First held in 1993, the three-day event is billed by organizers as providing a motoring experience “like 50 years ago”. The race attracted more than 100,000 fans along the route. / VCG Photo

The cars cover about 450 kilometers (280 miles) on each of the two driving days through picturesque Alpine scenery, starting in Gröbming in the Austrian province of Styria. / VCG Photo

All the participants have to observe speed limits and no electronic devices are allowed in this "pure driving" race. Every hundredth difference from the target time is measured with one penalty point. / VCG Photo
