Hybrid Synergy Drive

RX 400h's powertrain consists of a 3.3 liter 24 valve double-overhead cam V6 gas engine that teams up with an electric motor to deliver 268 hp. The gas engine produces 212 lb-ft of torque; the electric motor adds 247 lb-ft of torque to the front wheels from 0 - 1500 rpm. Coupled with a Continuously Variable Transmission (CVT), there's no jolting as gears shift -- there are no gears in the automatic transmission, just a set of pulleys that keep the engine in the powerband.
