(CNN) Lewis Hamilton just gets better and better.
That’s the view of Mercedes chief Toto Wolff, who has presided over Hamilton and his team’s recent domination of Formula One. The German manufacturer has won 62 of the last 79 races, completing a clean sweep of the Formula One drivers’ and constructors’ world titles since 2014, with Hamilton taking the championship on three occasions in that time. “One of the things that impresses me the most with him is his personal growth,” Wolff told CNN’s The Circuit during testing in Barcelona.”He gets better within the team every year. He has become an integral part. He’s motivating the guys if they need to be motivated, rather than the other way around.”
