Porsche 918 Spyder (37.8m)

The Porsche 918 Spyder is a car that scrambles your understanding of how a car performs on many levels, not least in how it stops. It pulls up from 70mph in less distance than any of its direct or near rivals, needing just 37.8m to stop, which is the length of about three London buses.

Porsche fitted 410mm carbon ceramic front discs and 390mm rear items, with the fronts 4mm thicker than the 32mm wide rears for better heat dissipation. The 918’s brakes also serve as part of the hybrid regeneration system, capturing energy that would otherwise be lost to recharge the car’s battery for EV-only driving. The 918 Spyder is the fastest stopping car we’ve ever tested.
