Ask Latvala to slow down to Mikkelsen pace and he will be magically more consistent. Ask Mikkelsen to increase pace and to try to match Ogier's in every rally and Mikkelsen will become inconsistent. The thing is, neither of them wants probably change their driving, because Latvala is dreaming to be World Champion and Mikkelsen is comfortable with his 1 min behind to Ogier at the end of any rally.
Also, consistency comes with experience so please don't compare relatively inexperienced drivers like Tanak and Kubica to drivers like Hirvonen and Sordo who have over 10 years of WRC experience, because it just doesn't prove anything.
I'm really looking forward to next season to see what Hayden and Thierry will do. The new i20 won't be slower for sure, so it could be interesting to see how the fight inside the team will help Hyundai start delivering.
