Ekstrom to Spa World Rallycross round in title winning Audi S1

Ekstrom ended his full-time rallycross career after finishing second in the South African finale last year, after his EKS Sport team lost its works support from Audi Sport.

The two-time DTM champion's own EKS outfit continues to operate its three 2018 chassis in WRX this year, for Liam Doran and Andreas Bakkerud in Monster Energy's RX Cartel squad, and Kriszstian Szabo under the seperate EKS banner.

But Ekstrom will make his return in an S1 run by a different team, Swedish squad JC Raceteknik.

He will be joined in the team by rallycross debutant Enzo Ide, the Belgian GT driver having suggested for the last year that he would make his WRX debut having bought an S1 from EKS ahead of the 2018 season.

Next month's event - on May 11 - will be WRX's first at the Belgian Grand Prix Formula 1 venue and the third round of the season after the upcoming Barcelona round on April 27.

"Being on the sofa at home watching Abu Dhabi [WRX's season-opener], I started to imagine racing again and going through Eau Rouge at 200km/h sideways," said Ekstrom, who has not competed so far this year.

"It started to become very tempting. I asked Joel [Christoffersson of JC Raceteknik] if he was interested that I could use my old championship-winning car.

"If that wouldn't have been the case I think I wouldn't have done it.

"It will be nice to just to go to do a race for fun and enjoy it, because when you do a sport at factory level you have responsibility and you're obliged to a lot.

"When you go there for the enjoyment, still for the fans and to put on a good show, for sure I will want to win the race no discussion, but it's way different to do a wildcard entry verses a full championship."

The Swede finished runner-up to PSRX Volkswagen driver Johan Kristoffersson in the two terms following his drivers' title, and last drove his 2016 chassis to a podium finish in Cape Town at the end of 2017.

The 40-year old, who will race with the number 40 at Spa, says he isn't concerned about the development of the other cars in the field.

"I really love that car and always did. I will enjoy driving it to the limit like I always did, if that's fast enough then we will go and pick up the trophy, if not then we will just smile," he said.

"For sure the development has gone up a lot over the years. My car was fast in the last race I drove it and also it got a lot of updates, it's not like I parked it at the end of 2017.

"It's got some damper development from KYB, there is an engine update.

"For sure the car has a lot more lap time than when I drove it the last time and I'm looking forward to see where the lap time will be."
