It looks like Bentley chief Franz-Josef Paefgen is being over-ruled when it comes to what kinds of powertrains will appear in his cars in the future. Specifically, Volkswagen is firmly committed to diesel engines while Paefgen has said that they are inappropriate for Bentley automobiles. VW Group CEO Martin Winterkorn told Auto Motor und Sport that the company will respond to changing markets and he could imagine a diesel Bentley. The engine for the British luxury brand is likely to be a new twin turbocharged variant of the current 3.0L TDI V6 currently being developed by Audi engineers. That engine with over 300 hp and 440 lb-ft of torque is set to debut in 2009 in the new A8. A high torque engine like this would be a good choice in a Bentley.
