Hear the McLaren 675LT and its titanium exhaust pipes roar

McLaren, you big tease. First the British manufacturer told us to expect 666bhp of tarmac-shredding power, now it has let slip what generates all that power and how it could sound.

Underneath the bonnet is a ‘heavily revised’ 3.8-litre twin-turbo V8 engine that pushes out a staggering 516lb/ft (700Nm) of torque. McLaren says the engine features lightweight components and new turbos but is yet to elaborate further on the specifics.

Power is limited to 443lb/ft (600Nm) in first gear to ensure traction and acceleration is optimised. Every other gear gets the full whack from 5,500 to 6,500rpm.

At the back is a twin-exit exhaust system. No stainless steel is used here, McLaren has instead opted for titanium to save weight and ‘optimise performance’. What really matters, of course, is what 666 horses sounds like, which you can find out in the video below.

Still here? Then you probably should know the 675LT is be an interpretation of the F1 GTR, which was essentially a longer, racier version of the F1 supercar. The F1 GTR was nicknamed ‘longtail’ because it was longer. In the 675LT, LT refers to an airbrake at the back of the car that improves downforce by 40 per cent overall. Got it?

The 675LT joins the 625C and 650S Coupe and Spider in McLaren range, which is now comprised Sports Series and Super Series. The P1 hybrid hypercar sits in its own category of insanity.

Expect to hear just how fast it goes and other drool-worthy details as we head to the Geneva Motor Show in March. Read our collection of words on the 650S here.
