Top Gear writes on Lexus bringing the new Lexus LS460 to the British Motor Show:

"Packing a 4.6-litre V8 engine with 375bhp, the LS460 puts this power down through the world’s first eight-speed automatic gearbox. "

Lexus owners club has more info on the Lexus LS460 and more pictures, though it reads more like a press release than a review. Quite a car though.
