The McLaren 600 LT will make its dynamic world debut at the Goodwood Festival of Speed this coming weekend. The British sportscar specialist has been drip-feeding us with info and pics of its new model for weeks. Now, McLaren has released full info on the 600LT and the numbers are impressive.

Extreme performance

McLaren says that the 600LT is the quickest, most extreme road-legal Sports Series McLaren produced to date. We already know some of the headline figures. The retuned and recalibrated 3,8-litre twin-turbocharged V8 produces maximum power of 442 kW at 7 500 r/min along with 620 N.m of torque. This, coupled with a dry mass of 1 247 kg, results in a power to mass ratio of 354 kW/ton.

In part, the low mass, somewhat lower than most competitors, is a result of the extensive use of carbon-fibre. If the 100 kg mass-saving over a standard 570S isn’t enough, then buyers can opt for The MSO Clubsport Pack that features the lightweight carbon-fibre racing seats; a carbon-fibre interior upgrade that includes extended gearshift paddles and carbon-fibre roof and cantrails, and titanium wheel bolts. The MSO Clubsport Pro Pack, adds a harness bar and 6-point harness for track use, in black, blue, red or McLaren Orange.

Lightning quick

McLaren’s performance claims for the 600LT almost read like those of a supercar. The 0-100 km/h sprint is dispatched in 2,9 seconds while getting to 200 km/h from standstill takes 8,2 seconds. Top whack is quoted as 328 km/h.

To harness that power the 600LT adopts the braking system from the McLaren Super Series. Lightweight aluminium calipers and stiffer carbon ceramic discs, reduces mass by 4 kg. McLaren claims that the 600LT can brake from 200 km/h to standstill in 117 metres – just 1 more than a McLaren P1.

Stability and control

To harness the uprated power the 600LT uses a bespoke suspension layout. Forged aluminium double wishbones and uprights not only improve dynamic capabilities but also reduce weight by 10,2 kg. A lower ride height and wider track also help stability. New, lightweight alloys are shod with grippy Pirelli P Zero Trofeo R.

Unique bodywork employed on the McLaren 600LT, in conjunction with the flat carbon-fibre floor produces 100 kg of downforce at 250 km/h. The increased stability at high speeds adds to driver confidence during cornering.

Bare bones

As befitting a track focussed machine such as the McLaren 600LT air-conditioning, satellite navigation and the audio system have all been removed. Though if you feel any of those is required McLaren will throw them in free of charge. The glovebox and door pockets have been replaced with lightweight nets.
