupe, Swiss tuner Dahler has plenty of experience tinkering with BMW's S55 six-cylinder engine. Using this experience, Dahler has given the BMW M2 a massive power boost in its new tuning package to make one of the best BMW M cars built in recent years even better.

Dahler's modified BMW M2 CS is offered in two states of tune. In the stage 1 tuning kit, the power output increases from 444 hp and 406 lb-ft of torque to 512 hp and 516 lb-ft of torque by adjusting the ECU. As a result, the top speed increases from 174 to 187 mph. If that's still not enough power for you, the stage 2 upgrade increases the output to 542 hp and 545 lb-ft of torque.

Eventuri Carbon intake systems homologated by Dahler also increases the performance, while a stainless steel quad exhaust system with a front and rear silencer makes the S55 engine sound more aggressive.

The rear silencer can be combined with the standard tailpipes or Dahler's tailpipes available with 3.5-inch or 3.9-inch diameters.

To increase the agility of the BMW M2 CS, Dahler can install a custom coilover suspension system built by the tuner and a sports spring set that brings the car closer to the ground. Power is transferred to the tarmac by Michelin tires measuring 9x20 inches on the front axle and 10.5x20 inches on the rear axle, wrapped around lightweight 20-inch forged alloy wheels available in a variety of colors.

Inside, a roll cage and racing seats help make the BMW M2 CS more track-ready. Dahler hasn't released pricing details for its new tuning package, but you'll need to pay at least $80,000 for the BMW M2 CS donor car.
