This is the McLaren 600LT, the fifth and most powerful model to be added to the British brand’s Sports Series range. It will be built by hand in limited numbers.
McLaren’s LT sub-brand, short for Longtail, is reserved for only the company’s most extreme models; only four cars have carried the badge, which started with the McLaren F1 GTR racer in 1996.
The 600LT follows on from the 675LT in 2015 and adopts that car’s mantra of more power, less weight and optimized aerodynamics. Under the skin the car is based on the 570S coupe but McLaren claims almost 25 per cent of the car’s parts are new or redeveloped.
The bespoke carbon fibre bodywork is the most obvious change over the standard model; the body itself has been stretched by 74mm thanks to a unique carbon fibre roof, front splitter, side skirts and extended rear diffuser. Top exit exhausts also appear along with a fixed rear wing to help reduce weight and improve downforce.
Changes continue inside where McLaren has fitted carbon fibre racing seats from the P1, which are trimmed in Alcantara. Buyers can go one step further and spec the even lighter carbon fibre seats from the new Senna. The British firm claims with every lightweight option fitted the 600LT weighs up 96kg less than a standard 570S; without fluids the car tips the scales at 1,247kg – you can another 150kg with a driver and fluids on board.
Like all of McLaren’s road cars the 600LT is power by the brand’s twin-turbocharged V8 engine. The 3.8-litre unit has been tweaked to develop 592bhp and 620Nm of torque. McLaren hasn’t gone into specifics about how the power hike has been achieved over the 570S but a new cooling system and reduced exhaust back pressure play part. Performance figures are yet to be issued but expect a 0-62mph of around 3.0 seconds.
Chassis tech from McLaren’s Super Series model, the 720S, has also been adopted and developed for the 600LT; forged aluminium double-wishbone suspension, a carbon ceramic braking, stiffer engine mounts and Pirelli Trofeo R tyres are all designed to bring better ‘track focused dynamics.’
McLaren hasn’t confirmed how many 600LT models will be produced, but it will be built in ‘strictly limited numbers’. Only 500 examples of the previous 675LT coupe were made, which were later followed by 500 examples of a 675LT Spider. It’s likely McLaren will take a similar approach with the 600LT.
