It doesn't take much for Lewis Hamilton to spit the dummy, and after the Malaysian Grand Prix he did exactly that.
He was having a fantastic weekend, dominating his Mercedes team-mate and world championship rival Nico Rosberg, and he was set to regain the points lead when it all went wrong on lap 41. I know engine failures are not things we see very often these days, but sorry, sometimes they do happen.
These power units are, all told, developing in excess of 900bhp. That from a 1600cc V6 turbo plus the hybrid is something very special, but to do it with the fuel limitations that the current regulations dictate is nigh-on miraculous. The manufacturers should be getting a big pat on the back and not publicly criticised when it goes wrong.
