Ferrari's Sebastian Vettel is the 2015 Race of Champions Champion of Champions after securing victory against nine-times Le Mans 24 Hours winner Tom Kristensen.
This is the German's first overall victory, despite having won the Nations Cup six times, though he and team-mate Nico Hulkenberg lost out to Team England on Friday evening at London's former Olympic Stadium.
Saturday was however Vettel's day, needing just two races out of three to secure his title as Champion of Champions.
The four-time Formula 1 champion beat Kristensen in both the Radical SR3 SRX and KTM XBow cars. The Dane made a crucial error in the second heat, hitting the barrier and handing Vettel an easy victory.
"To be honest, I've tried so many times so today was a surprise," said Vettel.
"We all know with this format you don't get much time in the car so you need to be quick when it matters and find the rhythm .
"I was able to find it today and end up in the the fine. In the first race, I pushed very hard.
"I think Tom had a bit of a problem in the second run in the final, so not entirely straightforward, but very happy and honoured to win."
Vettel's route to the final included beating Hulkenberg, World Rallycross champion Petter Solberg and defending Race Of Champions winner David Coulthard.
Meanwhile Kristensen dispatched Formula E champion Nelson Piquet Jr, British Touring Car Championship legend Jason Plato and Blancpain Endurance champion Alex Buncombe.
