Mercedes driver Lewis Hamilton reflected on the 2018 season after clinching his fifth Formula 1 world title
The 2018 season has been defined by the battle between Hamilton and Sebastian Vettel and their Mercedes and Ferrari teams.
In a year Hamilton admits he often hasn't had the strongest car, he ranks his fifth career championship among his best and hardest. Their teams are still battling for the constructor's championship.
Vettel stormed into 2018 by winning in Australia and Bahrain to put the pressure on Hamilton, who didn't win until the fourth race. Vettel's season came undone with a series of driver and team mistakes. None was bigger than Vettel crashing out of the lead in a rainy German Grand Prix to let Hamilton win.
That Ferrari calamity started a streak of six wins in seven races for Hamilton, who hit his usual second-half stride. Vettel hasn't won since the Belgian Grand Prix in August.
But a Ferrari resurgence of late only worsens the frustration of a championship lost.
Ferrari's Kimi Raikkonen won the U.S. Grand Prix. Vettel might have won if not for a three-spot starting grid penalty for driving too fast under a red flag in practice.
Hamilton was third in Texas and struggled with his car all weekend in Mexico City. A strong start Sunday was followed by a clunky race just to ensure a fourth for the championship.
After the finish, Vettel got out of his car and approached Hamilton to congratulate him.
Ferrari hasn't won the driver's championship since 2007. Vettel won all his championships with Red Bull from 2010-2013. He signed with Ferrari in 2015 with the goal of bringing the championship back to F1's most famous team.
