Both MF4 and MF5 models with get the 4.4 liter, twin-turbo V8 from BMW but in different power configurations - the MF4 will come with 407 PS (300kW) and the MF5 with 555 PS (408 kW).

As previously reported, Wiesmann has confirmed a new power plant for the MF4 and MF5 models.

Since BMW discontinued the V10 engine, which Wiesmann was sourcing from the brand, the German specialty marque decided to upgrade the engine offerings on both the MF4 and MF5 with two variants of BMW's 4.4 liter, twin-turbo V8.

The MF4 will now be fitted with that direct-injection, twin-scroll/twin-turbo V8 to the tune of 407 PS (300kW). 0 to 100 km/h comes in 4.6 seconds and top speed is 291 km/h (181 mph).

The MF5 will get the X5 M and X6 M treatment with the power plant now pushed to 555 PS (408 kW). It takes just 3.9 seconds for the MF5 to reach the 100 km/h mark from a standing start and top speed is 311 km/h (193 mph).

The Wiesmann MF3 will keep its current 6-cylinder power plant.
