The 620R is a 570S GT4 race car returned to the road: the racer's aero, adjustable dampers, and the 3.8-liter V8 freed to 611 hp — the output the GT4 rulebook restricted. McLaren built it in a strictly limited run as the Sports Series finale. Road-legal customer-racing hardware of this kind reaches the street rarely, which is precisely its appeal.
