dAHLer Does A G80 M3 CS Tastefully

The Stage 1 tune ups the power by 80hp and torque by 90Nm.

Time and again, dAHLer has proved that when it comes to tuning up BMWs, the team can dish out fantastic performance machines. An example would be the BMW M8 Cabriolet, which recently received the tuner’s Competition Line treatment. That was a specimen of a mass-produced model. The approach changes when a limited-run derivative rolls into the playing field. Meet dAHLer’s take on the G80 BMW M3 CS.

Although the four-door go-fast sedan also has ‘Competition Line’ in its description, the end product doesn’t look all that different from the original. That’s because the tuner respects the limited-run story by maintaining as many original parts as possible.

Under the bonnet is the original 3.0-litre twin-turbo inline six-cylinder engine. However, courtesy of dAHLer’s Stage 1 tune-up, the output has risen from 550hp/650Nm to 630hp/740Nm. A carbon fibre intake system is also part of the upgrade. The tuned-up sedan complies with Euro 6d-TEMP emission norms and comes with EU/CH homologation certificates.

The specimen presented here features the titanium exhaust system that BMW offers as standard. Those seeking a more theatrical soundtrack can opt for the stainless steel exhaust system with bi-flap control. That can be finished with 100mm or 108mm ceramic-coated tailpipes.

The car also dons the original wheels, spanning 19 and 20 inches in diameter at the front and back, respectively. dAHLer has added wheel spacers, which help align the rims with the fenders. Alternatively, one could order the 21-inch CDC2 forged wheels, designed specifically for the G8x series, from dAHLer. The ride has also been dropped, courtesy of the adjustable performance coilover suspension by the Belp-based tuner. If that’s a bit too sophisticated, dAHLer offers its own set of sports springs for the M3 CS. Those drop the ride height at the front and back by 24mm and 3mm, respectively.

dAHLer says all these upgrades can be applied to the standard M3 and M4 models. But the question is – do you like what the Swiss tuner has done here?
