That cabin, then. Cramped, as a result of the aero changes outside? Not a bit of it. You do sit closer to your passenger, but the lower sills and the doors, which now hinge to all but vertical and take up a foot less width in the process, make getting in and out a fair bit easier – and with less head-bashing.
But the changes to the tub mean that the A-pillars are particularly thin (and left unadorned by trim), while thin carbonfibre beams criss-cross the original Honda-NSX-ish, Pagani-Zonda-ish looking occupant compartment, with glass panels everywhere making it a doddle to see out of. Not since the first NSX or, say, Ferrari 355 has a full-blown mid-engined supercar been so easy to see out of.
That airiness takes away any sensation that you might feel remotely cramped in here, and the rest of the cabin is a lot more accommodating. The driving position remains bang on as usual – dead straight, with one of the most adjustable steering wheels in motordom (connected to a rack that is still hydraulically assisted, incidentally).
Either foot will do for the centrally mounted brake pedal, and there’s a new pop-out instrument binnacle – a bit unnecessary – and a revised central stack, on which lives a new touchscreen controller (it’s far easier to use than the old Iris system), plus McLaren’s driving controls as usual, which remain slightly more complicated than they strictly need to be.
Still, it’s a nice place to be, with better materials. The stitching on the Alcantara on this pre-production car could be better in a couple of places, but on full-production McLarens, it usually is.
The point is, though, that the 720S is meant to be more broadly capable than the 650S. Better on the road and better on a track, although not quite as extreme as a 675LT when it comes to the latter. The 720S certainly rides well enough. It takes a certain confidence to hand a 710bhp supercar to a bunch of journalists who’ve never sat in it before and send them straight out into Monday morning Rome traffic, but there you go.
Visibility is terrific. The ride is compliant. The dampers still have three settings – Comfort, Sport and Track (with Comfort replacing Normal, because “there’s nothing normal about a McLaren”, don’cha know) – and you’ll leave them in Comfort most of the time.
The motor and gearbox have the same three settings, too, selected independently from the chassis ones. In town, the McLaren’s engine doesn’t shout loudly at you – even though our test car was one of the more racy specs, with a sports exhaust and also standard-sized fixed-back bucket seats (you can get wider ones, too).
Anyway, the engine. Not loud – not around town, at any rate. It’s powerful-sounding, sure, but there isn’t anything like the obvious grumble of an AMG V8 or the hollow ‘bwoap’ of something from Ferrari.
But it does seem to shrink around you pretty quickly, the 720S. Daft, really, how we sometimes sit and wonder, “How much power is too much?” Then you get in a £218k supercar and thread it through traffic and out beyond the suburbs onto crummy roads between fields, up and down gentle hills, and realise that it’s as easy to drive as a mid-level family saloon.
Only it’s quite a lot faster when you want it to be, obviously. There’s so much torque, with little noticeable lag, that it becomes second nature and an utter doddle to drive the 720S around in relatively high gears on the road, surfing the mid-range when you need an overtake, or three at once, enjoying the suppleness of the ride, which combines sweetly with the pure, oily slickness of the steering, which, at 2.5 turns between locks, is wonderfully geared and weighted, takes on reassuring midcorner weight and offers relatively uncorrupted road feel, like little else in this class.
Certainly, more than a Ferrari 488 GTB, and with less nervousness. It’s so easy to develop a flow, a rhythm. Yes, it has 710bhp, but as a McLaren bloke replied when we said how easy it was to drive a P1 on a circuit despite it having more than 900bhp: “Of course it is. You don’t have to use all the throttle.” Unless you want to, that is. We did, which is why McLaren had hired the Vallelunga circuit.
How much is too much? When does a car become uncontrollably powerful? Not yet. This is the utterly absurd, wonderfully ridiculous thing about cars like the 720S and, yes, the 488 GTB.
They take levels of power that a decade and a half ago seemed utterly crackers and install them into chassis so capable that you can be on full throttle, at the top end of fourth gear, in your second lap out of the pits, wondering what this fuss about too much power is all about.
The 720S is brilliantly approachable – yes, bonkers, ludicrously fast, but with a ride that, even on a far from smooth circuit and pulled into its Track mode, copes with bumps with superb absorbency while retaining mammoth control of its body.
There’s precious little dive under braking, little lean when turning and a thoroughly supported back end under acceleration. The steering’s weight remains consistent and pure, there’s genuine feel, gearshifts are crisp and the engine response is strong right through the range – no flat spots, no whoosh of turbo power that eases out as the revs rise towards 8000rpm, just broad, flowing, ever-increasing urge.
Does it sound special enough? Perhaps not, still. It’s a powerful sound, an appealing sound and, on occasion, a loud sound. But it’s not the reason to drive this car.
Throttle adjustability wouldn’t have been with a 650S, either. But now? Now, it is different. No, there is still no limited-slip differential, electronically controlled or otherwise, but there is so much power and brake steer does such a decent job of providing chassis adjustability that the 720S is responsive on the throttle.
There’s a hint of steadystate understeer, as you’d hope, but trail the brakes towards a corner, or lift mid-corner, and there’s genuine adjustability to the 720S’s moves. It’ll tuck in, rotate around a position that feels right next to your seat, willingly involve and engage you in choosing its angle and then slide – up to a small point if you leave the stability on, a bit further if you switch it half off and to varying degrees of side slip if you choose the Variable Drift Control, from ‘not really sideways at all’ to ‘quite sideways really’. But never as sideways as when everything is off, in which case the 720S will smoke itself up merrily.
