German driver Max Wissel will return to Superleague Formula from the Zolder round of the series in mid-July.
Wissel was previously a championship frontrunner in the FC Basel car, which he took to third in the standings in both 2009 and 2010. He will now represent South Korea in a car fielded by the De Villota team.
"I can't wait to get back out on the track again, it feels like a really long time since Navarra last year," he said. "I've been working hard on my strength, stamina and overall fitness and I feel really ready for this.
"I've had some good results in the past and now I think that I'm better prepared as a driver. The level of drivers in the championship is getting higher and higher and I know that I've also improved as a driver. I am looking forward to the higher level of competition."
