Spy Shots: Wiesmann prototype out for a spin – Click above for high-res image gallery

Wiesmann was in a bit of a pickle when BMW announced it was no longer producing its V10. In addition to the M5 and M6, the high-revving 10 was used to power the Roadster MF5 and GT MF5 and we assumed Wiesmann would make the switch to the new 4.4-liter twin-turbocharged V8 engine. We were right. What we didn't guess is that it would be sticking the new mill under the hoods of both the Roadster MF4 and GT MF4. The Wiesmann MF3 will retain its 343 horsepower six-cylinder engine.

No word yet on how much power the twin-turbo will produce when utilized with the MF4, but when stuffed into the engine bay of the MF5 it's set to produce 555 horsepower, allowing it to run from 0-60 mph in less than four seconds, hit a top speed of 193 mph and become the most powerful Wiesmann ever produced.

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.

      Gotta love that Gutter-Guard mesh grille.

      I still remember the first time I laid eyes on a Wiesmann MF3 all those years ago when Jeremy reviewed it for Top Gear. Broken heart knowing I'll never ever have one (even used) since we can't get it in America. Never quite recovered.

        I too long for a Wiesmann.

        Regarding the MF4 models, these will use the non-M version of the BMW 4.4L V8 turbo now found in the BMW 550i, 650i (soon), 750i, X5 50i and X6 50i, called the N63. It makes around 400hp in the BMW models, but could make slightly more in the Wiesmann. This makes sense since until now, MF4 models had still been using the outgoing naturally aspirated 4.8L N62 V8, which I'm sure BMW is eager to cease production of (as soon as Morgan and other hold-outs also switch to the new turbo motor).

        The MF5, of course, will get the 550hp+ S63 M version of the 4.4L V8. In fact, they'll probably get the version slated for the M5/M6 which is rumored to hit about 580hp.

        Personally though, I would still opt for the special MF4-S model over either of those two. That one gets the 4.0L naturally aspirated S65 V8 from the M3. Turbos are great, but I'll still take the high revving mill every time. :)

      this will dilute the charm
