Wiesmann Sports Cars Receive New BMW Powertrain for 2011

Seeing as German sports car manufacturer Weismann relies on BMW for a number of components -- namely engines -- to build its range of retro-styled sports cars, it's not too surprising to learn the company's integrated some of Munich's latest mills into their portfolio.

Perhaps the most radical change lies with the MF 5 Roadster and Coupe. Both cars were previously powered by BMW's 507-horsepower, 5.0-liter V-10, which originally was found in the previous generation of the M5 and M6. Since production of both Bimmer models ceased earlier this year, supplies of the V-10 have dried up. Further muddying the waters is the fact that BMW also recently discontinued building its 367-horsepower, 4.8-liter V-8, which was used in Wiesmann's MF4 line.

The replacement for both engines lies with a BMW-sourced twin-turbocharged 4.4-liter V-8, albeit in very different tunes. When fitted in MF 4 models, the 4.4-liter pumps out 400 horsepower, just as it does when BMW nestles it between the fenders of the 550i and X5 and X6 xDrive50i. MF5 models, however, receive the 555-horsepower, M-tuned version of the same engine, which is presently offered in the X5 M and X6 M, and possibly under consideration for the next M5. Although both cars now have more power underneath the hood, their performance metrics remain essentially unchanged. MF 4 cars can sprint from 0-60 mph in 4.6 seconds and reach a top speed of 181 mph, while MF 5 models sprint to 60 mph in 3.9 seconds, and feature a top end of 193 mph.

The only Wiesmann model not receiving a new engine is the entry-level MF3. Remarkably, it continues to utilize the 3.2-liter inline-six-cylinder from the last-generation (E46) BMW M3, albeit the company notes it's now been tuned to bring the engine up to Euro 5 emission standards.

Although that revision allows Wiesmann to sell the MF 3 portfolio across Europe, the company still has no plans to modify or certify it's wares for consumption here in North America. Color us disappointed...
