The 2010 Lexus RX 450h, which replaces the old RX 400h, sports the same lines as the fully-redesigned RX 350. Yet it stands out from this gasoline model with subtle tweaks to the front grille (including chrome slats), a thin, horizontally-stretched opening under said grille, revamped fog light clusters as well as vivid blue-accented headlights, taillights and logos.
Similar to the RX 350, the hybrid variant rides on 18-inch alloy wheels (or 19 inches optionally). But unlike its predecessor, the combustion engine uses an Atkinson thermodynamic cycle instead of an Otto cycle. Therefore, it operates more like the powertrain of the Toyota Prius and Ford Escape/Fusion Hybrid.
