The 2006 model line represented the third generation of the Lexus GS sedan. The totally redesigned GS 430 was left with only hints of the previous body style. The GS grew in every dimension: 2 inches were added to the wheelbase and one inch was added to the track width. The increase in overall length was marginal. The rear deck was considerably shorter and the heavily raked windshield and roof line gave the new body a sleek fastback appearance. The GS 430 housed the same engine as the late models of the previous generation, but that V-8 was now paired with a new six-speed automatic transmission. The 4.3 liter V-8 still produced 300 horsepower and 325 pound-feet of torque. The aluminum block DOHC engine was aided again by Variable Valve Timing + intelligence. VVT+i technology lowered emissions, improved fuel economy, and boosted power. Performance specs were mostly unchanged: the GS zipped from 0 to 60 in about six seconds, and fuel economy was observed at 18/23 mpg. The new generation still only offered an automatic transmission, but the tiptronic feature had returned. Because the GS consumed its fuel quite swiftly, many drivers expressed a longing for a larger fuel tank (tank was 18 gallons). Lexus had responded to the numerous complaints about ride quality, by adding variable suspension to suit a variety of preferences. Drivers who sought a true sports sedan experience were disappointed by the predecessor's soft and unresponsive ride. Although a firmer ride was now possible, drivers of the bulky GS reported some body roll when cornering. Priced comparably to the BMW 5-Series and Mercedes E-Class, the GS 430 had a polished and well crafted interior, supplied with all the amenities that one would expect.
