Except for badging and a specific airflow vent design, the 2007 Lexus GS 450h looks identical to the regular 2006 GS models. Other differences include 18-inch alloy wheels and a power meter that replaces the tachometer. With its attention to high, dramatic beltlines, swooping curves and taut points of reference, the Lexus GS carries a refined, emotive design sure to please luxury buyers.
