McLaren has revealed the 675LT, the ultimate evolution of its Super Series supercars, ahead of its debut at the Geneva Motor Show in March.

Taking inspiration from the legendary F1 GTR Longtail racing car, the McLaren 675LT is lighter, faster and more aerodynamic than the 650S it is based on. McLaren claims around one third of the components are brand new.

Despite the name, the 675LT – i.e. ‘longtail’ – is only 34mm longer than the 650S. Instead, it refers to the new airbrake which is some 50 per cent larger than on the rest of the Super Series cars. Other changes to the car’s aerodynamics include a new front splitter and sculpted side sills.

There are extra cooling vents and larger air intakes to feed the much-modified engine. Half of the components are new, including the turbos, cylinder heads and manifolds, camshafts, conrods and fuel pump.

As a result, the motor produces 666bhp (675PS) and 516lb/ft of torque. That’s enough to dispatch 62mph from rest in just 2.9 seconds, with the 124mph marker passing in 7.9 seconds. Flat-out, the 675LT will be doing 205mph.

The changes to the engine also contribute to the 100kg weight saving over the 650S. Tipping the scales at a flyweight 1,230kg, the 675LT makes extensive use of carbonfibre for the body and lighter materials in the chassis and body structure. McLaren even found savings with a polycarbonate rear window, new rear valance design and by ditching the aircon (it can be put back at no extra cost).

Though it is completely road legal, McLaren says the 675LT is the most “track-focused” model it has produced, this side of the P1 GTR.

Prices are expected to start at around £260,000 when the 675LT goes on sale in June. More information will be released ahead of the launch.
