The first all-new Bentley Continental GT in 15 years is undergoing final preparations...

Spotted doing its best impression of a Porsche 911 at the Nurburgring, this Conti mule is sporting Bentley's new W12 engine which debuted in the Bentayga--but good luck hearing it over the tortured tires screaming for mercy.

The new Continental GT will share the VW Group's MSB platform with the second-generation Panamera which is expected to help the big GT dip below the 5,000-pound mark.

Look for Bentley's latest to debut at the Frankfurt Motor Show this coming September.
