Japanese premium automaker Infiniti will unveil a new sporty hybrid concept ahead of the Paris Motor Show next week. The hybrid previews the progress of the company which plans to electrify its product range from 2021.

The Project Black S is based on the Infiniti Q60 coupe, employing what the Japanese automaker calls a Formula One dual-hybrid electrified powertrain. The system is capable of a total output of 563hp, a 40 per cent boost as compared to the Q60’s 400hp from its 3.0-litre V6 twin-turbocharged engine. The company claims the upcoming hybrid concept’s power figures should see it crack the ton under four seconds.

Infiniti is not going to display the Project Black S at the Paris Motor Show. It will instead present it at an off-site unveiling next Monday, ahead of the show’s press days: Tuesday and Wednesday. The concept was teased in a news release last Friday, with the claim that the dual-hybrid system differs from traditional hybrids in the way it recoups waste energy.

Today’s conventional hybrids use regenerative braking to juice up their batteries. The Project Black S does that in addition to recovering heat energy of exhaust gases from the motor’s dual turbochargers. This means it has three motor generator units compared to just one on standard hybrids. Infiniti said it developed the technology through close collaboration with the Renault Sport Formula One Team.

“The Project Black S prototype features a world’s first dual-hybrid powertrain technology and represents the latest development initiative by Infiniti to electrify its cars,” Infiniti said. “This enables the powertrain to generate electrical power under both braking and acceleration.” The sporty hybrid is being unveiled at a time when Infiniti is shifting to electric power for all its models starting in 2021. The company does not offer a hybrid Q60, but makes petrol-electric variants of the Q50 and Q70 sedans as well as the QX60 crossover.

Infiniti spokesman Trevor Hale said, “This project is about exploring the application of high-performance technology from motorsport to homologated vehicles. This experience is invaluable and will contribute to the learnings and experience that go into engineering and producing electric vehicles.”
