McLaren 720S vs Jaguar XJ

What's the difference?

Past McLarens have been accused of being a bit soulless, but this one is alive. The last time I felt like this in a car was a Ferrari F12, one of the scariest but most brilliant cars I've ever driven. Except the 720S isn't scary on the road, just sheer genius.

The 720S doesn't necessarily beat the competition but it opens up new ways of doing supercar things. It's a car that looks amazing, is more than fit for purpose but has a wider range of talents than the others. 

That makes it ever more compelling, both as a piece of automotive brilliance to admire, andl as something to consider when you've got half a Sydney apartment to spend on a car.

Australian roads await, but the drive through rural English country roads and villages was a great preview. All I can say is: gimme one.

It might be old and facing German competition bursting with advanced technology, but the XJR is still a car you can buy with heart and head. But mostly your heart. It goes like stink, has a much better interior than the Quattroporte and is more interesting than just about anything this big or this grand.

It's also a better car than the Maserati Quattroporte if you want to get on with the driving yourself and is far prettier than the Porsche Panamera. It's a wonderful thing and even more wonderful that Jaguar continues to build it. Long live that supercharged V8 and the XJ is a great home for it.

The 720S has received mixed reviews but nobody will say it isn't striking. I love it - every designer says their influence is a Lockheed SR-71 Blackbird (designer Melville even jokes about it), but you really can see it in the 720S, especially in the cockpit design, which looks like a glass canopy from that surveillance jet.

McLaren's signature dihedral doors, which go all the way back to the 1994 McLaren F1, are substantial, with a double skin to act as a serious piece of aero kit.

Melville told me in January that he thinks the cars look shaped by nature, using the example of a stone left in a stream to erode. The 720S is full of details evoking that image, with a clean, taut surface. Where everyone complained that the 12C was "designed in a wind tunnel", the 720S looks designed by the wind. In the carbon and aluminium, it looks extraordinary.

One of the most talked about features are those headlights - almost always finished in black, they're known as "the socket". When you get close you see slim LED DRLs, small but powerful headlights, and you then discover two radiators behind them. Follow it through and the air exits through the bumper, around the wheels and then through the door. It's quite something.

Inside is the McLaren we've come to know and love, but with a clever kicker. The dash panel looks lifted from a race car - but with far nicer graphics. Switch to "active" mode, turn everything up to Track and the panel swings down and presents you with a minimised set of instruments to reduce distraction and make up for a lack of head-up display - just speed, get and, revs.

The XJ has a marvellously exaggerated length, with a rear overhang redolent of Jag's sporting coupe and roadster pair of the time of its launch, the XK. There's nothing else in the segment like it, with the three Germans - Mercedes' S-Class, Audi's A8 and BMW's 7 Series - having gone all Hugo Boss and and in the latter two's case, almost shrinking violet. The only credible Japanese alternative, the Lexus LS, looks like a Lexused 7 Series. The XJR is a more emotional car, like Maserati's Quattroporte.

The R adds an aggro grille, 20-inch wheels with low-ish profile tyres, a bootlid spoiler, red brake calipers and vents in the bonnet. Bits and pieces get the black gloss treatment and there are V8 and R badges, as well as a rather large leaper on the bootlid. Capping it all off are four exhausts poking out from the bumper and distinctive vertical taillights.

Inside remains largely unchanged. The cabin is big and luxurious, leather-lined and very, very comfortable. The front air vents have to be modelled on the de Havilland Comet's integrated jet engine intakes and, again, the dash design stays away from the horizontal lines of its obvious competition.

There is probably a bit much chrome for my liking, particularly on the centre console and around the rotary dial shifter, which reflects sunlight into your face during the day.

The lovely 'Riva Hoop' - a band that sweeps from door to door across the top of the dash - is a great touch and remains a defining feature in the cabin. The last update brought an Audi-like digital dashboard, including maps, but it's not nearly as slick as the German. The graphics for the dials are good (and quick) but the maps are a bit so-so.

For a supercar, there is a surprising amount of space in the cabin. You can strap 220 litres of (hopefully) soft stuff on the rear shelf behind the seats and there's a 150-litre boot under the nose. You can store your track gear under there, including helmet, or even cram in a few soft bags for a weekend away.

Again, unusually a for a supercar, you're also  treated to a couple of storage cubbies in the centre console.

There's plenty of room in cabin for two bodies and the driver's seat offers lots of adjustment. Despite being so close to the front wheels, your feet have space even for my ridiculous duck feet to fit easily. There's even enough headroom for those over six feet, although the glass portholes in the top of dihedral doors might not be so welcome in an Australian summer.

It might be over five metres long, but the Jag's cabin isn't as gigantic as that might suggest - luckily, if you want space, the XJ L has it. The SWB version is roomy enough, though, just not palatial. You can fit five people, but the big transmission tunnel will limit the size of that fifth.

Front and rear passengers have a pair of cupholders each, with rubber bubbles to help hold smaller cups in tight. The front and rear doors have pockets but aren't really for bottles.

Boot space is a reasonable 520 litres, with a space saver spare under the floor.

As is expected at this level, Jaguar was not mucking about with price or specification - the XJR starts at a mildly terrifying $299,995, which is very close to the rather more tranquil Autobiography long-wheelbase relax-o-mobile.

Standard are 20-inch alloys, a 20-speaker stereo, power everything with three memory positions, four-zone climate control, keyless entry and start, front and rear parking sensors, heated and cooled front and rear seats, sat nav, LED headlights and DRLs, leather everywhere, auto wipers and (LED) headlights, electric boot lid, heated steering wheel and a space saver spare.

The Meridian-branded stereo is an absolute cracker, powered by the improved but still laggy 'InControl Pro' system. Oddly, it's all crammed into an 8.0-inch touchscreen when there is seemingly room for the larger (and better-performing) 10.0-inch screen. The software is far superior than the version that preceded the last update, but the screen is hard to use, as targets are placed right in the corners and are hard to hit.

Apple CarPlay and Android Auto are also absent, and the sat nav is still fairly dopey.

A long list of options are available, some of which should probably be included in the big sticker price - DAB+ ($620), premium paint is a splutter-worthy $2060 (although, to be fair, the vast majority of the 19 colours are free), adaptive cruise with queue assist ($2200), adaptive headlights a further $2620 and 'Parking Assist', which adds side sensors and a front camera, a further $2780. Reverse cross traffic alert, blind spot monitoring and forward collision warning cost yet another $1460. Ouch.

The 720S runs a 4.0-litre version of McLaren's familiar flat-plane crank twin-turbo V8. Power is up to 537kW (or 720PS, hence the name) and torque up almost 100Nm to 770Nm, from 678. McLaren says 41 percent of the components are new.

A seven-speed twin clutch sends power to the rear wheels and the 1283kg dry (down 106kg from the 650S) monster hits 100km/h in 2.9 seconds, surely a cautious claim. The more alarming 0-200km/h clam is a terrifying 7.8 seconds, half a second quicker than its closest rival, the 488 GTB. That is seriously, insanely quick, while top speed is equally bonkers at 341km/h.

Instead of a complicated and heavy active differential, the 720S uses the rear brakes and various other methods to get the same effect. It's one of several ideas pinched from F1, some of them now banned.

Jaguar's lovely 5.0-litre V8 with supercharger continues under the XJ's long and shapely bonnet, delivering a walloping 404kW and a tyre-shredding 680Nm. The sprint to 100km/h for all 1875kg of XJR is completed in an impressive 4.6 seconds, which was very competitive at the car's launch in 2009.

Power reaches the rear wheels via ZF's eight-speed automatic and you can control it with the tacky plastic paddles on the steering wheel. Oh, and it has stop-start.

McLaren claims the European combined cycle could return 10.7L/100km, but we have no way of knowing if that is accurate because we weren't mucking about on the day we had the car.

The combined cycle figure for the V8 is listed at 11.1L/100km but fully expect to see the 16.1L/100km we got, especially as you try and fail to tyre of the monstrous power delivery and lovely (if muted) V8 roar.

Luckily, even if you're belting it, the 82 litre tank is a generous size and you'll cover a fair amount of ground.

One of the biggest changes from 650 to 720 is the new Monocage II carbon fibre tub. The drop in overall weight is partly because the cage now includes the windscreen hoop, which previously was metal. Kerb weight with all fluids and a 90 percent full fuel tank (don't ask why 90 percent, I don't know either) it weighs 1419kg, giving it the same power-to-weight ratio as a Bugatti Veyron. Yikes.

The 720S is an astonishing car. We always say you can pootle in a modern supercar, but the 720S is so user-friendly, maneouvreable and so easy to see out of - there are no significant blind spots with an almost entirely glass roof - you can tackle city and country in comfort mode and actually be comfortable. Comparatively, a Huracan goes all blergh in Strada mode and the 488 GTB never stops begging you to kick it in the guts. The McLaren is easy, liveable and smooth. 

I was driving a left-hand drive car in the UK, which should have been a complete nightmare, but it was fine - the vision is excellent, particularly over the shoulder. 

But when you do decide to kick the 720S into action, it's wild. The acceleration is brutal, the handling impeccable and the ride, oh, the ride. No supercar can handle bumps, irregularities and flat out poor surfaces like the McLaren. The 540C's ride is incredible as it is, but the 720 is just wow.

Because it's quite light, the nose goes where you point it, the huge brakes have less to stop, the towering power less to push. The steering in the 720S is well-weighted but has tons of feel - you know what's going on underneath the double-wishbone sprung front wheels and you can adjust what you're up to accordingly. The stability system is excellent, too. Never overbearing or abrupt, where talent ends and the help begins is delightfully blurry.

The new engine is a bit more tuneful than past McLarens - there's even a loud-start party trick - but it's not loud and overbearing. You'll hear turbos whisting, sighing and pshawing, a deep bassy exhaust note and some awesome intake roar. But there's not much off-throttle character. It does at least do away with the histrionics of the Italians.

The only serious drama is the amount of noise bouncing around the cabin over about 100km/h. There's a lot more glass than sound-soaking Alcantara, which explains some of the extra tyre racket over a 650S. You can't have everything, I guess.

Indecently quick, surprisingly agile and heaps of fun. While the first descriptor applies purely because of its size, the next two shouldn't when you're in command of 5.13 metres of motor vehicle. As with the Audi and now the 7, the Jag has a lot of aluminium to help keep the kilos off and good gracious, it has worked.

The R is based around the short wheelbase version of the XJ for perhaps obvious reasons. Even so, it appears to be the shorter-again XF's because this thing turns in like a demon. No, it won't stay with the dearly-departed XF-R but it does a mighty fine impression of one, just with a better ride quality.

Rear seat passengers should be prepared to feel a lot of wheelslip, especially when in Dynamic mode, as even the fat Pirelli P-Zero's struggle for purchase when the right foot hits the carpet. The V8 rumbles rather than bellows, but the rears cheerfully spin up until the computers and active differential rein things in. Traction control off and you've got a proper tyre-smoker if you're not playing by the rules. Jag's engineers are clearly hooligans at heart.

As always, ZF's eight-speed transmission does an incredible job of marshalling the horses in a rearward direction and when you're not after a bit of sound and light, have achieved a tremendous amount with the damping. When in normal mode, the car glides along, so much so that the lady of the house wasn't so sure it was a sporting sedan.

Once she was apprised of dynamic mode (you have to cycle the button through winter mode first, for some reason), her only complaint was that it was too long and the steering wheel too big for this type of car. I was persuaded of the latter, especially after stepping out of an Audi S3 which has a tiny wheel. Long story short, the XJR is now 'her' car (to be more accurate, the XFR is, but that hasn't arrived yet, so...), as it felt smaller than it was when not parking and she's a sucker for a torquey V8.

The whole XJ range has six airbags, ABS, stability and traction controls, emergency brake assist, reversing camera, three top tethers and two ISOFIX points. The XJ doesn't have an ANCAP safety rating.

The 720S comes with McLaren's three-year/unlimited kilometre warranty with roadside assist. McLaren will want to see you every 12 months or 20,000km, which is quite unusual at this level.

Jaguar offers a three year/unlimited kilometre warranty and roadside assist for the same period.

Like the F-Type, XJ owners benefit from three years/100,000km free servicing.
