BMW recently shot down reports it was considering chopping the roof of the M2. Purists rejoiced. Posers were pissed. And tuner's got to work. Swiss outfit Dahler Design & Technik appear to be the first to introduce a BMW M2 convertible, a project that's a year in the making. Adding weight and compromising structural rigidity are the primary reasons why the M2, a car built for track-going enthusiasts, would only ever have one body style. Dahler is well aware of these issues, which is why it gave its open-top M2 comes more power, among other things.

Two states of tune are on offer, one that lifts the output of the twin-turbo inline-six from 365 hp and 369 lb-ft of torque (with overboost) to 402 hp and 427 lb-ft of torque, while level 2 gives the baby-M 419 hp and 450 lb-ft, and the ability to clock a sub-four second 0-62 mph time and hit a 187 mph top speed. A stainless-steel exhaust system provides a throatier soundtrack, although a silencer is also on offer to keep things respectable. A new adjustable coil-over suspension can be adjusted to suit, and also lowers the M2, while a high performance brake system with massive 400 mm discs will keep drivers honest. Other mods include a set of CDC1 wheels staggered 20/21 inches front/rear, an MID display unit and a bespoke interior upon request.

There's no word on how much Duhler wants for its BMW M2 cabrio, but it did reveal that it would be delighted to fit a S55 engine from the M4 in case customers wanted "the pure enjoyment of fresh air with even more understatement." Any takers?
