McLaren 720S Spider Review

A car capable of putting a 200mph breeze across your bonce. Or perhaps more pertinently the roadster version of our favourite current supercar, McLaren’s 720S. Now, you know the score. Take supercar, remove roof, receive roadster. Only it’s never that simple because 700bhp supercars need to be stiff, and so in addition to the roof’s motors and panels, they need extra bracing and strengthening. End up weighing 150kg more.

You’re one step ahead of us, no doubt. McLaren’s dedication to a super-stiff carbon fibre tub instead of the aluminium monocoque used by almost all rivals means weight gain is kept to a minimum – just 49kg here – and strength isn’t sacrificed. That’s not to say both use identical Monocage II tubs. No, McLaren had to slightly alter the header rail to incorporate a central securing latch for the retracting roof.

OK, there’s a bit more to it, which has led to the 720S Spider’s chassis tub gaining an extra letter. This is now Monocage II-S. The changes mainly incorporate a new carbon rear section behind the seats (basically a frame for the roof to fold into) and alterations to the hinges and sealing as the door glass is now frameless.

The roof. Moved by electric motors rather than hydraulics, so it’s quieter. And it moves fast, too. Just 11 seconds to complete the sun vs rain routine. And at up to 31mph. McLaren is so proud of this lid, it’s applied for three patents on it.

The 720S coupe gained a reputation for habitability, thanks in no small part to excellent all-round visibility. This is an area roadsters typically perform badly in – somewhat ironic in a car designed to deliver maximum fresh air potential. But McLaren claims to have worked hard to keep the back deck low and that the glazed buttresses improve over-the shoulder visibility by literally some per cent.

Otherwise McLaren has copy/pasted coupe to roadster. Same hydraulic cross-linked variable dampers and active aero package (although your top speed is ‘only’ 202mph with the roof down, 212mph raised), and the 4.0-litre V8 twin turbo is carried over unchanged. But that’s still 710bhp and 568lb ft to do the shoving, so 0-62mph takes 2.8secs and 124mph is dusted in 7.9secs. The Coupe is obviously faster… but only by 0.1secs to 124mph. Basically nothing.

The biggest gain therefore is not the additional 49kg, but the fact McLaren charges £580 for each of those kilos. Yep, while the coupe starts at £208,600, base price for the Spider is £237,000. And like the coupe, most buyers upgrade to either Sport or Luxury specification (£246,990). And then use that as a jumping off point to greater things. Like the eleven carbon fibre option packs fitted to the car you see here that together add another £42,490, helping boost the total list price of this Luxury spec car to £321,900. Ouch.
