Although he rejoined on Sunday under Rally 2, he was now well down and eventually finished in 17th place.
“I have mixed feelings after Rally de Espana. During these three days there were some positives but unfortunately some negatives as well,” Kubica commented after the penultimate round in the 2014 World Rally Championship.
“I think we maintained a good rhythm today. I think the last stage [SS17] was one of the best for me on Tarmac, but still there was a considerable gap to the leaders which is strange.
“I think we have confirmed my theory that our pace on gravel is actually better [than on asphalt]. The Tarmac season has finished now though and there is only Rally GB left to run – which will be completely different!”
M-Sport boss Malcolm Wilson added: “It was an unfortunate and disappointing day for Robert yesterday, but I was very impressed by his drive and determination to continue. He has a never-give-up attitude to everything he does which is very inspiring.
“He came back under Rally 2 regulations today and has gained some more valuable experience for the future.”
