Gone are the earlier vehicle's tacked on wheel arch extensions, and in their place are new, subtly flared fenders at both ends.
The styling details for the car's grille and lower air intakes are hidden behind a set of temporary panels. At the rear, the new RS5 now sports two large oval exhaust tips, one each on either side of the rear bumper.
Under the bonnet, the new RS5 is rumoured to ditch the outgoing car's 331kW/430Nm 4.2-litre V8 in favour of an enhanced twin-turbo version of the turbo 3.0-litre V6 fitted to the new S4 and S5. The new RS5 is said to have between 335 and 350 kilowatts at its disposal.
Running with a single turbocharger, the S4 and S5 twins are able to extract 260kW of power and 500Nm of torque from the V6 motor.
With the current S4 sedan capable of completing the 0-100km/h dash in 4.7 seconds, the same time as the old RS4 and RS5, expect the new model to boast improved performance figures.
As with all of Audi's performance vehicles, the new RS5 will feature all-wheel drive as standard. With the smaller engine, and greater use of lightweight materials, the new RS5 should be between 50 to 100 kilograms lighter than today's car.
The new RS5 is expected to debut in the first half of 2017, with one possible unveiling date centred around the Geneva motor show in March. If that proves to be the case, the RS5 won't turn up in Australia until deep into 2017, at the earliest.
