The following source (http://powrotroberta.blogspot.com/2012/09/bardzo-obszerny-wywiad-z-sami-wiecie-kim.html) which contains a translated interview conducted by omnicorse.it, suggests that during the Ford test Kubica was quicker than Latvala. Considering it was only a test and test times do not necessarily mean much, maybe there isn’t a lot to get excited about, but even though Kubica has had a life’s worth of experience of track racing whereas Latvala hasn’t necessarily, I find this rather exciting. If it’s true, and if we believe that it was Kubica’s first (or one of the first) proper appearance in a racing car since his crash, the guy doesn’t seem to have lost much, if any, pace. As long as he’s physically alright, his head seems to be completely intact.
On a side-note, in the interview he also mentions that before his accident in 2011 he he had reached an agreement with Ford to develop their car on tarmac. He says that ‘larger starts were also under consideration’.
Finally, he voices his hatred of the DRS!
Edit: I don’t know whether this is the website of F1Kate (http://www.f1katewalker.com/1/post/2012/09/kubica-back-racing-at-last.html), but it confirms the story. I also don’t know whether her source would be reliable, but I used to follow her on Twitter during testing and she seemed to provide fantastic insight at the time. @keithcollantine you would probably know whether it’s her?
