2006 Lexus GS

The Lexus GS 300/430, completely redesigned for 2006, is in pursuit of the BMW 5 Series's benchmark balance of sport and luxury, but doesn't quite reach it. Our GS 430 had 300 horsepower and a quick, responsive six-speed sequential-shift automatic, both of which would suggest sport-sedan entertainment. Not so. This is a car that feels like it's not sure how to properly straddle the sport/luxury fence.

Along with the big power and quick-shifting transmission, the new Lexus has a poised chassis and a well-engineered suspension, yet the car doesn't allow the driver to utilize them. Default settings in place, it doesn't take all that much to make the safety systems "correct" enthusiastic driving. A button allows you to turn off the traction control, but the system automatically reengages above 30 to 35 mph. ESP can't be turned off at all. The odd effect of the electronic limiters is to allow the car to generate impressive performance numbers, including 6.4 seconds to 60 and a 64.4-mph slalom speed, without being fun to drive.

On the luxury side of the equation, the GS is certainly not lacking. Exterior styling gives it a much more streamlined, attractive appearance than its predecessor. Its ride is pleasantly compliant, without feeling too Buick-like. The cabin is well isolated from road noise, materials are soft to the touch, and the seats are a good compromise between comfort and support. Also, the interior contains plenty of high-tech gadgets to keep a new owner's digits busy. However, the strongest evidence that the GS now leans toward luxury and away from sport is the engine options: There's either a 245-horse, 3.0-liter six or the aforementioned V-8. The smaller, lighter IS comes with a 306-horsepower, 3.5-liter V-6 that trumps even the GS 430's 300 horses. Perhaps this is statement enough of what the GS is--and isn't--supposed to be.
