Infiniti Q60 vs McLaren 720S

What's the difference?

Beautiful looks, good handling, but the driving experience of the Q60 GT is let down by a numbness and disconnection relative to what's happening under you. Refinement isn't on the same level as its BMW and Benz rivals, but the GT is a perfect match for the RC 200t, while remaining good value for money. If you have your heart set on an Infiniti Q60 then I'd skip straight to the top and opt for the Red Sport.

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.

The Q60 GT is a head turner – literally. Whenever I was driving slow enough to notice, people were rubbernecking to look at the long, low-slung coupe. I'm sure most had no idea what brand of car it was, but in its 'Iridium Blue' paint the Q60 looked amazing with its curvy, sleek profile.

There's only one small issue – the RC 200t and Q60 GT are way too similar looking, right down to their 'signature' shaped c-pillars. I prefer the grille of the Lexus but the rear of the Q60. While there might be a bit of copy-catting going on, both are prettier than their BMW or Benz rivals.

The Q60 GT feels fairly large to drive and the dimensions don't lie – 4690mm end-to-end, 2052mm across with the wing mirrors unfurled, but low at 1395mm.

The cabin treatment is just as emotional as the exterior, with its dual screens, swoopy dashboard and sectioned off driver and passenger cells.

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 short answer is not very practical - but then no two-door sports car really is. So while the front two seats are roomy (although the optional sunroof restricts headroom) the same can't be said for the back seats – at 191cm tall, not only can I not sit up straight (because of the sloping roofline), I can't fit my legs in behind my driving position.

While those large doors open wide the roofline and the lack of rear doors means trying to insert a toddler into his car seat was painful and involved kneeling in the street, there were days we took our much less fancy SUV just because it was easier.

This is a four seater – with two cupholders in between the rear seats and two more cupholders up front. Storage elsewhere is limited, with tiny pockets in the front doors and a small centre console bin to hide your phone and wallet.

The boot is also on the small side at 341 litres – don't compare this to the 423 litre of cargo capacity in the RC 200t which is measured in VDA litres. That said, there was more than enough room for our weekly shop which fitted in snugly, although you have to hoist your shopping bags high to clear that boot lip.

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.

Kicking off at $489,900 plus on roads, it's fairly clear that the car the local operation has in its sights is the Ferrari 488 GTB, which sells for around $20,000 less but rarely arrives with less than $40,000 in options on board. Two further versions of the 720S are available from $515,080, the Luxury and Performance spec levels, both largely cosmetic.

The 720S ships with 19-inch front wheels and 20-inch rears wrapped in Pirelli P-Zeros. The exterior is finished in "dark palladium" trim and the cabin is lined with Alcantara and Nappa leather. Also onboard is a four-speaker stereo, digital dash, dual-zone climate control, sat nav, active LED headlights, power windows, sports fronts seats and not much else.

A predictably lengthy options list includes paint from $0 to $20,700 (McLaren Special Operations, or MSO, will cheerfully find ways to charge you more for that extra special paint job), but most of the list is carbon fibre bits, reversing camera ($2670!), a $9440 Bowers and Wilkins stereo... you get the picture. The sky, or your credit card, is the limit.

The front lift kit is $5540 and totally worth it to protect the underbelly from driveways. Unlike a couple of Italian rivals, it's not mandatory for all speed-bump ascents.

As we discover every time we look at a car like this, the spec seems slim but none of its competitors have much in them, so it's line-ball.

The Q60 GT has a 155kW/350Nm 2.0-litre four-cylinder turbo-petrol engine with drive being sent to the rear wheels through a seven-speed automatic transmission. The same engine is also in the Q60 Sport Premium, while the Red Sport packs a twin-turbo V6.

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.

An official combined fuel consumption figure of 7.7L/100km is fairly optimistic and our combination of urban, city and highway running saw the trip computer reporting back to us with 9.1L/100km. Still, that's not too bad considering how much time was spent in city traffic.

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.

I had a feeling this would happen - the GT was disappointing to drive after the Red Sport with the latter's twin-turbo V6, sports suspension, better steering and excellent Sport + drive mode. There's lots to like about the GT, though – the grip is great from the wide Dunlop SP rubber (235 40 R19 front and 255 40 R19 rear), the chassis feels taught, acceleration is good and it's a gorgeous looking car.

But there's a sense of disconnection from the driving experience I couldn't get past, such as the numb feeling in the steering which needed constant re-adjustment. I also think the suspension felt over sprung and lacked composure over small bumps in the road.

The GT and all Q60s don't have the same level of refinement as the C200 Coupe or 420i, evident from the clunky feel of the door handles to the road noise intruding into the cabin.

That 2.0-litre engine is great, but the transmission is a mood killer with it wanting to change up gears quickly to save fuel.

I'm not a fan of the cockpit. Sure it's brave and expressively designed, but the double-deck screens are confusing, there's one for nav, while the other's for media... I think. Then there are things you don't need, such as a digital compass – actually there are two, one on the display and another in the instrument cluster, but there's no digital speedo.

That 2.0-litre engine is great, but the transmission is a mood killer with it wanting to change up gears quickly to save fuel, even in 'Sport' mode.

Here's a curve ball call for you – I've just stepped out of a, Alfa Giulia Super. Close in price to the Infiniti, same sized engine, but infinitely more rewarding and fun to drive – plus you get an extra two doors.

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.

Along with a super-strong carbon tub, to which is fitted aluminium crash structures front and rear, the 720S comes fitted with six airbags, stability and traction controls and carbon ceramic brakes with ABS (100-0 happens in fewer than 30 metres).

The Q60 GT is covered by Infiniti's four-year/100,000km warranty.

Servicing is recommended every 12 months/25,000km. Servicing is capped at $538 for the first, then $643 and then $849 for the third.

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.
