Bentley Bentayga to come with diesel engine

Bentley has confirmed that it will produce its first ever diesel powered vehicle in the Bentayga. The Bentayga was launched at the Frankfurt Motor Show last month. Peter Guest, the company’s head engineer said that the first diesel-powered prototypes are already undergoing shakedown testing and it will also feature an electric turbocharger. Currently its sister company, Audi is developing this piece of technology.

Electric turbocharging for the Bentley Bentayga diesel will mean no turbo lag – with power expected to come on stream from not much more than 1000 rpm – as much as 450bhp and a wave of torque that is expected to be more than 600lb/ft. Which should be enough to make even the gargantuan Bentayga feel nimble.

E-charging has been made possible thanks to the introduction of the 48-volt electric system in the Bentayga. The more powerful setup is needed to supply the 7 to 8 kilowatts of power the e-charger needs and also is used for the car’s “active roll control” dynamic ride system that can decouple the anti-roll bars for a smoother ride. “We needed 48V to get the reaction times [for the dynamic ride system],” Bentley sales head Kevin Rose said at the Frankfurt show

Brand purists will scoff at the idea of a diesel-powered Bentley. To keep them happy, the Volkswagen-owned automaker is also developing a more powerful, range-topping version of the off-roader tentatively dubbed Bentayga Speed that will reportedly be capable of reaching 60 mph from a stop in less than four seconds.

The traditional Bentayga is powered by a revised 6.0-litre W12 engine which was showcased at the Vienna Motor Symposium. The power output will be a hefty 542bhp and 700Nm of torque capable of propelling it to 100 kph in under 5 seconds. Considering the weight of the car this is a very significant number. The top speed on this machine is going to be about 300km/h.
