The Audi RS Q8 has been spotted running road trials again, and this time our spy photographers have found it wearing less camouflage. A milder performance version, the SQ8, has already been spied running cold-weather tests, and the range-topping RS model could well be the German marque’s non-identical twin to the Lamborghini Urus.

Visual cues typical of an Audi RS model appear here; larger air intakes, wider wheel arches and the Audi RS signature oval exhaust outlets feature here on the development vehicle photographed here. Larger wheels are home to what appear to be composite ceramic brakes, fitted with six-piston calipers on the front axle, along with an RS-specific chassis tune.

Under the hood, the Lamborghini’s 4.0 litre biturbo V8 petrol powerplant produces 650 PS and 850 Nm of torque, and the Italian manufacturer has stated before that the engine in the Urus is unique to Lamborghini, despite similarities in displacement and configuration to other engines in the Volkswagen Group, which both it and parent Audi are a part of.

That said, Audi’s own installation of the 4.0 litre biturbo V8s already produce close to 600 hp, so a tweak to close the gap with the Urus’ output figures isn’t too far fetched. Elsewhere in the RS Q8, technologies set to feature could include four-wheel steering, electromechanical active roll stabilisation, variable drive modes and more. A date for its debut has yet to be confirmed, though when it does the Urus will be rather closely positioned to the RS Q8. Room for an Urus Performante of sorts, perhaps?
