*It's a big car with a big range - 28 August*
I haven’t yet found a single way in which our car’s PHEV powertrain is inferior to the petrol ones on offer. Practically speaking, it’s as quick, as quiet when wafting and emits as good a note when hurrying, but it’s massively more economical. The average fuel mileage for my charging regime (roughly once every 200 miles) is between 36 and 38. Range is thus well over 500 miles.

*Plug-in hybrid power is treating us finely in terms of both enjoyment and cost - 23 August*
One of the first things they tell you about habitual Bentley owners is how much they use their cars for lifestyle, business and high-mileage driving. These are working machines, Crewe people insist – and yet when a £250,000 Bentley comes your way to use as you like for three months, especially when it’s the biggest they make, a Flying Spur saloon, you find these comments a bit hard to believe.
At first you drive with trepidation, as impressed behind the wheel by this car’s presence as those who see its elegant Silver Frost flanks from outside. With its long wheelbase and highly adjustable four-mode air suspension, it’s so remarkably free from pitch that for a while you imagine it’s even bigger than it is.
This phase can run several days and 100 miles, but it doesn’t last. You wake up one morning with a big journey to do, slide into the duotone cabin of Porpoise and Cumbrian Green leather (gripped by the part-Dinamica seats) and the car seems to shrink around you. Suddenly 5.3 metres seems a normal length for a car, and the impression stays. From there, the mileage accumulates.
Since I first wrote about this car, in late June, I’ve done 3000 miles – and that without much city driving, because I’m a bit reluctant to expose the Bentley to kerbside damage and because my motley collection of two-wheelers is understandably better at inner-city progress and parking. Anyway, I don’t feel bad about using other vehicles; there’s some statistic that says Bentley owners have eight or nine other cars. It’s expected.
Two things assist you in the accumulation of miles. First, there’s no choice to make when a long journey is in prospect. No other car on our fleet is remotely as good at protecting you from fatigue as the Spur. You have the choice of actively enjoying the car’s progress – a mile-absorber of its own – or letting the lack of intrusion settle your mind on other things. Whatever, you’re assisted by the car’s long range. With 31-33 miles of electric-only running on a full battery and a brimmed petrol tank, you’re offered around 575 miles before refuelling – far more than you will need at one sitting. Or three sittings, probably.
Covering, say, 500 of those miles without recharging will cost you just over £100. You will pay around £6 in home-charging power plus £95-£97 for (preferred but not compulsory) super-unleaded.
Now that I’ve amassed 3000 miles, it’s possible to say with certainty that the trip computer appears to be optimistic by around 0.6mpg (provided our nation’s fuel dispensers have been accurate) and that the Bentley’s true fuel mileage over that distance has been a deeply impressive 36.7mpg.
Chuck in around £75 for electricity, according to the app that monitors my Andersen charger at home, and you have the Bentley’s fuel costs laid bare.
In my view, this car makes an extremely powerful case for the plug-in hybrid as a propulsion medium for the large, heavy car. This is a 2.5-tonne saloon, remember, with a 0-60mph time of just 4.1sec and a 177mph top speed. Admittedly, you don’t use such potential often, but its ready presence is always detectable via the accelerator. It’s also obvious whenever you glance at the tacho at 70mph, barely showing 1500rpm. Sometimes, of course, it’s showing nothing at all, because the Bentley shuts down its twin-turbocharged 3.0-litre V6 engine completely.
There are niggles. The car can tend to roll forward a few feet when you’ve just selected reverse – an undesirable phenomenon – and, as with other Bentleys, I would appreciate a more alert accelerator in my first second or two off the mark. But in the main, this PHEV powertrain doesn’t require Bentley regulars to accept any significant compromise, and in some phases of motoring, it’s the quietest and smoothest of them all.
In short, Bentley’s PHEV progress goes in the direction of driver enjoyment as well as in helping save the planet.
*Love it*
*Walking on air*
Its grand, pitch-free ride puts it in a totally different class from normal cars, and not many price rivals are true comfort competitors either.
*Loathe it*
*Tiny capacity*
Boot is at odds with car’s huge size and spacious cabin. Battery has to go somewhere, but some owners will need a luggage van following.

*More praise for our PHEV's frugality **- 9 August*
The Flying Spur PHEV is amassing miles rapidly and the fuel mileage has become amazingly consistent. You get 44mpg on a 100-mile trip, starting with a full battery. That falls to 39mpg if it’s a return (ie 200-mile) journey. And you get 29.9mpg – yes, that precise – when you start a journey with the battery depleted. The overall consumption is now stable at 36.2mpg, a superb feat.

*Hybrid power is proving to be the all-important choice - 26 July*
Before this car arrived, I only half-believed it would effortlessly acquire miles the way people said it would. It’s so long, and so expensive. But my consciousness of the size has melted away and (however daft it sounds) I feel freed of the scary cost of fuel by a 36mpg average fuel consumption, over 2000 miles. That’s what a hybrid can do for you.* *

*Welcoming the Flying Spur to the fleet - 19 July 2023*
It’s always a great moment when a Bentley arrives in the Autocar household. It alters behaviour. People start positioning themselves to drive it and the list of aspirants grows. It swells further if potential drivers hear that this Bentley is a V6-powered plug-in hybrid, equal in performance to a V8 but much more economical if you religiously charge its 18kWh battery when opportunities present.
The queue has been shorter this time, because the plug-in hybrid in question is a Flying Spur limousine, whose 5.3m length means it won’t easily fit our small office car park. And our usual multi-storey across the road (admittedly built for the Morris Minor) is entirely out of the question.
Which is not to say the length should be viewed as a shortcoming. This Bentley is a full-on limousine, a relatively practical car that excels at special occasions, as you learn the first time you open one of the long rear doors and survey the plush rear cabin. I have discovered that among the earliest instincts of a Spur debutant is to find excuses to take friends for rides.
I took delivery of the Autocar Spur at Bentley High Wycombe, a new dealership just off the M40, north-west of London. I’d discovered the place a few weeks before on the rebound from a nearby JLR dealership (I’d been surveying used car stock, a warped kind of hobby) and had been roundly ignored. I spotted the Bentley sign by chance, wondered if they would be more welcoming, and of course they were.
A friendly and non-pushy sales exec called Andrew Bradburn proved to be helpful and knowledgeable, so when we were later discussing with Bentley HQ a suitable place for the new Flying Spur Hybrid to be delivered, I thought of High Wycombe and everyone was happy with that. I arrived on the appointed day, met various staff members led by dealer principal Ian Smith, and spent an hour learning about our new car (again with Andrew Bradburn leading) before driving it away, dosed with quality coffee and very well briefed.
The Hybrid’s major claim is its petrol-electric powertrain. It is pretty similar in overall weight to a V8, except that its battery weight migrates to the lower boot, which gives the weight distribution a 52% rearward bias. In practice, you feel nothing different. What you do notice, though, is the lack of the four-wheel steering system (omitted to make space for the battery) that has been available with non-hybrid Spurs since 2020. The Hybrid isn’t cumbersome, but you’re always aware of its size where the 4WS versions feel almost compact.
However, there are no other drawbacks and some big advantages. So far, my overall fuel consumption is 35.5mpg, a cool 10-12mpg (or around 50%) better than I’d get from a V8. Of course, the available EV-only mode comes with amazing refinement, but you hardly notice when the twin-turbocharged V6 chimes in, both because that’s also refined and because the integration of the different drive sources is first class. And it goes. The figures say it’s a shade slower than the V8 and W12, but a Spur Hybrid can still lay down an effortless 0-100mph sprint in 10.2sec, which is all you need to know.
The battery-only range – quoted at 25.5 miles – has so far turned out to be 33 miles, which doesn’t match a Range Rover’s prodigious 50-odd miles but is still handy. It is delivered by a strong 134bhp electric motor that sits between the 2.9-litre V6 engine and the eight-speed automatic gearbox (and, like all electric motors, it delivers maximum torque at step-off), and the EV-only performance feels accessible and powerful.
The car will frequently cruise on motorways at 70mph with the engine off. At my Gloucestershire domestic power rates, using a 7kWh Andersen charger, a full charge (the battery’s usable capacity is 15.1kWh) takes a little less than two and a half hours and costs a shade under £6. When I acquire more experience, I’ll do the sums properly.
For the first few days, I treated the Flying Spur with an excess of reverence. I couldn’t help it: even if you’ve driven your share of expensive cars, it’s hard to act normally in a £250,000 Flying Spur. I mean, what is normal? I kept doing two conflicting things: trying to emulate the casual aplomb of people who actually buy cars like this, and imagining the awfulness of contacting a granite kerb with one of the 22in sports alloys finished in Pale Brodgar Satin, a £4770 option.
In succeeding days, I have become more used to the car, not least because its excellent steering allows it to be placed very accurately on the road, and its long wheelbase (as well as delivering a brilliant primary ride) gives it excellent directional stability. I’m not entirely sold on the secondary ride, mind. Those 22in alloys occasionally introduce the jitters. Still, we’re getting on well, the Spur and I, and I predict an even closer relationship in future.
*Second Opinion*
I think the Hybrid might be the best Flying Spur. It’s refined; it’s fast; it’s slick and polished in operation; it’s got just that bit more driver appeal than you expect of a car its size; and, with the electric running, there’s a duality to it that no other Spur has. This is how to electrify a luxury car: considerately.
