Lewis Hamilton has retired early in Australian Grand Prix after what appeared to be an engine problem. Lewis Hamilton's start to the new Formula One season lasted just three laps before the championship favourite was forced to retire because of a 'misfiring cylinder'.
From the 32nd pole position of his career ahead of the season-opening Australian Grand Prix, Hamilton was passed on the run down to the first corner at Melbourne's Albert Park by Mercedes team-mate Nico Rosberg and Daniel Ricciardo on his debut for Red Bull.
On the opening lap McLaren's Kevin Magnussen dropped Hamilton to fourth, and it was clear the 29-year-old was struggling with his car. On lap two Hamilton was then informed by race engineer Pete Bonnington to stop the car and save the engine
