The Bentayga is an important car for Bentley as it’s the first SUV produced by the VW-owned luxury automaker which they’re hoping will open the wallets of new customers who’d otherwise not consider one of their cars.
Being under the Volkswagen Group does have its perks. For example, Bentley saved themselves the effort of developing it from scratch by leveraging their MLB platform shared by the new Audi Q7 and upcoming Porsche Cayenne.
In addition to the current introductory variant and its 6.0-litre twin-turbo W12 engine, Bentley will reportedly be offering the Bentayga as a plug-in hybrid – a first for the company – and, now, perhaps even as a diesel – another first. To that end, it seems that the brawny 4.0-litre V8 turbodiesel with new e-turbo tech (electrically-powered compressor to eliminate turbo lag) will be called up for duty, according to Automotive News.
The engine made its debut in the Audi SQ7 TDI and produces 324kW and a massive 900Nm of torque, more than ample to handle any needs that the Bentayga might need it for. The unique turbocharging system piggybacks off the car’s 48-volt electrical system, using an electric motor to spool up the turbines at any engine speed, wiping out turbo lag while also increasing efficiency.
Bentley will likely be introducing this diesel-powered Bentayga variant over the course of the next year but with some likely performance tweaks to differentiate the powerplant from the one used in its Q7 sister car.
In addition to the trick oil burner, the Crewe-based automaker will also probably introduce more petrol engines into its new SUV. The 447kW 6.0-litre W12 engine can be pushed further still and will likely see use in the faster Bentayga Speed while a twin-turbo 4.0-litre V8 petrol engine (from the Continental GT V8) could be introduced in an entry variant.
