21. Bahrain Grand Prix - 2014
The 2014 Bahrain Grand Prix will be long remembered as probably the pinnacle of the many on-track battles between fractious Mercedes team mates Lewis Hamilton and Nico Rosberg.
The pair dominated qualifying, but Hamilton beat polesitter Rosberg off the line to pull out a big lead only for it to be swept away by a late safety car. Despite orders from the pit wall to bring the cars home safely for a Mercedes 1-2, Rosberg threw everything at his team mate when the race resumed with ten laps to go.
In the end, Hamilton emerged victorious and went on to win that year's championship, his first with the Silver Arrows squad. Rosberg wouldn't win the title until 2016, and - exhausted by the effort required to finally beat Hamilton - he promptly retired five days later.
