At the heart of the Bentley Bentayga is the all-new Crewe-built W12 TSI engine. This 6.0-litre twin-turbo unit combines efficiency and refinement with the luxury of unrivaled power and torque.
 
It is the most technologically advanced 12-cylinder engine in the world and develops 600 horsepower (608 PS / 447 kW) @ 6,000 rpm and 900 Nm (663 lb ft) from 1,250 rpm to 4,500 rpm. These mighty outputs result in equally impressive performance figures. The Bentayga is capable of dispatching the sprint to 60 mph in just 4.0 seconds (0-100 km/h in 4.1 seconds) on its way to a top speed of 187 mph (301 km/h).
The new W12 uses both direct and indirect fuel injection. Switching seamlessly between the two technologies, the combination of these systems maximises refinement, delivers low particulate emissions and maximises power and torque delivery.
 
An impressive efficiency figure of 292 g/km CO2 is made possible in part thanks to Bentley’s Variable Displacement system, which shuts down half of the engine under defined conditions. Intake and exhaust valves, fuel injection and ignition are all shut down on defined cylinders, with the engine running as a six-cylinder for improved efficiency.
 
The engine is mated to an eight-speed automatic gearbox. The transmission and four-wheel-drive system has been strengthened to handle the demands and high torque levels of off-road driving.
In Bentley’s advanced application of Start-Stop technology for the Bentayga, coasting is also available, as the engine rests not only when the vehicle is stationary but also at ‘near to stop’ speeds.
 
In 5th to 8th gear, when the driver releases the throttle (at motorway cruising speed, for example) the car will open the torque converter, dropping the engine to idle and simply allowing the car to roll or ‘sail’. When the throttle is reapplied, or the car starts going downhill and detects an increase in speed, the transmission is re-engaged.
 
The new W12 sees a 11.9% efficiency improvement compared to the existing powertrain. The Bentayga will also be available as diesel and hybrid variants in the future.
