In the season, Haas joined the grid. The season began in dominant fashion for Nico Rosberg, winning the first 4 Grands Prix. His charge was halted by Max Verstappen, who took his maiden win in Spain in his debut race for Red Bull. After that, the reigning champion Lewis Hamilton decreased the point gap between him and Rosberg to only one point, before taking the championship lead heading into the summer break. Following the break, the 1–2 positioning remained constant until an engine failure for Hamilton in Malaysia left Rosberg in a commanding lead that he would not relinquish in the 5 remaining races. Having won the title by a mere 5 points, Rosberg retired from Formula One at season's end, becoming the first driver since Alain Prost in 1993 to retire after winning the Drivers' Championship. The final team remaining from the 2010 new entries process, Manor Racing, withdrew from the sport following the 2016 season, having lost 10th in the Constructors' Championship to Sauber with one race remaining, leaving the grid at 20 cars as Liberty Media took control of the series in the off-season.
