MAC AIR

Despite offering none of the trick moveable aero structures of the 720S, the 600LT works the air hard. The front splitter juts forward by an extra 27mm, and there’s an 8mm drop in ride height. Brake cooling channels are set into the floor, and the flanks of the car are garnished with carbonfibre splitter end plates, tyre spoilers, side skirts and aero winglets.

Exiting the twin exhausts skywards from the revised mesh engine deck has allowed Mclaren to go wall-to-wall with the massive rear diffuser. As well as being wider, the diffuser is longer, starting under the rear axle. This length helps create a low-pressure zone under the vehicle, diffused more gradually into the airstream. At 255km/h, 100kg of downforce is split 40 percent front, 60 percent rear.
