The Wiesmann Roadster MF5 was introduced at the Frankfurt International Motor Show in 2009 and is the open-top variant of the GT MF5. Apart from the soft top, the bodywork has remained unchanged and all standard equipment has been carried over to the roadster, including dual airbags, ABS, and stability control. Additionally, the luggage compartment has been modified and an electrically operated rear spoiler has been added.
The Wiesmann Roadster MF5 is powered by a roaring BMW M-performance V10 engine that guarantees a hefty dose of adrenaline. After all, a Wiesmann handles like a go-kart and has no roof. With 507 hp (378 kW) and 520 Nm, it reaches a top speed of 310 km/h and sprints from 0 to 100 km/h in just 3.9 seconds.
