Bentley has published footage from high-speed testing of its new Bentayga SUV which seemingly confirms it will be the world’s fastest SUV.

Powered by Bentley’s new-generation 447kW/900Nm 6.0-litre twin-turbo W12, the Bentayga manages to assault physics by blasting its bulk to over 300km/h.

This puts clear air between it and existing rivals like the Porsche Cayenne Turbo S and Range Rover Sport SVR, though the Bentley off-roader is expected to be significantly more expensive than either.

Impressive as it is from an engineering perspective, we can’t help but feel that the Bentayga’s hig-speed ability is of little relevance on anything other than the spec sheet.
