McLaren has released the performance figures and all the details of the new 600LT ahead of the model’s world debut at the Goodwood Festival of Speed.

The 600LT is the lightest, most powerful and capable road-legal Sport Series model ever.

With the revised twin-turbo 3.8-liter V8 providing 592hp (600PS) and 457lb-ft (620Nm) of torque and a reduced, by 96kg (211lbs), curb weight compared to a 570S, the new 600LT is capable of completing the classic 0-60mph in 2.8 seconds (0-100km/h in 2.9), matching the 675LT.

Moreover, the new Macca will achieve the 0-124mph (200km/h) sprint in a very impressive 8.2 seconds, which makes it faster than the Ferrari 488 GTB by 0.2 seconds. Top speed is set at 204mph (328km/h).

The new member of the very exclusive LongTail family features a revised bodywork that includes an extended front splitter, lengthened rear diffuser and a fixed rear wing, making it 74mm longer than the 570S. The model-specific bodywork improves the aerodynamic performance in conjunction with the flat carbon fiber floor in order to produce 100kg of downforce at 155mph (250km/h).

Customers will be able to spec their 600LT with the optional Clubsport and Clubsport Pro packs for even lighter weight and a more track-focused character. The former is a £24,170 option and adds a set of lightweight carbon fiber racing seats, a carbon fiber interior upgrade that includes extended gearshift paddles, carbon fiber roof and fender louvers, titanium wheel bolts and more. The Clubsport Pro costs £28,480 and adds a harness bar and six-point harnesses for track use.

The chassis has been upgraded with lighter and stiffer suspension components from the 720S, while ride height has been reduced by 8mm and the front track has been widened by 10mm.

The suspension utilizes a set of re-engineered variable adaptive dampers and anti-roll bars in order to perform better with the new suspension geometry. The brake system features lightweight brake calipers and stiffer carbon-ceramic disc, as well as a Senna-inspired brake booster. There are two new designs for the ultra-lightweight alloy wheels, which are shod in bespoke P Zero Trofeo R tires.

Of course the biggest highlight is that kick-ass top-exit exhaust that reduces back pressure and, according to McLaren, is “more extreme than that of the Senna”.

McLaren will start production of the 600LT this October. The company says that availability will be “strictly limited”, thanks to the new body panels requiring specialist tooling, but didn’t say how many it will actually produce.

Customers can order the new McLaren 600LT now -subject to availability-, with prices in the UK starting from £185,500.
