The McLaren 675LT is insanity on wheels. Track focused, racing technology comes to the street in a package that is realistically the fastest road car money can buy for less than a million dollars. 666 twin-turbo HP, a curb weight under 3,000 LBS, and a lightning quick dual-clutch gearbox combine to form a car that is simply as fast as you can think. I'm convinced that even the million-dollar P1 is no faster on a public road than this rolling tribute to performance.
