Next Wiesmann GT will likely get the same power plant as the upcoming BMW (F10) M5 - a 4.4 liter bi-turbo V8 engine producing 585 PS (578 bhp / 431 kW) and 720 Nm (531 lb-ft) of torque.

More spy shots from automaker testing at the Nürburgring circuit, this time of the next Wiesmann GT going through some hard basic training.

Wiesmann is a German specialty marque which sources its engines from BMW. Underneath that classically-styled long and curvaceous bonnet the GT is probably packing a bi-turbo V8 from BMW - likely the same 4.4 liter bi-turbo V8 power plant that will go into the next (F10) M5. That engine rates at 585 PS (578 bhp / 431 kW) and 720 Nm (531 lb-ft) of torque.

The new Wiesmann GT is expected to be lighter than the current model through a more advanced use of lightweight materials.

As for new design cues, we will have to wait for more of the camo to fall away from this speeding GT. But with Wiesmann's design, you always know what you're going to get.
