RX 400h GS 450h LS 600h L
World's First Luxury Hybrid SUV

The first luxury SUV to combine a traditional gasoline engine with electric drive, the RX 400h generates strong torque for excellent low- to mid-speed acceleration and is equally at home in the fast lane.

Available in front-wheel-drive and all-wheel-drive configurations, the RX 400h delivers powerful acceleration comparable to that of its V8 competitors, while achieving a combined fuel economy ranking akin to many four-cylinder compact sedans. It also carries a Super Ultra-Low Emission Vehicle (SULEV) rating.

The "400" stands for the equivalent engine displacement achieved through the combination of a 3.3-liter V6 gas engine and electric drive motor, which approximates the power output of a 4.0-liter V8 engine.
Inside, the RX 400h achieves a subtle and soothing balance, with leather-trimmed interior and brushed-aluminum accents or available wood trim.
High Altitude Performance
The RX 400h enjoys excellent performance at high altitudes and in mountain driving. Traditional gasoline-powered vehicles may suffer from decreased performance at higher altitudes where there is less oxygen in the air. Because the power output of the hybrid battery is not directly affected by altitude, the RX 400hs acceleration performance can be less affected by altitude than that of a conventional vehicle.
