Porsche 911 GT3 RS Walter Rohrl onboard

We've had Porsche's 911 GT3 RS through the MOTOR office this week.

There will be a full feature in an upcoming issue and video as well, but in the meantime who better to give you a taste of its ultimate abilities than two-time world rally champion Walter Rohrl?

The venue is the fiendishly difficult Bilster Berg driving resort in Germany, designed by F1 circuit architect Hermann Tilke, supposedly with input from Rohrl himself.

Over dinner at the recent 718 Boxster launch, Rohrl revealed he had been keen to reunite with long-time co-driver Christian Geistdorfer in a GT3 RS for an attack on this year's 25th Anniversary running of Targa Tasmania, but sadly the project never really gained momentum.

As mentioned, you'll be able to read all about it in a future issue, but suffice to say it's a pretty special car, with an engine that deserves to be regarded as one of the greatest naturally-aspirated units of all time.
