After a poke around this most extreme of cars, I have to say it is jaw-dropping, even if it is not as beautiful as the P1 or F1 that have carried the standard for McLaren in the past. I’ve no quibbles with that, either: the fastest McLaren ever it may be, but nobody is promoting it as the successor to either of the aforementioned icons.
Most striking are the front splitter and rear diffuser, which look scarcely credible and would be barred from any racing championship, but which McLaren has been able to exploit on account of the car being essentially a track-day special.
These addenda are incredible not just for their sheer size, but also because you could quite reasonably point at them and say “not even an F1 car has that kind of tech on it”. For an owner, I imagine that kind of wide-eyed brag is really quite appealing. For the watching world - and I suspect a legion of excitable kids and young adults - it’s the sort of thing that makes you stick a poster on your wall (or download it as a screensaver, or whatever they do these days).
Combined with the giant rear wing and the brutal, no-holds-barred design language of the standard Senna, it makes for a car that is striking in every sense. Like the road-going version, it won’t be to everyone’s tastes, but it is undeniably purposeful.
It is also, in many regards, unique. For McLaren to label the Senna GTR as the fastest thing on a track bar a Formula 1 car is quite a striking claim, and one that should bring to mind comparisons with the Aston Martin Valkyrie and Mercedes-AMG Project One. And yet, at £1 million (plus taxes), the Senna represents something of a bargain compared with those two.
It is also, McLaren personnel promise, being conceived as a car that can run at a track day without the need for any technical assistance. As one member of the management team said: “An owner might want someone to change their tyres for them, but there’s no reason why they won’t be able to do it themselves.”
