Martin and Friedhelm Wiesmann continue to design and build some of the most beautiful coupes and roadsters on the planet. For the 2009 Geneva Auto Show, they're planning to present the latest addition to the range: the GT MF4-S.

To mark the 20th anniversary of establishing their factory, the Wiesmann brothers have tapped development partner BMW for a DOHC 4.0-liter V8 from the M3 and modified it to produce 414 horsepower. Wiesmann will offer 30 lucky customers the choice of a dual-clutch automatic or a six-speed manual.

Inside, the car will feature custom embroidery and special instrumentation.

The GT MF4-S will be followed by several other 'anniversary editions,' including a new V10-powered MF5-S. Stay tuned.
