Among the changes that McLaren has made for the Spider is to drop the clumsy “MP4” part of its moniker, so that it is now simply titled 12C Coupe or, in this case, Spider.
Visually, the attachment of a folding solid roof has precious little difference to the lines of the 12C. It is still, to our eyes, a relatively attractive shape and one which is ageing gracefully enough, but one that even now gets people looking because it’s a McLaren, not looking because of the way it’s designed.
Then, McLaren has always been a company to err on the understated side of things.
Efficiency of performance is more of a McLaren trademark, so you’ll probably not be surprised to learn that the numbers on structural rigidity of the roofless 12C were all worked out well in advance of the coupe’s launch and that, even though the twin-panel roof mechanism adds 40kg, it takes away not a jot of the torsional stiffness of the 12C’s carbonfibre tub.
Away from the roof mechanism – whose panels and the engine cover are the only body panels that separate the Spider from the Coupe - things stay mechanically identical to the fixed-roof variant. Similar, then, but in detail ever so slightly different to 2011 models.
