The concept, which Infiniti says is inspired by Formula One, is based on the Q50 sports saloon and is intended to show a high-performance variant of the car.
Named after the famous corner at the Spa circuit, Infiniti says its concept "blends road car technology with a thoroughbred motorsport vision".
While performance and interior upgrades on the Q50 concept haven't been revealed, Infiniti has added "aerodynamic styling treatments" and design elements developed from its work in Formula One, where the company is partnered with Red Bull Racing.
The firm's design boss Alfonso Albaisa said: "Performance is a key pillar of Infiniti’s DNA and this car expresses a deepened design interpretation of that. The Q50, with an abundance of technologies, provides a great basis for an extreme performance version, embodied in the design of Q50 Eau Rouge".
