Lexus will introduce the LF-CC, a new, mid-sized coupe concept at the 2012 Paris Motor Show. Earlier this year, Lexus unveiled the LF-LC 2+2 sports coupe concept at the 2012 Detroit Motor Show. (Earlier post.)
The more compact, rear-wheel drive, full hybrid LF-CC integrates various design cues from the LF-LC and illustrates the evolution of the design language to be reflected in future Lexus D-Segment vehicles. The LF-LC is powered by a new 2.5 liter full-hybrid powertrain which will be introduced soon in the Lexus model range. The LF-CC also indicates the launch of a premium mid-sized coupe in the D Segment in the near future, Lexus said.
The new 2.5 liter full-hybrid powertrain delivers a combination of performance appropriate to a sporting, D-segment coupe and low CO2 emissions, targeted below 100 g/km. Lexus says that 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 2.5 liter 4-cylinder gasoline engine mated to a compact, high-output, water-cooled permanent magnet electric motor. Adapted specifically for the hybrid powertrain, the all-new 2.5 liter, DOHC, 4-cylinder engine benefits from several technical improvements. It adopts the Atkinson cycle and D-4S direct and port injection technology to optimize both the power and fuel-efficiency benefits of Lexus Hybrid Drive.
In addition to the 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.
