It's been quite a week: the new Ferrari 488 GTB, Porsche Cayman GT4, and Ford Focus RS. All three will have their official live debuts at Geneva early next month, but there's another hot ticket item we're anxious to see: the McLaren 675 LT. The UK supercar builder has released a few teasers so far, but major details were obviously left out. But here's what we know: essentially a lighter, more powerful 650S, "LT" stands for "Longtail," a now legendary F1 GTR race car that competed back in the late 1990s.

The number 675 refers to its output: 675 PS, or 666 horsepower as well as 516 lb-ft of torque from that familiar twin-turbo 3.8-liter V8. Along with the greater output, expect to see plenty of new aero bits for increased downforce. There's also new lightweight engine components such as new turbos and a titanium exhaust. The 675 LT will be a street legal, coupe-only supercar and sales will begin sometime later this year as part of McLaren's "Super Series" range. Being "the lightest, the quickest, the purest version in (that) range," the 675 LT will square off directly against the likes of the Porsche 911 GT3 as well as the Ferrari 458 Speciale. Full details and official photos are coming soon.
