Bentley confirms diesel-powered Bentayga with electric turbo

Bentley has confirmed the new Bentayga off-roader that was presented last month at the Frankfurt Motor Show will become its first-ever diesel-powered model.

Peter Guest, the company’s head engineer, told trade journal Automotive News that the first diesel-powered prototypes are already undergoing shakedown testing. Guest didn’t provide specific technical details but he revealed that the oil-burning Bentayga will be fitted with an electric turbocharger, a technology that sister company Audi is currently developing.

Widespread rumors claim the Bentayga will use an evolution of the 4.0-liter TDI V8 engine that will power the upcoming Audi SQ7. The eight-cylinder will be tuned to generate approximately 435 horsepower and 730 lb-ft. of torque, though Bentley could raise those figures in order to widen the performance gap between the Bentayga and the SQ7. An automatic transmission will send power to all four wheels.

Although Bentley hasn’t revealed when the Bentayga diesel will be introduced, we wouldn’t be surprised to see it in the metal next March at the Geneva Motor Show. The entry-level model is being developed primarily for buyers in Europe, where gasoline is exceptionally expensive, and it’s unlikely to make the trip across the Atlantic.

What’s next?

At the other end of the spectrum, reports coming out of England claim Bentley is also developing a faster, more powerful version of the off-roader that’s tentatively dubbed Bentayga Speed. With well over 600 horsepower on tap, the Bentayga Speed will allegedly be capable of reaching 60 mph from a stop in less than four seconds.
