2010 Lexus RX 450h and RX 350

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.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 rear wheels with the optimal amount of torque as conditions demand. Unlike mechanical AWD systems that reduce fuel efficiency via added weight and friction, the RX 450h’s rear-mounted electric motor-generator allows all four wheels to perform regenerative braking, charging the hybrid battery more effectively.

The third generation Lexus RX 350 will be powered by an improved 275-horsepower, 3.5-liter V6 engine mated to an electrically controlled, sequential-shift six-speed transaxle. The all-wheel-drive version will feature an Active Torque Control AWD system that optimizes torque depending on driving conditions, resulting in improved efficiency and performance.

Both RX models feature a new, uniquely designed double-wishbone rear suspension that helps provide exceptional agility and control. Its distinctive design also allows for five percent more cargo volume and easier loading. To complement the new rear suspension and provide excellent dexterity and ride comfort, the front McPherson strut geometry was optimized.

The all-new 2010 Lexus RX 350 will go on sale February 2009, while the 2010 Lexus RX 450h will reach dealerships nationwide in the spring.
