Dahler has been offering power upgrades for the regular M2 for a few years now, and its portfolio has recently grown to include the hottest version of the sports coupe yet, the M2 CS, which also serves the swansong of the series.
With the Stage 2 tune installed, the output of the twin-turbocharged, 3.0-liter inline-six grows from 444 HP (450 PS / 331 kW) to 542 HP (550 PS / 405 kW), and peak torque stands at 545 lb-ft (740 Nm), up from 406 lb-ft (550 Nm). The top speed limiter is also removed, allowing the M2 CS to exceed 174 mph (280 km/h), but this option is only available for markets outside Switzerland.

For those who find 542 HP a bit too much for their M2 CS, Dahler is also offering the Stage 1 power upgrade. The 513 HP (520 PS / 382 kW) and 516 lb-ft (700 Nm) produced by the turbocharged engine are good enough to rocket it up to a top speed of 188 mph (302 km/h), as this version is offered with the removed V-max limiter as well.
There is no word on the new 0-60 mph (0-96 km/h) acceleration, but the stock M2 CS does it in 4.0 seconds when equipped with the six-speed manual transmission, or 3.8 seconds with the seven-speed DCT.
Dahler also offers a new exhaust system, coilover suspension and lowering springs for the M2 CS, as well as ultralight forged alloy wheels, measuring 9×20- and 10.5×20-inch front and rear, shod in Michelin tires and available in different shades.
For those who’d like to take their enhanced M2 CS to the track, Dahler has more parts in store, such as racing seats and a roll cage, although as far as pricing is concerned, those interested in the upgrades will have to reach out to the Swiss tuner.
