There’s no noise inside the cab of the Lexus LS 600 hL, and while that may not be news for a Lexus, it’s news when they claim it to be the quietest car ever. That’s a tough claim to make, but it just may be possible, given what Lexus claims is an extensive re-engineering of gears and motors, designed to produce virtually zero intrusive sound elements. They say that even the engine is silent, which is something some folks may not like too much.

As a long wheel base only model, the Lexus LS 600 hL offers a full array of luxury for passengers, including reclining back seats, foot rests, and massage for all. It has almost five inches more rear seat legroom than the new LS 460. For both cars, there’s a 19-speaker stereo system, and all models of the LS will offer XM for the first time in a Lexus vehicle.
