The original LS400 was the first Lexus to market in 1989. It was also the one mostly responsible for the almost shocking speed with which this upstart nameplate achieved parity with other premium brands that were backed by decades of pedigree and heritage.

Maybe the LS wasn't a great enthusiast's ride, but in the virtues that really mattered for a luxury sedan, it was supreme.

Three generations later, where is Lexus going with the LS? You could say: "all-out." Competing in the elite division of the car market, the LS showcases everything Lexus knows -- and in the process tries to one-up the opposition.

So, Mercedes has a 7-speed automatic? The LS460 introduces the world's first 8-speed. BMW has active stabilizer bars? The LS460 can park itself automatically. Mercedes offers massaging seats? The LS ones do Shiatsu.

There's more: A separate climate-control system for the rear seat; Audio with up to 19 speakers; Headlamps that look like they're cut from crystal; And a power reclining back seat with an ottoman ...

Oh yes, there is an engine, though you may not be able to hear it. The all-new 4.6-litre V8 punches out 380 hp -- just two fewer than an S550's 5.5-litre V8. And it goes without saying that the chassis employs every form of control-and-assist electronic nanny yet devised.
