Wiesmann has officially announced that it will succeed the BMW M5-sourced V10 powerplant it uses in its MF5 roadster and coupe with BMW's new twin-turbo 4.4-litre V8.
This is 'shock - night follows day' stuff, mind you - we predicted the news back in August, upon hearing of the demise of BMW's naturally aspirated V10.
The MF4 is also getting the new engine, however: the old 362bhp 4.8-litre V8 is being replaced with the 4.4-litre bi-turbo motor in a 402bhp state of tune. That's enough, says Wiesmann, to get the MF4 to 180mph, and to 62mph in 4.6secs.
At the top end of things, the MF5 is getting its V10 replaced with the M version of the same twin-turbo V8. This means 547bhp, 0-62mph in 3.9secs and a top speed of 193mph.
At the bottom end of the Wiesmann scale, the MF3 retains the same six-cylinder engine.
