Under the bonnet, the Bentayga Diesel features a 4.0-litre V8 engine assisted by two sequential twin-scroll turbochargers and an electric supercharger running off a 48V power system.
The 'triple-charged' V8 diesel develops 320kW of power between 3750 and 5000rpm, and 900Nm of torque from 1000 to 3250rpm. The V8 engine drives all four wheels via a standard eight-speed automatic transmission.
Claimed to be the world's fastest diesel crossover, the Bentayga Diesel has a 0-100km/h time of 4.8 seconds and a top speed of 270km/h.
Under the EU testing cycle, the 2390kg Bentayga Diesel has a fuel economy rating of 7.9L/100km. Equipped with an 85 litre fuel tank, the oil burning Bentayga is said to have a range of around 1000 kilometres.
This engine seems to be same as the 4.0-litre V8 unit used in the Audi SQ7, with both cars sharing power, torque, and performance figures.
Visually, the Bentayga Diesel is distinguished from the W12 petrol model by a black mesh grille, quad exhaust tips, and standard 10-spoke 20-inch alloy wheels.
The diesel crossover is fitted with a 48V electrical system that not only powers the engine's electric compressor, but also the optional Dynamic Ride active roll control setup.
Standard equipment on the Bentayga Diesel includes multi-mode air suspension, hill descent control, predictive adaptive cruise control, and an infotainment system with an eight-inch touchscreen, satellite navigation, 60GB hard drive, and a 10.2-inch Android Entertainment Tablet for rear seat passengers.
On the list of options are electronic night vision, head-up display, responsive off-road settings, and a 1950W Naim audio system with 18 speakers.
Deliveries of the Bentayga diesel begin in early 2017 in Europe, with entry into the Australian, New Zealand, and other markets "planned across the rest of 2017".
