While the Lexus GS series isn't new, the GS 430 is. The 2001 model gets a new 4.3-liter 300-horsepower V8 engine with increased torque (now 325 foot-pounds). This extra boost propels the GS 430 to 60 mph in less than six seconds, and makes the V8-powered GS quicker than comparable models from Acura, Audi, BMW, and Mercedes-Benz.The six-cylinder GS 300 is no slouch either. With 220-horsepower on tap, the GS 300 goes from 0 to 60 mph in just 7.8 seconds.Click here to read more
