Nico Rosberg has revealed that Lewis Hamilton has not called to congratulate him on his maiden Extreme E victory. The two F1 greats have both entered teams into the inaugural off-road event, reigniting their rivalry that frequently spilled over throughout the early 2010s.
Between 2013 and 2016, the pair were Mercedes teammates, leading to some memorable clashes and battles on track.
Both are now setting their sights on taking home silverware as Extreme E team owners, although it seems as if they still aren't on speaking terms just yet.
"No, but he probably would if he had my number," Rosberg told German outlet Sport 1 when asked if Hamilton had called him after the Extreme E race.
"Still, how cool is that we are now competing against each other as team bosses and are also first and second in the championship? It’s funny that the duel now continues here."
After Hamilton had won the F1 world championship in 2014 and 2015, Rosberg finally got the better of his old friend in 2016 - retiring in the immediate aftermath.
Since then, he has gone on to champion several sustainable projects, with Extreme E being one of the German's most significant endeavors. Rosberg Xtreme Racing Team won the opening race of the season in Saudi Arabia, while Hamilton's X44 came in third.
"Our teams were in duels all weekend. Sometimes his team was first, sometimes mine. It was a really big duel and in the end we were able to swing it our way, which made me very happy," Rosberg concluded.
