We sat up and took notice of the Lexus LF-CC concept when sifting through the pre-Paris show news, not only because it’s a preview of the next-gen Lexus IS, but because it’s a looker, following the footsteps of the much-praised LF-LC hybrid 2+2 sports coupe concept from Detroit 2012.

The LF-CC is a mid-sized, rear-wheel drive hybrid coupe concept. It’s more compact than the LF-LC, but integrates various L-finesse design cues from that red hot Lexus. Toyota’s luxury brand describes it as a first illustration of how concept cars are truly influencing future models. Ignore the showcar detailing and there’s a production IS Coupe there.

They’re using the same language for what’s under the hood, calling it a new Lexus powertrain for future production, so be in no doubt that this is more than just a flight of fancy. It combines a 2.5 litre four-cylinder petrol engine with a compact, high-output, water-cooled permanent magnet electric motor.

The DOHC engine runs on the Atkinson cycle and has D-4S direct injection. CO2 emissions target is below 100 g/km and the powertrain will achieve class-leading energy efficiency, with more than 2 hp produced per gram of CO2, says Lexus.

We get a first look at the LF-CC’s cabin, which wasn’t shown before the Paris debut. Lexus has also released pics of a dark-coloured LF-CC to go along with the original ‘Fluid Titanium’ exterior hue. Gallery and another video (featuring the designers) of the LF-CC concept are after the jump.
