Following the drop-dead gorgeous Eau Rouge concept shown at the Detroit Auto Show - and just weeks before its official Geneva debut - Infiniti has just released this video, showcasing the sound of its upcoming Q50 engine. Infiniti CEO Johan de Nysschen already promised a production performance version that would make over 500hp and 600 lb-ft of torque. With those numbers and this phenomenal sound, can this possibly be a Nissan GT-R V-6 stuffed into a four-door sedan?

Listen to this phenomenal sound and tell us what you think!
