What is it?
It’s the McLaren Senna, and it’s quite a serious proposition. “We wanted to create the ultimate road-legal track car,” says Andy Palmer (no, the other one), McLaren’s Ultimate Series director. It’s a carbonfibre tubbed, 789bhp, £750,000 track-focused car.
There will be 500 of them, fully homologated as a series production car for worldwide sale (the ones we’ve driven are still, technically, prototypes). It happens to make 789bhp, or 800hp, and an accompanying 800kg of downforce at 155mph. Hence the rear wing and the rest of the – shall we say – ‘challenging’ looks?
A Senna won’t take long to reach the 155mph McLaren measures downforce at, either. McLaren is usually accurate with its acceleration quotes: it says 0-60mph takes 2.7sec, 0-124mph 6.8sec and 0-186mph just 17.5sec. The top speed is 211mph. You can add to the three-quarter million pound price quite easily too, via a visit to McLaren Special Operations (MSO) for bespoke extras.
Virtually all customers will have done so for this Ultimate Series car, although don’t take that description too literally: there’ll be a further 75 track-only GTR Sennas; lighter, more powerful again. And then presumably somebody like Lanzante will do a roadgoing version of that.
Another, perhaps even more significant, number is the 1198kg the Senna weighs (before fluids). The previous Ultimate Series McLaren, the P1, weighed 1395kg in similar trim, owing to its hybrid tech. The current 720S weighs 1283kg dry.
