Infiniti has unveiled a working prototype of the Project Black S concept coupe, which was first shown at the Geneva Motor Show two thousand seventeen. The modified version of the model was brought to the auto show in Paris 2018.
The Infiniti Project Black S is built in conjunction with the Renault Sport Formula One Team to demonstrate how hybrid technology for Formula 1 can be used in a conventional road car.
The design of the coupe uses a lot of solutions borrowed from the Renault racing team. For example, the two-door received massive air intakes and a ventilated hood, which is designed to provide more efficient cooling of the technical filling. Plus, the concept boasts a massive rear wing.
The project is based on the Infiniti Q60 Red Sport 400, which is powered by a 3.0-liter V6 twin-turbo engine that develops 405 hp. and 475 Nm. At the same time, the prototype additionally received three electric motor-generators and a lithium-ion battery with a capacity of 4.4 kWh.
Such a superstructure is used here as an energy-saving system that generates electricity during acceleration and deceleration. The first two electric motors store energy during acceleration, while the rear MGU-K stores energy during deceleration.
The performance of the latter is 163 hp, while it is connected to work only during acceleration, actively helping the gasoline engine and spending the stored energy. As a result, the total power plant of the concept reaches 568 “horses”.
Unfortunately, while Infiniti chose not to disclose the dynamic characteristics of the rear-wheel drive prototype Project Black S Concept, however, it definitely takes less than 4.0 seconds to accelerate from zero to a hundred.
The installation of additional electric motors added about 200 kg to the weight of the original Q60 Red Sport 400, so during the development of the project, the company specialists replaced most of the coupe body panels with carbon counterparts. The hood, roof and fenders are made of carbon fiber here, while the car has lost the rear sofa and hatch.
As a result, the engineers managed to lighten the structure up to 1,775 kg, which is 24 kg lighter than the donor, and the center of gravity turned out to be slightly lower, which contributes to improved handling. The latter is positively influenced by a sports suspension and three control electronics modes, which change the operation of electric motors.
Among other things, there are powerful carbon-ceramic brakes with 380mm discs at the front and 360mm at the rear. The two-door is also equipped with a sports suspension and has three driving modes (Road, Quali and Race) that change the way the electric motors work.
In August two thousand nineteen, the Japanese reported that work on the Infitini Project Black S was completely completed (everything took 2.5 years), while the decision on the possibility of a small-scale production of the model should be accepted by the end of the year.
