Introduced as a concept in Detroit and with the GT-R's 560-hp twin-turbo V6 in Geneva, the Q50 Eau Rouge "is now an official project" according to Infiniti boss Johan de Nysschen. That means the firm has green lit an official engineering feasibility project. At least one production prototype will now be built to explore how to fit an engine designed for a 4WD transaxle-equipped sports coupe into a four-door sedan with a standard-sited transmission.

Speaking with Autocar, de Nysschen said: "There are many things to look at, details like the different vibration harmonics that result when you take an engine designed for one application and fit it in another. This is quite a complex process." Given its previous exploits, we have no doubt the carmaker will solve all issues with the GT-R powered Infiniti Q50 Eau Rouge and look forward to seeing it in action.
