More than 51,000 spectators watch Swedish all-rounder Mattias Ekström clinch a surprise win against Sébastien Loeb to take this year's Champion of Champions crown.

On his way to claiming the 2006 title, Ekström's other victims included Finland's Heikki Kovalainen and Sébastien Bourdais, while Loeb reached the Super-Final after defeating former World Rally Champ Colin McRae in the Rally Drivers' final.

After three years at the Stade de France in Paris, The Race of Champions – Nations Cup to switch to the new Wembley Stadium in London for 2007.

Mattias Ekström silenced the Parisian crowd at the Stade de France this evening with a surprise win over home star Sébastien Loeb to claim victory in The 2006 Race of Champions.

It took the Swede just two races in the best-of-three Super-Final shootout to see off the three-time World Rally Champion. He also twisted the knife in the wound by defeating the Frenchman in the opening race which saw them compete in identical Citroën Xsara WRCs, the car that has taken Loeb to three straight world rally crowns.

"I'm absolutely thrilled to have won The Race of Champions," said the euphoric Swede. "It's the best moment in my life. Better even than winning my DTM title in 2004. And I'm especially proud to have beaten Loeb in his own car. I knew before that race that it would be tough and I just told myself to go for it. I didn't get off to a very good start but then the adrenalin kicked in and I fought back. Unbelievable."

On his arrival at the Stade de France this morning, the Swedish all-rounder, who has competed in this year's DTM as well as in two rounds of the World Rally Championship, was in fact feeling sick. "When I woke up this morning I had a bad stomach and I've eaten nothing all day," he revealed. "But I really wanted to get a good result and I definitely didn't like being knocked out of the ROC-Nations Cup with Tom Kristensen so early on. This is the type of circuit where if you make just one mistake it's finished. And if you only give it 99% you are beaten. To beat Seb in his own car you need to be absolutely spot on."

Defeated finalist Sébastien Loeb, who was making his return to the competitive arena today after sustaining an arm injury while mountain biking last September, was swift to praise Ekström for his performance. "Mattias is quick on a rally stage and also quick on a race circuit. And on top of that he drove very well today. He deserves to be champion. I was especially impressed by his speed in the Xsara WRC. It was close run, but he then left me standing in our race with the Renault Mégane Trophy."

Ekström began the competition by beating his fellow DTM runner – and reigning champion – Bernd Schneider before dispensing with Heikki Kovalainen by a mere 2/1000ths of a second in the Drivers Group semi-final. "I think he was the toughest one to beat," he said. "That was tough and he has more experience with the Mégane. At the end of the race I didn't know who had won."

The last 'racer' in his path on his way to the super-final was another Frenchman, Sébastien Bourdais. "I was a bit behind in my race against Ekström," admitted the 2006 Champ Car Champion, "so I started to push and then I locked my front wheels. I knew at once that I was in trouble and I hit the tyre wall."

Meanwhile, Loeb progressively picked off Spaniard Nani Roma, ROC-Nations Cup hero Travis Pastrana and finally Colin McRae. "I did a good job," reported the Scot, "but to beat Seb Loeb in a Citroen is never easy. I could only give it my best shot."

IMP President and The Race of Champions organiser Fredrik Johnsson profited from the end-of-event festivities to announce a new venue for The Race of Champions – Nations Cup in 2007: "I want to say a huge thank you to everyone at the Stade de France and the fantastic French fans for the three great years we have had here. For 2007, we have been talking to some of the world's most prestigious stadiums and I can tell you this evening that the 20th anniversary event will take place next year at the new Wembley Stadium in London, England. But we do hope to be able to come back here to Paris again some time in the future."

What the drivers said...

Sébastien Bourdais (defeated in Race Drivers' semi-final by Ekstrom, Renault)

"I was a bit behind in my race against Ekstrom, so I started to push and then I locked my front wheels. I knew at once that I was in trouble and I hit the tyre wall. I tried to continue but the oil temperature warning came on and I slowed. I've had a great day: I won some races and I wasn't kicked out of first round in either competition. So that's good. We've had difficult conditions for driving today but I've had a good time."

David Coulthard (defeated by Muller in Race Drivers' 'eighth'-final, Aston Martin)

"I've had great fun and a great weekend… as usual. I hope I'm invited back. I missed a change to 2nd gear early in my race."

Marcus Grönholm (defeated by McRae in Rally Drivers' quarter-final, Porsche)
