At the heart of the engine, nestled in the "V", are sequential turbochargers, with an electric compressor taking up the initial strain and covering any noticeable turbo lag.
Bentley is the first to admit that "Diesel" and "Bentley" are not two words you'd often put together, but the brand has thought long and hard about this move, waiting until it had the right engine in its paws, but "we now have the right engine and the right car. It has to fit within a Bentley context", we were told at the launch.
And that right context is a wave of torque at low throttle responses, that fits with a luxury model.
The Bentayga, like the Cayenne for Porsche, has been a runaway success. Bentley had planned 3,600 cars for the first year of production but has already built 3,300 and is predicting 5,000 sales by the end of the year.
