Lexus unveiled the all-new, next generation Lexus RX 350 and Lexus RX 450h hybrid at the 2008 Los Angeles Auto Show. The vehicle that pioneered the car-based luxury utility vehicle segment when it launched in 1998, is completely redesigned and will continue to set new benchmarks in areas that have made it the best-selling luxury utility vehicle: innovation, styling, performance, utility and comfort.
At the heart of the new Lexus RX models are two improved powertrains. Entering its second generation, the Lexus RX 450h will feature an enhanced Lexus Hybrid Drive system with a 3.5-liter V6 gas engine that runs on a highly efficient Atkinson cycle. Combined with a new, more efficient inverter, the total system output will be 295 horsepower, 27 more horsepower than the current generation RX hybrid.
Another step in the Lexus Hybrid Drive’s evolution is the addition of two new systems that improve its efficiency. The first is an exhaust-heat recovery system that reduces engine warm-up time allowing it to stop earlier, more often, and for longer periods. The result is an improvement in both fuel economy and emissions. The second is a cooled exhaust-gas recirculation system that reduces engine pumping losses, which also helps to improve economy.
