The S7 Sportback isn’t even out yet, but even so it seems Audi is in a hurry to test the RS7 judging by the RS-specific oval exhaust tips and the wider wheel arches. The test vehicle was spied in Spain with a lowered sports suspension and fat tires wrapping the black alloy wheels. Underneath the hood was probably the biturbo 4.0-liter V8, complete with approximately 650 hp. A hybrid version is rumored to follow later in the model’s life cycle with about 700 hp.
