Audi has released a teaser image showing six upcoming models in celebration of the 25^th anniversary of its RS models.

With Audi not saying what these car shadows could be, we are guessing the first two to be the new RS6 Avant and RS7 Sportback. They are expected to use the familiar 4.0-litre V8 turbocharged engine that will have more than 600bhp.

The next two is a mystery but it does look like it could RS Q3 and RS Q3 Sportback. Expect the compact SUVs to be equipped with a turbocharged 2.5-litre five-cylinder engine that produces more than 400bhp.

Next up is also a wild guess but we are betting it to be the new facelifted RS4 Avant. It will likely be using the same turbocharged 2.9-litre V6 engine that develops 444bhp in the current model.

Finally, the largest shadow is probably the RS Q8, a sister car to the Lamborghini Urus. It remains to be seen on whether it will have the same power output as the Urus but is likely to use the same 4.0-litre V8 turbocharged engine present in the Lamborghini SUV.
