The 540 and 570 are part of the Sport series at McLaren. These “entry-level” models from the British brand compete with the Mercedes-AMG GT, Porsche 911 and Audi R8. The 540C, 570S and 570GT coupes and the 570S Spyder convertible share the same mechanical features. Under the hood (or more precisely, the rear hatch), there's a twin-turbo, 3.8L V8 that sends power to the rear wheels by way of a seven-speed gearbox.
