Earlier quoted context omitted.
> Mercedes win, not because they also produce the engine, but because they pour nearly half a billion euros into the car It takes more than just throwing money at the problem to win. Otherwise, Red Bull (paying for two teams in full) and Ferrari would be doing a lot better right now.
Mercedes, excluding the engine development, outspend both of those teams. All three outspend the rest of the field by quite some margin.
Ferrari's last driver's championship win was 2007, and last constructors championship win was 2008. If simply outspending their competitors by 5% would make all the difference, I think they would have tried it by now (and infact, if you look at previous years, they have, and failed)
