Let's be realistic about that. I think Mercedes when it started the engine [development] didn't have a budget. It spent. And then lots of teams don't and can't. I mean Red Bull, for example, that won four world championships, didn't know the word "budget", and it's a case that it hadn't got the ability to have the engine that it should have had. Because somebody else [Mercedes] had the engine, wouldn't let them have it, because they didn't want competition.

Bernie [Ecclestone] is the commercial rights holder so the more outgoing the champion is, the better. Of course. I also do think about our sport and want to make an effort - but in my own way. I am Nico [Rosberg] and not Lewis [Hamilton]!

But when it comes to F1 I am a huge Lewis [Hamilton] fan because he is a super promoter of the sport. From a pure business aspect - sorry Nico if I have to say this - you are not so good for my business.

A wise man who was always helpful to me: Mr (Enzo) Ferrari. He always supported me.

I suppose it's knowing when you've come up with an idea that works, when you've got it right, whatever it is.

Before they go to the race, people want to think four or five guys could win, but now... Normally you'd say, "One of those two, and I think it's going to be Lewis [Hamiltom]," because that's what had been proved up to now - thank God that Nico [Rosberg] has won some races.

I always thought that dads in the old days where rather macho types who wouldn't get close to a baby, let alone change nappies.
