Sportscar manufacturer Wiesmann has revealed its latest GT – the 507bhp MF 5.

The German tuners have raided the BMW parts bin and fitted the M Division’s storming 5.0-litre V10 engine and seven-speed auto box found in the M5 and M6.

This means the baby GT sprints to 62mph (100 kph) in a hair-raising 3.9 seconds.

And although official figures haven’t been released, expect a top speed of 205mph.

Wiesmann has also fitted BMW’s Dynamic Stability Control (DSC) system to ensure the engine’s massive pulling power doesn’t overwhelm the 19-inch wheels.

The enormous V10 engine is mid-mounted in a bonded and riveted aluminium monocoque shell, with carbon-fibre reinforced body panels.

Inside, the driver is surrounded by leather and held in place by specially sculpted bucket seats.

The Wiesmann GT MF 5 will go on sale in spring 2008 with an expected price tag of €178,900 – just under £125,000.

But this isn’t the only car to benefit from the M5’s glorious free-revving V10 – German tuner Hamann has shoehorned an uprated version of Munich’s baby into the new 3 Series.

And the result is astonishing – 560bhp and a top speed of 208mph.

The ‘Thunder’ dispatches the obligatory 0-62mph dash in just 4.3 seconds – half a second quicker than the all-new M3.

As part of the ‘Thunder’ package, Hamann also offers 20-inch lightweight forged wheels, uprated brakes, a front spoiler and rear diffuser.

The entire package can be fitted to any new 3 Series coupe, from the 325i upwards to the M3.
