Colin Chapman, the founder of Lotus, famously said, “For speed, add lightness.” In age where many supercars are too big and heavy for their own good, McLaren are one of the few manufacturers who take low weight seriously.
Their new 600LT is a case in point, and is based on the 570S, the sweet spot in McLaren’s mid-range Sports Series range. The 600LT is 96kg lighter than a 570S with an extra 30hp, and 100kg more downforce, the 1,274kg dry weight delivering a power-to-weight ratio of 481hp/tonne.
Lower weight, improved aero, bigger brakes and state of the art rubber; all of these engender more speed along with better handling and grip without the need for a major increase in engine power. And lower weight means less loading on the engine for better fuel economy and emissions.
Since most enthusiasts want to know a cars power and performance before anything else here goes. A modest increase in boost pressure within the ECU remap and lower back-pressure from the new top exit exhaust system sees the output of the 570S M838TE motor rise from 570hp and 600Nm of torque to 600hp at 7,500rpm, with 620Nm of torque from 5,500 to 6,500rpm.
