The Lexus LS flagship comes in a regular length and a long-wheelbase L version. Its V8 is mated to an eight-speed automatic transmission -- the first ever in a passenger car. Other options include a precollision system with radar-based cruise control, a 19-speaker stereo with an eight-gigabyte hard drive, cooled rear storage, a reclining rear seat with massage, leg rests and rear seat heaters. The end result is a supremely pampering car that isolates its occupants and is fuss-free in every way -- but it is not a driver's car. All-wheel drive is optional for non-hybrid models.
