Introduction
The RX 450h is the luxury hybrid crossover SUV from Lexus, which is redesigned for 2010 and replaces the RX 400h, which has been the top trim level of the RX lineup since it debuted for the 2006 model year. The new RX 450h designation is indicative of the updated Lexus Hybrid Drive, which delivers 295 horsepower and improved fuel economy. The 3.5-liter V6 engine adopts the Atkinson-cycle combustion system, and the 288-volt DC nickel-metal hydride battery pack is lighter and more compact. Available with all-wheel drive or front-wheel drive, the redesigned RX 450h features a new version of the Lexus L-finesse design language while retaining the distinctive RX appearance. The original Lexus RX 300 was the first luxury crossover SUV when it arrived in 1998 as a 1999 model, and the RX 400h followed as the first luxury crossover SUV hybrid.
