Except for badging and a specific airflow vent design, the GS 450h looks identical to the regular 2006 GS models. Other differences include 18-inch alloy wheels and a power meter that replaces the tachomter. This design, which is new for Lexus, comes from the LF-A supercar concept and will be carried over throughout the lineup. 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.
