Wiesmann Roadster MF4 Teased Ahead Of Geneva

Everyone's favorite family of retro-styled, BMW-powered roadsters is getting another member with the Wiesmann MF4 set to debut at next month's Geneva Motor Show.

From what we can tell from this sketch, the MF4 will look nearly identical to other Wiesmann Roadsters. So, we can only guess that the new stuff is happening under the hood. World Car Fans is speculating that motive power could come either from BMW's 367 HP 4.8-liter V8 or even the 420 HP 4.0-liter from the 2008 BMW M3. [via World Car Fans]
