here if required), its overhauled engine, new Proactive Chassis Control and reduced weight thanks to a Monocage (instead of a Monocell). And, well, its styling too.
Do you like it yet? Away from a racetrack crammed with them, the 720S looks impossibly dramatic just pottering around Sussex villages, a full-on supercar and, even in brown, properly exciting. There's so much going on to draw the eye in, various louvres, intakes and gills, the whole thing a fascinating amalgam of science and style. It's better away from a motor show stand and certainly to these eyes more appealing in a darker colour - another mention for brown - but, to be honest, a 488 GTB is still a bit prettier. Sorry.
That's not only an apology because it's a hugely subjective judgement, but also because so much of what the 720S does is damn near brilliant that a criticism looks almost churlish; a complaint for the sake of it, to deny it a flawless report card. There are other minor quibbles, in fact, but we'll save those for later.
For the first few miles on the road, while for all the world you're trying to think about the Monocage, the Proactive Chassis Control and the new infotainment, the performance still dominates. In an all consuming, unrelenting, inescapable way - you can think of nothing else but how this McLaren accelerates so furiously. Need numbers? This car has been timed by Autocar to 100mph in 5.6 seconds, or faster than a Civic Type R gets to 60mph. Seriously.
There's still plenty to enjoy should a police car be heading up your queue of traffic though. Isn't it annoying when that happens? This is certainly a more focused car than the 650S; it's still very comfortable to pootle around in with the Active Dynamics Panel dials set to their most relaxed, yet it lacks the spooky ability of the old car to feel like it's driving on porcelain. It's definitely a well set compromise, the 720S always involved but not overly intense and - cliche alert - works beautifully with a British B-road. Whether you're behind a police car, a tractor, or have a few minutes to yourself.
The steering is still fabulous, detailed and delicate at all speeds. The weight of both pedals could not be improved and being able to see out so well is great for boosting confidence. Because of what the car is telling you, what you know about the car and what you can see of the road, you're very swiftly put at ease in the McLaren. Which seems an absurd statement to write about a rear-wheel drive, 720hp car - they might be more common than ever, but surely they must still be spiky and awkward?
That's of course a familiar, bordering on the repetitive, observation about McLarens now. What's key with the 720S though is that the bar has been raised everywhere: it's more visceral, more engaging, more involving. Oh yes, and faster. Ally those attributes with a gorgeous interior and, as mentioned on the launch, increased track ability, and you have a supercar of incredibly broad reach and appeal. This is all McLaren knows and does well, from 570GT to P1, distilled and concentrated into one package; if you've read or seen anything of what's been wittered on about those in the past few years, you'll know what an awesome end product the 720S therefore represents.
And those niggles? The infotainment screen is vastly improved from before, but it's still not perfect. One or two graphics looked a bit low rent and the sat-nav mistook a bridleway for a road on our brief drive. And despite the enhancements, it would be a stretch to call the engine a true great as the 488's is that bit sharper again. Crikey is it close though.
As for choosing between McLaren and Ferrari, it would be impossible without a direct comparison. And that's not going to happen any time soon. Right now, fairly fresh from the drive and totally enthralled by it, the 720S would just get the nod; tomorrow it could be the Ferrari - it really is that tight. Whatever, both are staggering, superlative, sensational supercars that would be a joy to own; and that's an absolute pleasure to write.
