The technical resumé of the Lexus LS 460 reads like a Ray Bradbury novel. A keyless entry keycard that's actually the size and shape of a card. A climate control system that tracks occupant body temperature. A 19-speaker Mark Levinson audio system capable of holding 4,000 songs on an internal hard drive. And if your neighbors still aren't impressed, let them just try to ignore the LS 460 as it parks itself. Beyond the science fiction aspect, this is the first time Lexus has offered its flagship sedan in two different wheelbase lengths, with the "L" version providing an additional 6 inches of rear legroom. Both versions come with an ultrarefined 4.6-liter V8, good for 380 horsepower and 370 pound-feet of torque.
