Like the Audi R8 and Porsche 911 Turbo, the 540C is supposed to be a usable supercar. That means that, although it’s the cheapest car in McLaren’s range, the 540C is actually fractionally larger than its siblings. The carbon tub has also been modified to lower the height of the sill, while the doors open wider. This makes the car much easier to clamber inside than a 650S. Head room is good despite the low roof and the interior is wide enough to prevent clashed elbows with your passenger.
Practicality may not be the main reason for buying one of these, but there is still a surprising amount of stowage space. Up front is a good-sized boot (bigger than that in the R8 or 911) and you can get a bag of golf clubs behind the seats. Inside, there’s an array of cubbyholes and a reasonably sized glovebox.
