ALL-NEW 2.5 LITRE FULL HYBRID POWERTRAIN
Representing a new Lexus powertrain for future production, the LF-CC is equipped with an all-new, highly efficient, 2.5 litre full hybrid powertrain delivering a combination of the engaging performance appropriate to a sporting, D-segment coupe and low CO2 emissions, targeted below 100 g/km. This powertrain will achieve class-leading energy efficiency, with more than 2 hp produced per gram of CO2.
This Lexus Hybrid Drive powertrain features an all-new, ultra-smooth running, 2.5 litre 4-cylinder petrol engine mated to a compact, high-output, water-cooled permanent magnet electric motor.
In addition to the petrol engine and electric motor, the LF-CC hybrid drive system further comprises a generator, a high-performance battery, a power split device which, via planetary reduction gears, combines and re-allocates power from the engine, electric motor and generator according to operational requirements, and a compact power control unit to govern the high speed interaction of the system components.
Adapted specifically for the hybrid powertrain, the all-new 2.5 litre, DOHC, 4-cylinder petrol engine benefits from several technical improvements. It adopts the Atkinson cycle and D-4S direct injection technology to optimise both the power and fuel-efficiency benefits of Lexus Hybrid Drive.
Lexus will introduce this new hybrid powertrain into its model range in the near future.
