Volkswagen boss Jost Capito has called on the FIA and organisers of events to think more carefully about the itineraries.
His comments come in the wake of last weekend's Rally Italia Sardegna, round six in the 2015 World Rally Championship, which featured one of the longest days seen in the WRC since the 2002 Safari Rally in Kenya, with competitors tackling nine stages on the Saturday and a total competitive distance of 212.83 km.
Capito's objection, however, was not with the competitive distance, but rather with the time spent on road sections to the tests - more than double that of the competitive distance on the Saturday (464.87km) - and also with the unsociable times for service.
“The stages are very tough here, one of the most tough rallies – but I see a little bit of a problem in the mentality of some organisers," he complained.
"They seem to say we need to have long days, 18-hour days for endurance. But I don't really see the sense of doing 500 kilometres each day on public roads, that doesn't give anything to the sport, it doesn't give anything to the competition.
“It's just not good for the fans, they get two or three hours between the stages and they get turned off during the day.
“A service at six in the morning doesn't make any sense for the fans [either] and it's the same with the service at midnight.
“It's also not good for the media, we don't get the reports out before midnight and it's difficult to get into the newspapers the next day.
“The organisers and the FIA should think about the schedule.
"If they want to increase the endurance then do it on the stages and the mileage on the stages, not just the road sections,” he underlined.
