Just as the B&B suspected, the Infiniti Q50 Eau Rouge is indeed powered by a twin-turbo V6, and it comes from the Nissan GT-R. With all-wheel drive and a 7-speed gearbox (of an unspecified nature), the Eau Rouge should blast to 60 mph in under 4 seconds. Can’t outshine its big brother, can it?

The Infiniti Q50 Eau Rouge was one of the more underwhelming concepts at NAIAS. Apparently we’ll find out what’s under the hood at the Geneva Auto Show. The video above shows off the concept’s engine sounds, and it has a distinct exhaust note that certainly doesn’t sound like a V8 engine. What’s most striking are the very audible wastegate sounds, confirming that it is a turbocharged engine. In the Baby Boomer era, the V8 rumble was the audible manifestation of speed and horsepower. For the new generation, it’s the wooosh and psshhhtt of turbochargers and blow-off valves.
