The newest MT900 weighs a scant 2,275 pounds while putting out 550 horsepower; the car is expected to sprint to 60 mph in less than three seconds. The Mosler team says the Photon has a chance to best its own 2:45.9 record on the 4.1 mile lap from 2008. (Incidentally, last year's best lap time, set by a Lamborghini LP670-4, was eight freaking seconds slower.)

Mosler Vice President Jill Wagner has already made a few boasts: The MT900 Phantom will blast the aforementioned sub-three-second zero-to-60 time; will reach a top speed of 210 mph; will outbrake and outcorner all other U.S.-legal supercars; and will finish the lap in the 2:40 range. Oh, and do all that while consuming 40 percent less fuel than the other supercar competitors. Guess we'll have to wait until Oct. 7 to find out if Wagner is correct on any, some or all of those claims.
