As part of its plan to electrify its portfolio from 2021 onward, INFINITI revealed a new Project Black S prototype in Paris, showcasing how Formula One® dual-hybrid electric powertrain technology can be deployed in a road car.
Following the 2017 INFINITI Project Black S design study, the new hybrid electric prototype illustrates the brand’s commitment to developing exciting high-performance electrified powertrains, drawing on expertise from across the Renault-Nissan-Mitsubishi alliance.
The Project Black S fuses high-performance dual-hybrid technology with INFINITI’s award-winning VR30 3.0-liter V6 twin-turbo engine. Its unique ‘energy recovery system’ (ERS) contributes to greater power and torque than the engine upon which it is based. The dual-hybrid powertrain prototype generates 420 kW – equivalent to 563 hp or 571 ps, whereas the conventional VR30 engine produces 298 kW (400 hp / 405 ps). The power to weight ratio is estimated to be 235W/kg, achieving 0-100 km acceleration below four seconds.
The ‘Black S’ designation represents the highest level of performance, dynamic capability, effective aerodynamics and intelligent energy management offered by INFINITI. The prototype is based on the Q60 red S sports coupe and has been developed together with the Renault Sport Formula One Team.
The prototype’s powertrain employs three motor generator units (MGU). A single MGU-K (‘K’ stands for ‘kinetic’) unit harvests kinetic energy from braking. Uniquely, the engine’s twin electric turbochargers are fitted with two MGU-H (‘H’ for ‘heat’) units, to harvest heat energy from exhaust gases. This enables the powertrain to generate electrical power under both braking and acceleration.
