Imagine you owned a BMW M2 and the car’s abilities just doesn’t match up with your expectations. Maybe you just need to meet the fine folks over at Dähler Design & Technik GmbH. Instead of simply tuning the M2’s N55 3.0-liter inline six engine, Dahler is actually offering to take out the engine entirely and swap with the M4’s own S55 turbo six engine and then tuning the new engine to produce 531 horsepower and 538 pound-feet of torque with a top speed of 199 mph.

Exterior modifications on the BMW M2 are limited to a few aero bits and a new set of wheels. A black-trimmed bumper and side vents are the standard add-ons, but Dahler is also offering a front lip spoiler, a new rear wing, and a set of 20- or 21-inch staggered wheels as added options.


The program comes with interior upgrades, but Dahler didn’t disclose the specifics of what those upgrades are. The tuner only said that it can dress up the cabin depending on the request of a particular customer. 

Dahlia’s engine upgrades for the BMW M2 covers plenty of detail, in part because the tuner is offering a variety of programs for the compact performance coupe. First, there’s the N55 Competition Line, which is made up of three different stages, each with a specific increase in output.
