With a 400 horsepower 3.0-litre biturbo V6 engine under its bonnet, the Infiniti Q60 Red Sport 400 is no weakling. Having driven the smaller Q50 saloon version powered by the same engine, we can tell you that it’s one of the best force-fed six-cylinder mills around. Still, that output is not enough to propel it to the levels of a BMW M4.

This is the situation that Infiniti is seeking to remedy with the Project Black S, first teased and later revealed in a set of photos. With technical input from group brand Renault’s F1 division, the Project Black S concept packs 500 horsepower thanks to a hybridised version of the same engine as the regular coupé. It also benefits from Renault Sport F1’s kinetic energy recovery system that stores energy recovered from braking and exhaust gas heat in a lithium-ion battery pack, and releases it to aid the turbo when acceleration is called upon. “Infiniti is the premium car manufacturer within the Renault-Nissan Alliance, and a technical partner to the Renault Sport Formula One team, so it is natural that we come together to explore the possibility of bringing innovative high-performance hybrid technology to our customers, says Infiniti president Roland Krueger. “Infiniti has constantly led the way in making innovative new powertrain technology available, and we're extremely excited by the potential of Project Black S,” he adds.

While it’s a promising concept, we aren’t getting our hopes up yet, as Infiniti has a history of letting enthusiasts down after promising a lot. The Q50 Eau Rouge, which packed the Nissan GT-R’s powertrain had us drooling for a while, but only to be dropped eventually. We hope the Project Black S does not meet the same fate. We’ll bring you more details as they’re revealed ahead of its public debut at this week’s Geneva Motor Show.
