Latest model: Lexus RX 350 2010
Lexus represented the all-new, next generation Lexus RX 350 and Lexus RX 450h hybrid at the 2008 Los Angeles Auto Show. The car that pioneered the car-based luxury utility car segment when it launched in 1998, is completely refactored and will continue to set new benchmarks in areas that have made it the best-selling luxury utility vehicle: innovation, look-and-feel, performance, utility and convenience.

Lexus RX 350 details:
At the heart of the new Lexus RX models are two enhanced powertrains. Entering its second generation, the Lexus RX 450h will option an improved Lexus Hybrid Drive system with a 3. 5-liter V6 gas motor 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 enhance its efficiency. The first is an exhaust-heat recovery system that reduces motor warm-up time enabling it to stop earlier, more often, and for longer periods. The result is an improvement in both fuel efficiency and emissions. The second is a cooled exhaust-gas recirculation system that reduces motor pumping losses, which also helps to enhance economy.
The Lexus RX 450h features a front-wheel hybrid drive or an electronically driven, part-time all-wheel-drive (AWD) hybrid drive system, which supplies the back wheels with the optimal amount of torque as conditions demand. Unlike mechanical AWD systems that reduce fuel economy via added weight and friction, the RX 450h's rear-mounted electric motor-generator enables all four wheels to perform regenerative braking, charging the hybrid battery more effectively.
