Plug-in Bentayga gets a stronger electric motor, a bigger drive battery and a sporty chassis tune, but is still missing a V6 engine worthy of the price

It must be tricky for car makers like Bentley to know how much and how quickly to commit to the electrification of its cars. A battle is being fought between the volume-selling premium brands at present, with new plug-in hybrid SUVs emerging month by month - from BMW, Land Rover, Mercedes-Benz and others - with upwards of 60, 70 or even 80 miles of official ‘equivalent all-electric range’.

To a certain extent, it’s a battle that Bentley can afford to stand and watch, as nobody buying the new Bentley Bentayga S Hybrid will be worrying about benefit-in-kind tax bills. But it can only stay on the sidelines for so long, because soon enough, the customer is going to start to wonder why that colleague’s Range Rover can do 70 miles between charges while their Bentayga struggles to manage 30.


That, for now, is where the Bentayga rests in this fast-changing market for electrified luxury transport. Crewe introduced the Bentayga Hybrid in 2019, as its first electrified car. But, having now been through the process with the Flying Spur, it has revisited its big SUV and found some ways to improve the offering. It has also lately added new comfort-orientated ‘Azure’ and sporty ’S’ derivatives to the Bentayga Hybrid model line, and it’s the latter we’re testing here. 

What it hasn’t done, regrettably, is swapped the 3.0-litre version of the Volkswagen Group’s EA839 V6 petrol engine for the shorter-stroke, higher-output, twin-turbocharged 2.9-litre one that has powered the Flying Spur Hybrid from the start, and that also serves in the likes of the Audi RS4 and Porsche Cayenne S. So, even though the badging of the new Bentayga S Hybrid might suggest otherwise, it doesn’t run the same powertrain as the equivalent limo.

It does have marginally more power and torque than it used to, by dint of improvements to its motor, and a slightly longer EV range. It has a special sports exhaust, and a sound generating resonator under the bonnet to make up for the combustion engine's slight lack of audible presence. It has sporty seats and bumpers, and lots of racey-looking carbonfibre body trim if you want it. But, to drive at least, it isn’t a car transformed in quite the way that you might have hoped for.

That’s no particular fault of the car’s new S-specific suspension settings, it must be noted. The S Hybrid gets the same uprated adaptive air suspension as the V8-engined S, with its damper rates increased by 15%. It doesn't get Bentley’s Dynamic Ride active anti-roll bars, because of the packaging of the PHEV system – although I wouldn’t say that you miss them.

This car has creditable body control, chassis response and handling precision for the big, luxury conveyance that it is (it’s nearly 250kg heavier than the S) and will maintain both its dynamic composure and ride isolation fairly well if you choose to hurry it along. So there’s more than a modicum of sporting appeal about the driving experience.

The slightly disinterested-feeling V6 is just a little unworthy of one of Bentley’s S badges, though. Even when the electric motor is doing all that it can to assist, it still feels a little bit short on accessible torque in a car of this size and weight, needing revs (and downshifts from the slightly lazy, slow-witted torque-converter automatic gearbox) before it produces anything close to really commanding pace.

When you’re cruising around in EV mode, Bentley’s improvements to the Bentayga's battery and electric motor do tell. You can comfortably spirit it up to the far side of 50mph in the sweep of daily traffic without needing any extra grunt from the engine, and if you keep to those sorts of speeds, you will find 30 miles of EV driving easy enough to achieve.

Just how long that will continue to be judged enough for a £185,000 PHEV SUV when alternatives that cost half as much will go twice as far and farther is now Bentley’s problem to contemplate. Funnily enough, for a Bentley customer, I would imagine that a better combustion engine might even be a higher priority.

I think your wrong, I don't think owners will care a jot about its EV range or eco credentials. It will go to someone with their own company of sorts they can put it on the books as a company car. The PHEV will be 10 to 15 grand less tax PA than the conventional 4L and on a car depreciating around £1.50 per mile it all adds up. EV range doesn't come into it, will never see a plug. Its all about tax.
