We have developed the new SPORT HYBRID SH-AWD system, a hybrid system that provides best in class fuel economy and drivability to exceed customer expectations.The powertrain has a V6 engine and comes with three drive types modes: front wheel drive powered by a 7-speed dual clutch transmission with one built-in motor, rear wheel drive powered by a twin motor unit with two built-in motors, and all-wheel drive powered by a combination of the two.The system can automatically select the most efficient drive method for the driver's needs and the road conditions.The two motors built into the twin motor unit are individually controlled and torque vectoring is used to create a torque difference between the left and right tires, improving the turning performance.The electric drive system was developed with consideration for layout feasibility and quietness.The two motors built into the twin motor unit and the inverter that drives the motors have been newly developed.By installing this system in the 2015 model year RLX, we achieved engine performance equivalent to a car with a V8 engine at 0-60 mph in 5.4sec and fuel economy equivalent to a car with an L4 engine at 30 mpg.
