The Infiniti Q50 Eau Rouge prototype roared its engine at the 2014 Goodwood Festival of Speed in West Sussex, England.

Making its first ever active appearance in public, the vehicle was driven by Sebastien Buemi and Infiniti Red Bull team principal Christian Horner with the presence of about 50,000 car fanatics.

The Infiniti Q50 Eau Rouge prototype is powered by a twin-turbo 3.8-liter V6 engine that delivers 568 PS, and engine similarly found in the Nissan GT-R.

"The Festival of Speed attracts some of the world's most passionate enthusiasts – exactly our sort of people in other words. To be able to share this event with them, and introduce for the first time in Europe the Q50 Eau Rouge running prototype, was therefore brilliant – but even better to get such a positive reaction from everyone," said Infiniti Europe Vice President Francois Goupil de Bouillé.

Infiniti has still not confirmed plans for a production version of the Q50 Eau Rouge. However, Infiniti President Johan de Nysschen said that the car could be relatively low volume and only have a two-year life cycle. He also mentioned that the vehicle could cost USD 100,000 (around PHP 4.4 million).
