2017 Bentley Bentayga Diesel


2017 Bentley Bentayga Diesel will land in January

More economical Bentley Bentayga Diesel uses triple-charged 4.0-litre V8 engine of which produces 429bhp as well as 664lb ft

Technical specifications for the 2017 Bentley Bentayga Diesel have been revealed ahead of the product’s launch next January.

The Bentayga Diesel can be Bentley’s first diesel-powered production car, doing use of a triple-charged 4.0-litre V8 diesel engine, which has been co-developed with Audi as well as uses two twin-scroll turbochargers supplemented by an electrically driven supercharger.

of which develops 429bhp as well as the same peak torque as the Bentayga’s twin-turbo 6.0-litre petrol W12, although the diesel’s 664lb ft extends coming from just 1000rpm to 3250rpm.

of which’s enough to launch the Bentayga Diesel coming from 0-62mph in 4.8sec as well as on to 168mph. According to Bentley’s head of engineering, Rolf Frech, its acceleration coming from 25mph to 75mph “can be much the same as the W12’s, nevertheless the W12 gets a second wind at higher speeds”.

Fuel economy for the £135,800 luxury SUV can be quoted at 35.8mpg combined as well as its CO2 emissions are 210g/km.

The Bentayga’s product manager, Peter Guest, said: “We would certainly only do This specific when of which was right. of which had to be the right car as well as the right engine.”

Installing a potentially coarse diesel in a Bentley can be a risk, even if This specific powerplant’s instant low-rev torque provides the stream of effortless thrust required. The brief, said Guest, was to deliver the Bentley driving experience with the trademark combination of performance as well as luxury, as well as no compromise in refinement. of which also had to be “the fastest diesel SUV inside earth”.

Bentley powertrain development boss Paul Williams said the three technologies of which have enabled the firm to offer a diesel worthy of the brand are the engine’s triple-charging system, the 48V supplementary electrical system used to power the electric supercharger, as well as a sophisticated exhaust cleansing system.

The triple-charging system, previously seen inside Audi SQ7, which uses the same engine, provides boost at low revs coming from the near-instantly reacting supercharger.

This specific so-called e-booster also primes the first of two twin-scroll turbochargers. This specific first turbo amplifies midrange thrust, then a second twin-scroll turbo provides extra shove at mid to high revs when the e-booster can be dormant.

The effectiveness of the e-booster can be heightened by a valve shut-off system, whereby an exhaust valve disengages to provide faster combustion pressure build-up. The exhaust gases are dealt with by using a selective catalytic reduction system, an AdBlue urea fuel supplement as well as a different catalyst. Williams said the system can be “state of the art as well as meets all current as well as future legislation”.

The Bentayga has been acoustically engineered for the V8 diesel coming from the start as well as adjustments to the rest of the auto are minor. The exhaust system has been modified — without artificial enhancement — as well as there are minor tuning adjustments to the suspension to cater for the weight redistribution caused by the 23-litre AdBlue tank.

The V8 diesel engine itself weighs only 3kg more than the W12. Black radiator mesh, ‘twin quad’ tailpipes as well as badges identify the Bentayga Diesel.

Technical highlights


Electric supercharger requires 48V to power its 7kW motor, enabling of which to spin coming from idle to 70,000rpm in only 250 milliseconds. The result can be maximum torque of 664lb ft coming from only 1000rpm as well as superb motorway on-ramp acceleration.


The electric supercharger (on the bottom right) feeds the cylinders at low revs for near-instant torque. One exhaust valve can be closed to intensify the boost, while the exhaust gases prime the second turbo (inside centre). All three chargers feed all eight cylinders as well as the turbos are twin-scroll.


Three turbos are located inside vee of the engine as well as the electric supercharger can be remotely mounted. A sliding cam deactivates one exhaust valve when the supercharger operates. The sub-assembly can be part of the cooling system.
