Infiniti brought along the irrepressible Q50 Eau Rouge to the Goodwood Festival of Speed last week, and has released this footage of the 568-hp sedan tackling Lord March's legendary hillclimb. Piloted by Sebastian Buemi, the prototype – powered by the GT-R's 3.8-liter twin-turbo V8 – made rapid progress of the ascent. Unfortunately the car's awesome exhaust note can't be heard over the unrelenting techno music.

Infiniti has yet to green light a production variant, but if it does make it to market, expect the Q50 Eau Rouge to be rolled out in low volumes and for a limited time only.
