The limited edition Ford Focus RS500, which has close to 350bhp, will be launched next week.
The car's existence has been confirmed by a Ford microsite, which shows the RS500 being driven round its Lommel Proving Ground in Belgium.
The car has been created in response to public demand, and the growing market of aftermarket tuners offering tuned cars with up to 400bhp.
The RS500 is expected to remain as practical as the current RS, keeping its rear seats, but it will be differentiated with a more extreme look, including a large rear wing that can be seen at the start of the video.
The Mk2 Ford Focus RS is limited to 8000 models, with 4000 destined for the UK. Logic suggests the RS500 will be limited to 500 examples.
