The 666bhp McLaren 675LT Will Do 0-62mph In A Neck-Snapping 2.9sec

The 650S is hardly a car that needs amping up, but that hasn’t stopped McLaren doing its best to turn it into an even more potent, weapons-grade supercar. The result is the 675LT, and although Woking expects you to stump up an extra £65,000 (the LT retails at a rather considerable £260,000) over the 650S, you get a whole raft of improvements for the added wallet pain.

50 per cent of the parts in the familiar 3.8-litre twin-turbo V8 are all new. It now puts out an extra 25bhp - 666bhp in total - while the torque figure sits at 516lb ft, up from 500. It now has less weight to shift, too: through the extensive use of carbonfibre in its construction, the 675 weighs 100kg less than a 650S. The new weight figure is just 1230kg.

This unsurprisingly makes the 675LT stupidly quick. It’ll do 0-62mph in just 2.9 seconds, and - perhaps more impressively - 0-124mph in 7.9. Crikey.

The name - as well as being a nod to the old McLaren F1 GTR Longtail - refers to the car’s active airbrake, which is 50 per cent larger here than on the 650S. On the aero front, the LT also sports a redesigned front bumper with a carbonfibre splitter, sculpted carbonfibre side sills and air intakes on the rear wheel arches.

The rear bumper is new, sporting a carbonfibre diffuser and a large exposed section in the middle where the socking great twin-exit titanium exhaust sits. This exposed area helps hot air escape from the engine bay as efficiently as possible.

The interior is a little more spartan than the 650S cockpit, featuring a pair of Alcantara-clad seats modelled on the same chairs you’d find in a P1.

Fancy a closer look? The 675LT will make its public debut at the Geneva motor show on 3 March.
