A Bentley engineer has confirmed that the upcoming diesel-powered variant of the Bentayga SUV will utilise electric turbocharging.

Bentley will borrow the technology from sister company Audi which will debut the technology on the high-performance SQ7 launching sometime next year. It remains to be seen just when the diesel Bentley Bentayga will be introduced but the company’s lead engineer Peter Guest confirmed to Automotive News that prototypes have already began testing the engine.

At this stage, no further details about the diesel Bentayga are known including the displacement or just how many cylinders the car will have. With that being said, it has been confirmed that the SQ7 will use a 4.0-litre V8 with electric turbocharging so there’s certainly a possibility the diesel Bentayga will use exactly the same engine. In the SQ7, it is tipped to produce 428 hp and 626 lb-ft of torque.

The entire premise behind electric turbochargers is that they completely eliminate lag to dramatically improve throttle response. This is achieved through the use of an electric motor which spins up the turbo before the hot exhaust gases are funnelled into it. This basically means the turbo is always spooled up.
