The RX 450h continues to serve as powerful reminders of the brand’s hybrid leadership, with 308 combined system horsepower for powerful performance and impressive EPA-estimated 30 combined MPG for RX 450h. The Lexus Hybrid Drive system pairs the D4-S fuel injection 3.5-liter V6 gasoline engine with two high-torque electric drive motor-generators for strong acceleration and passing performance. Instead of transfer gears and a driveshaft to the rear wheels, the all-weather drive system employs a second, independent electric motor to drive the rear wheels, when needed, to help maintain optimal traction.
