The organisers of the Catalunya Rally have announced a mixed-surface opening day and a final day which includes two runs through a 26-mile stage.
The October 22-24 event, which is based in Salou, will start with an opening day comprising two stages which run on gravel and asphalt, and one completely loose surface test.
For the first time in the history of the modern era of the World Rally Championship, the teams are likely to start Friday with a car in gravel specification and finish it in asphalt trim.
The Saturday and Sunday stages are all asphalt. The pre-event shakedown has been moved closer to Salou and altered to reflect the split nature of the event. The 1.8-mile stage is now part-gravel and part-asphalt.
Clerk of the course Aman Barfull said: "We are and we want to continue being an asphalt rally, but we have included a mixed day. This new rally concept benefits the show, both for spectators and for the media. And it follows the guidelines of the FIA, requesting organisers to provide for novelties and to contribute in order to raise the interest in the WRC.
"The rally consists of eight stages run twice in three days, totalling 792 miles, of which 220 are competitive."
