Finally set to take on the RS designation, the new model is sure to keep BMW on its toes with its M6 model.
At this stage it is unknown what lies beneath the bonnet, however rumours suggest it will adopt the twin-turbocharged V10 engine from the RS6 Avant.
In the RS6 at least, this engine produces an enormous 432kW which is sure to draw attention through the brand's quattro all-wheel drive system.
While these spy shots show quad exhaust outlets out the back of the RS5, the production model should instead bare the RS's trademark twin oval pipes.
No word yet on when this new model will be available.
