Bentley Motors has introduced its first diesel model: the Bentayga Diesel SUV. At its core is an all-new, technologically advanced, triple-charged, 4.0-liter, 32-valve V8 engine. Developing 435 PS (429 bhp) and 900 N·m (664 lb. ft.) of torque, the Bentayga Diesel hits a top speed of 270 km/h (168 mph) and can accelerate from 0-100 km/h in 4.8 seconds (0-60 mph in 4.6 seconds). Peak torque is available from very early in the rev range (just 1,000 rpm).
The Bentayga Diesel, equipped with a start-stop system, has the lowest CO2 emissions of any Bentley (210 g/km), as well as a range of more than 1,000 km (621 miles)—allowing owners to, for example, drive from London to Verbier, Bordeaux or the Scottish Highlands on a single tank.
The Bentayga Diesel represents a moment of immense significance in Bentley’s history, by giving the world its fastest luxury diesel SUV. Immense power, grand touring capabilities and superb refinement – this is a true Bentley.—Wolfgang Dürheimer, chairman and chief executive of Bentley Motors
The Bentayga Diesel retains the dynamic performance of the Bentayga W12, while introducing clean technologies and enhanced range.
The next-generation 4.0-liter V8 engine is mated to a ZF eight-speed automatic transmission. Variable-geometry, sequential twin-scroll turbochargers are powered by the exhaust gases, while a third electric supercharger—powered by Bentley’s innovative 48V system—spools up within 30 microseconds to eliminate turbo lag.
The effect is effortless, seamless power delivery across the entire engine-speed range.
The new model has also been made with a number of specific developments to provide peerless refinement. For example, the bespoke exhaust system has been acoustically engineered to be as quiet and refined as possible. The addition of Selective Catalytic Reduction contributes to lower NOx.
The Bentayga Diesel can be specified with Bentley Dynamic Ride—the world’s first electric active roll control technology that utilizes a 48V system. Inherent in larger vehicles with a higher center of gravity, this system instantly counteracts lateral rolling forces when cornering and ensures maximum tire contact to deliver class-leading cabin stability, ride comfort and exceptional handling.
Bentley’s adaptive and reactive system provides variable torsional resistance, allowing the Bentayga to be both dynamically capable and comfortable for all occupants at all times. The pioneering use of a 48V system—which on Bentayga Diesel utilizes a new lithium-ion battery system to offer even greater reserves of power—results in silent, instantaneous responses to deal with all road surfaces.
Electric Power-Assisted Steering (EPAS) is also featured on the Bentayga. The new system improves feedback to the driver, while providing isolation from steering kick-back both on- and off-road. EPAS also features a variable rack ratio, permitting light and fast steering while manoeuvring at low speeds, as well as a more subdued response for excellent stability at high speeds.
The Bentayga Diesel offers class-leading ride comfort, steering feel and handling thanks to the partnership of a highly sophisticated chassis and Electronic Stability Control (ESC). In addition to advanced, multi-mode Traction Control (TCS), the Bentayga also features Hill Descent Control.
Hill Descent Control automatically regulates the vehicle’s speed on steep declines, allowing the driver to concentrate fully on steering and obstacles ahead. It can be pre-set at speeds between two and 30 km/h (going in either direction) and works on gradients greater than 5%.
As with all Bentleys, the Bentayga Diesel comes with multi-mode air suspension. The driver has four different modes to choose from: High 2, High 1, Normal and Low. High 2, for example, can be manually selected when tackling more severe off-road surfaces. Customers can also lower the rear suspension via a switch in the boot, to ease loading and trailer hitching.
The Bentayga Diesel offers the widest range of on- and off-road drive settings of any vehicle via Bentley’s Drive Dynamics Mode and optional Responsive Off-Road Settings. Up to eight modes are available, allowing drivers, at the simple turn of a dial, to select the perfect dynamic set-up for any surface or road condition. This versatility is complemented by Bentley Dynamic Ride (electrically activated 48V active roll control) and Electric Power-Assisted Steering (EPAS).
Responsive Off-Road Settings allows the customer to select the appropriate vehicle settings for a wide range of off-road surfaces, while the Driver Information Panel displays information on pitch, roll, wheel articulation, steering angle, compass bearing and altitude.
Adaptive Cruise Control (ACC) including Stop & Go, Predictive ACC and Traffic Assist enables the driver to maintain a set distance to the vehicle in front. Predictive ACC uses the navigation data, sensors and cameras to predict upcoming corners, city boundaries and speed-limit changes and can then modify the vehicle speed accordingly, improving both comfort and fuel economy.
In urban environments, there are a number of driver aids available on the Bentayga Diesel. These systems—such as Traffic Sign Recognition, which detects a wide variety of traffic signs and displays information to the driver; Rear Crossing Traffic Warning, which uses radar technology to detect crossing traffic when reversing out of a parking space; and Top View, a system which uses four cameras to display an overall picture of the vehicle’s surroundings—combine to enhance everyday usability.
Park Assist is also available—a system that detects suitable parking spaces (both parallel and perpendicular) before autonomous steering takes over to support parking maneuvers, even in narrow and tricky spaces.
Other innovative systems available include Electronic Night Vision, which uses infra-red technology to identify potential obstacles ahead, and a Head-Up Display, which reduces driver distraction and increases safety.
Customer deliveries will begin in Europe early next year, with entry into Russia, South Africa, Australia, New Zealand and Taiwan planned across the rest of 2017.
