Toyota Auris HSD (2011) Hybrid Synergy Drive

Toyota Auris HSD (2011) Hybrid Synergy DriveToyota Auris HSD (2011) Hybrid Synergy Drive is a full hybrid capable of operating in petrol and electric modes alone, or a combination of both. Its Hybrid Synergy Drive system delivers the energy-saving qualities of a series hybrid, combined with the performance benefits of a parallel hybrid. The technology delivers impressive, seamless acceleration and remarkably quiet running, with class-leading fuel consumption and CO2 emissions from 74.3mpg and 89g/km. Toyota's latest generation Hybrid Synergy Driver uses a 1.8-litre VVT-i petrol engine, a powerful electro motor, generator, high performance battery and a power control unit. A power split device with a planetary gear system combines and reallocated power from the engine, electric motor and generator according to the car's operational requirements. The key to the successful installation of the system in Toyota Auris's front-engine platform is the fact the electric motor, generator and power split device are housed in a single transmission casing that is the size of a conventional gearbox. The seamless E-CVT electric continuously variable transmission is controlled by shift-by-wire technology via an electric shift lever. The lightweight and compact four-cylinder, 1,798cc Atkinson Cycle VVT-i engine develops 97bhp at 5,200rpm and 142Nm of torque at 4,000rpm. The high performance permanent magnet synchronous 60kW electric motor generates a maximum 207Nm between zero and 13,000rpm.
