Wiesmann MF4 and MF5 engine replaced with 4.4L twin-turbo V8 from BMW

The BMW V10 powering the Wiesmann MF4 and MF5 was recently killed off. So Wiesmann will replace it with a 4.4L twin-turbo V8, once again sourced from BMW.

In the MF4, the new engine puts out 407 hp, helping it achieve a 0-60 mph time of 4.6 seconds. The top speed’s not too shabby either, at 180.8 mph.

As for the MF5, the engine will be tuned to produce a solid 555 hp. This means 0-60 is dealt with in just 3.9 seconds, and it’ll soldier on to a top speed of 193.2 mph. This will be the most powerful Wiesmann ever made.

The 4.4L V8 also claims to be more efficient than the outgoing 5.0L V10, likely thanks to the smaller displacement coupled with forced induction and direct injection. While no fuel economy figures have been released for the MF4, the MF5 is said to use 10.7 litres of gasoline per 100 km, the equivalent of about 22 mpg.

The evolution of dynamics: The Wiesmann model series MF4 and MF5 as of now come with new twin turbo engines
Motor replacement at the Dülmen sports car manufactory. Starting in the new year, Wiesmann will be banking on BMW twin turbo technology for their model series MF4 and MF5. The Wiesmann GT and Roadster MF4 and MF5 can now be ordered with the new engine types. These engines will be stronger and more agile, while working more efficiently and economically than their predecessors. Top priority in the selection of these new engines went to what Wiesmann is all about: unlimited driving fun.

The MF4 will now be equipped with a BMW 4.4l V8 twin turbo direct injection petrol engine. With its engine capacity of 4,395 cm³ and 407 hp (300kW) at 5,500 to 6,400 rpm, the MF4 will reach a top speed of 180.8 mp/h. It will reach 0 to 60 mp/h in just 4.6 seconds. And while doing so, these handmade sports cars create an unrivalled symphony of sound, power and sheer driving excitement.

Also the MF5 will receive an engine based on latest twin turbo technology. The top-of-the-range model will also be equipped with a 4.4l V8 twin turbo direct injection petrol engine – this one, however, with even more impressive capacity. Here are the M-motor specifications: 555 hp at 5,750 to 6,750 rpm; 0 to 60 mph in 3.9 seconds, and a top speed of 193.2 mp/h. And all that with just 10.7l per 100 km (combined) – a truly remarkable result at such performance values. The new engines make the MF5 model series the most powerful Wiesmann cars of all time.

The Wiesmann Roadster MF3 will keep its current engine (now with Euro 5), leaving the classic roadster untouched for connoisseurs of the car manufacturer for individualists.
