From £58,6009
Dual motors and a power hike give Tesla's electric family car supercar acceleration - and the rest of the package is as strong as ever

Our Verdict

Tesla Model S 95D

In theory, this all-electric luxury car looks a hit. So is it in practice?

27 February 2015
2015 Tesla Model S P85D

What is it?

The Tesla Model S has already wowed us in conventional form - if, indeed, the rear-wheel-drive, fully electric family hatchback could ever be called ordinary. Described in its full Autocar road test as "practical, refined and desirable - a triumph", the Model S has been available so far in a couple of guises: the regular 85, with 376bhp and a range of 310 miles, and the more modest 60, which has a smaller battery and a reduced range of 240 miles.

The P85D is something else altogether. Instead of a single electric motor driving the rear wheels, it gets one on each axle to run in four-wheel drive - and the upgrades don't stop there. The rear-mounted motor gets Tesla's Performance designation (the 'P' in the model name), raising it to 464bhp, and with the front wheels offering an additional 218bhp, you suddenly end up with an entirely respectable-looking five or seven-seat family hatchback, with a combined output of 682bhp and 687lb ft.

The resulting performance figures are pretty staggering. The top speed is a run-of-the-mill 155mph, but 0-60mph is claimed to take just 3.2sec. Let's think about that for a moment: that's the same time, to the tenth, as the official Autocar benchmark for the Ferrari 458 Speciale (the regular Italia is 0.1sec slower). It has the potential to make the P85D's list price of £79,080 look a bit of a bargain - especially when you consider that free access to Supercharging - Tesla's ever-expanding network of quick charging points - is included as standard.

Nor should P85D users be any more susceptible to range anxiety than owners of more conventional Model S editions. Tesla claims that the car's digital power controls can utilise two motors more effectively than one - so there's actually a modest gain in range over the old rear-drive P85. It's now 300 miles, just 10 miles shy of the regular 85.

Incidentally, the new model sits on top of a revised range, where the twin-motor four-wheel drive set-up (identified by the 'D' suffix) is also available as a £4100 upgrade to the regular 85. That edition gets a regular 50/50 power split between front and rear axles, though, with the same combined output as the 85. In the meantime, Tesla has quietly dropped the rear-drive P85 from the line-up; its reasoning is that anyone who wants the extra grunt will be happy to pay for the four-wheel-drive model that can make better use of it.

What's it like?

To activate the P85D's full potential, you press a button on the huge central touchscreen marked (and I'm serious about this) 'Insane'. And that's pretty much how it feels. Tesla's acceleration test track was a well-abused mixture of greasy cold asphalt and coarse gravel, but the P85D still managed to deliver a level of acceleration that would be difficult for anything else to match in the same conditions. It's the initial punch that does it - the kind of uncompromising shove from 0-30mph that comes with the torque characteristics of electric motors in general, now mixed with four-wheel drive.

What's missing, of course, is any sort of soundtrack. There's none of the sense of occasion that you get with a 458 attempting similar feats - or anything approaching the aural pleasure that can be delivered by a hard-worked AMG V8. Instead, you hear a distant whoosh as the twin motors kick in, accompanied by - and this is perhaps oddest of all - the sounds of the tyres themselves grabbing hold of the surface beneath them (on a dry road, presumably, you'll not even hear that).

Once you're up and running, there's even less standing in the way of the P85D's colossal torque; you'll need to be well beyond the UK speed limit before you'd detect any discernible reduction in the car's ability to gain momentum.

Try to carry too much speed into a corner and the P85D will simply understeer; behave yourself and the nose tucks in with more conviction than it does on the 85 (itself not a bad steer, by any measure). Regardless of how hard you're pushing, it stays admirably flat in corners - and there was enough compliance to dial out the worst road surface imperfections on Tesla's Norwegian test route. 

There's still not much communication, though; you get three weights of steering to play with, but despite this, and regardless of the P85D's ability to thrill and delight every time the traffic lights go green, this is not a car that makes you feel truly connected to what the tyres are doing. In that respect, at least, the P85D feels like one of the family - a slightly more planted and considerably quicker stablemate to the 85 and 60.

The same can be said for refinement, really, because the large alloy wheels still create a fair amount of road roar once you're above 40mph. It's by no means noisy aboard the P85D, but nor is it as silent as you may expect a fully electric vehicle to be.

The cabin remains a clever bit of packaging, with room for five adults and potentially two further children in rear-facing seats in the boot. The luggage capacity is still enormous, with space under the bonnet and in the traditional boot totalling almost 1800 litres. The finish on materials is of a remarkably high standard compared with any other American car - although a few elements are half a notch behind the best European executive models when you get to a close-up inspection.

The showpiece of the cabin is still the Model S's gargantuan centre screen, a 17in behemoth of a touchscreen through which you control the majority of the vehicle functions, let alone infotainment or navigation. It's still a bit worrying to see the system redrawing chunks of map as it struggles to keep up with sheer amount of real estate it has at its disposal, and there are occasions when you'll wish they'd just fitted a permanent button - Volvo's new system on the XC90 does a better job of fast-tracking you to regularly used functions - but in the most part it's a triumph.

Tesla has also rolled out the music streaming service Rdio to its cars via an over-the-air upgrade. In theory, the system allows you to press a steering wheel-mounted button and request any song - and voice recognition and a data connection will do the rest. In practice, you may find the search facility and data speeds more limiting than your own imagination.

Should I buy one?

If you're in the market for a Model S - and we can think of plenty of reasons why you could be - then it's going to be hard to resist the all-round performance increase and all-weather ability of the P85D. It does feel noticeably quicker and a little more secure than a conventional 85, and the four-wheel drive means that it stands a chance of keeping you moving on those three days a year where the weather grinds Britain to a halt.

You're paying a fair old premium, though; the four-wheel-drive 85D is still a car that can crack 0-60mph in just over five seconds, and there's a £14,000 hike from that car to the Ferrari-rivalling pace of the P85D. Even if you finance (the most appealing way into a Model S, realistically), you're looking at a premium of around £300 per month for a couple of seconds off the 0-60mph time.

Many will look at the raw figures, do the maths and, with a tinge of regret, allow head to overrule heart. Those who don't will be picking one of the most remarkable production cars on sale today.

I'm struggling to find many reasons why anyone would buy a Porsche Panamera over a Telsa. Still each to own.

When the Porsche is low on fuel you can go to any filling station in the western world and fill up in a few minutes, beyond that, not much.

There are a few videos of the 'insane' mode being used on unsuspecting passengers, makes for a good few minutes entertainment.

Friend here has one (I am sure he will exchange it for this) and
has written a warning note on the passenger side
because when he slams the GO peddle (it isnt the loud one any more)
you can seriously damage your neck - it has that much poke !!
These changes - WONDERFUL and make it even more worthwhile. Just need to find the lolly

Bless the Americans for not knowing that in Europe (or the the rest of the world I'd wager) D stands for Diesel. This should have been the P85T - for Twin Engine. Which also to most Europeans conjure up images of T for Turbo.

But what a car for a measly £80,000. Now if they can just get rid of that shapeless awful grille on the nose (on a car that doesn't need a grille at all) all will be well.

Useless for me, though they look good and the performance is impressive.I live in the Arctic 1500 Km north of a major city,in Travel you even have to carefully calculate fuel range.A colleague's Prius died in the cold so at -40C I don't think the Tesla would do well.What also about the "greenness" of the power from the Grid,a diesel powered station as our Hydroelectric system is down,or in UK some coal fired power, as the Nuclear ones have been shut down,Yeah,really green that choice!

The combination of pace, refinement and (claimed) range offered by this car looks nigh on irresistible. But could you live with it? I suspect that in the real world, the actual range, time taken for recharging and the lack of recharging points would cause real issues - and how much would a two or three year old Tesla be worth on the used car market?
I'd like to see Autocar run one for a year or two and report on the experience.

27 February 2015
That's one staggeringly quick sprint and makes Tesla the Usain Bolt of executive saloons - quite a few long strides ahead of the competition that is if there is any.

P85D sounds like a form you fill in for HMRC.

I do love this car though. I would certainly contemplate one if I could afford it. An Audi RS6 is possibly the closest rival, similar price, similar performance.

It all sounds well and good, but the stated range is just like the mpg figures that manufacturers give. It represents the absolute maximum that can be eked out by specialist testers in ideal conditions. And every rechargeable gadget on sale proves that battery life will deteriorate far faster than mpg will diminish. I'm sure the acceleration is massive fun if one does all one's driving within ten minutes of home, but it would be essential to have another car sitting on the driveway for long journeys. And while yes, most people shelling out such money could afford a second car, it's on the long distance drives that a big, powerful car is really appreciated, so owners would probably feel the urge to find about the same again for an M5 or similar. As madmac has pointed out in a previous post, electric cars aren't as green as they're made out to be, they just shift the emissions to the power stations, but if most owners need to have a conventional car in addition to cover for the electric car's shortcomings, that applies even more.
