Here’s an example chosen not entirely at random. If you’d read our full road test of the McLaren 650S in print last month, the observant may have noticed something they weren’t expecting in amongst the usual detailed performance numbers: specifically, benchmark laptimes.

And not just for the McLaren, but also for the Ferrari 458 Speciale – which you’ll be able to read an equally detailed full road test on in a couple of weeks.

So, just to add further context to the missive you might have read from Steve Sutcliffe the other week – Maranello was more than happy for us to circuit test its new extra-sharp 458, and to set a laptime we could compare with that of a 650S.

And, conveniently but entirely genuinely, both cars lapped MIRA’s Dunlop circuit in 1min 08.3sec: only three tenths off our old lap record (Radical SR3 SL), which the McLaren P1 smashed into a million pieces earlier this year. Same driver, same ambient temperature, same conditions, different days. 

So that’s that. In the end, after all the maneuvering, permission-seeking, permission-denying and complaining, these two supercars set identical fastest laps – to the tenth. 

And as usual, those laptimes in themselves end up signifying almost nothing, and informing our impressions of these cars in very tangential terms indeed. The better track car is the Ferrari – which is also the slower car in a straight line, as it happens.

The better road car is the McLaren. Given the choice, I’d have the former – but that’s in part because I like the single-mindedness that such purposeful track cars tend to show.

So why wouldn’t Ferrari let Steve’s video comparison go ahead? The reasons are actually too convoluted and boring to detail, but here’s a flavour.

Ferrari likes to know in advance when their cars are going to be driven on a track – not, I believe, because they habitually supply unrepresentative cars to us, but because they like to be consulted. They like to buy in. They have a duty of care. They didn’t get enough notice of Steve’s Castle Combe circuit test; the right people weren’t given a reasonable chance to say ‘ok’ in advance. Simple as.
