Not just any diesel, but the trick new 4.0-liter V8 from the Audi SQ7 TDI with its twin turbochargers and electric compressor. In the Audi, it produces a solid 435 horsepower but an insane 664 lb-ft of torque. But Bentley could tune it to produce even more when the diesel Bentayga hits the market sometime next year. One way or another, it would be the first diesel engine ever offered in a Bentley.
The diesel isn’t the only engine option said to be slated to join the Bentayga range. A more powerful Speed version could be based on the same 6.0-liter twin-turbo W12 as the current model, but with yet more oomph. (The current Continental GT Speed already packs 626 horsepower.) The Continental’s gasoline V8 could also be on offer as a lower-cost, lower-weight alternative to the big twelve. And a hybrid version remains a possibility.
