Lewis Hamilton admits he still doesnt know why his and Nico Rosbergs mechanics were swapped by Mercedes but is convinced success is around the corner with his new crew. The world champion has slipped 43 points behind his team-mate having been blighted by engine failures in 2016 with some social media conspiracy theorists linking his problems to a change of mechanics at the start of the season.Hamilton has repeatedly backed his team and, when asked by Sky F1s Martin Brundle why Mercedes decided to mix it up, said: I dont know! I cant answer that for you. I thought there was good chemistry but I have to say Im really happy with how things are now, Ive got a great group of guys. But would he rather have kept a winning team together?When you work with a group of guys so closely you build a bond. Its hard to explain but theyre your soldiers, thats your squad, Hamilton continued.For sure, it was emotional for all of us, those that were really connected in that way. So much success and ups and downs weve had because thats what you experience together.It was difficult in the beginning but now I can experience that with new guys who are just as enthusiastic and just as driven to win. Mercedes will run an improved MGU-H on Hamiltons car at the Spanish GP in a bid to solve reliability problems and while the Englishman accepts it will be tough not to exceed his engine limit this season, he is also fearful of a 10-place grid penalty for reprimands. Vote: The best line-up in F1 Lewis and Nico? Max and Daniel? Fernando and Jenson? Or Seb and Kimi? Hamilton received his second rap of the campaign in Russia, which he labelled ridiculous, and drivers are only allowed three before being punished with a 10-place grid penalty.He added in Barcelona: I think afterwards I was like, if youre going to penalise me, give me a fine and put the money towards a road safety campaign - do something positive at least.But knowing that now I have one more reprimand before a 10-place penalty, its kind of senseless. They could have fined me whatever it is and put that towards a good cause.Watch the Spanish GP live on Sky Sports F1. The race starts at 1pm on Sunday, with build-up underway at 11.30am.
