What is it?
To get an idea of how far McLaren has come with the new 720S, just get its engineers onto the subject of what’s left – how they’ll possibly outdo this car when the time comes.
That, they’ll say with a sigh, is the question. When they introduced the 675LT, even the 650S, they already knew this was coming. They knew what the 720S – P14, in McLaren’s development speak – would be able to do and they knew how much further ahead of both the 650 and 675 it was, in all areas.
They put so much into the 720S that now they’ve got nothing left in the tank. This car, make no mistake, feels a generation and a half on from a 650S. It’s so fast, so usable and so controllable that it might – just might – be the best supercar on the planet.
I’m getting ahead of things.
So, 720S. McLaren’s naming structure is now familiar, and it won’t be the only familiar thing about this car if you follow sports cars. Because it’s both a supercar and a McLaren, it comes with certain engineering characteristics.
It’s mid-engined and rear-wheel drive and has a twinturbocharged V8 engine. It has a carbonfibre tub, albeit a new one, whose integrity now stretches over the occupants’ heads, increasing rigidity and, because it removes steel from the top of the structure – the windscreen surround, for example – it’s now 18kg lighter than before and lowers the centre of gravity.
In front of that is double wishbone suspension; ditto at the rear. That’s linked front to back and side to side by McLaren’s hydraulically connected damper system, Proactive Chassis Control II, which is improved with the addition of new sensors but still baffles the heck out of mutton-headed old mugwumps like your correspondent.
In short, it gives stiffness in roll conditions and compliance on rough roads, and it negates the need for anti-roll bars. If McLaren’s Super Series cars to date have had anything in common – MP4-12C, 12C, 650S and 675LT – it’s that their ride quality has been uncommonly good.
