Tristan Gommendy will stay with the Hitech-run FC Porto for the second Superleague Formula season, which commences at Magny-Cours next weekend.
The 30-year-old former Champ Car driver and Macau Formula 3 Grand Prix winner took a victory for the Portuguese champion club at Vallelunga in the inaugural series last winter.
"Everyone at the club was really nice to me last year and I now have a really good relationship with them, so it's a big pleasure to restart with them," Gommendy said. "We had a very difficult beginning to the 2008 season and we struggled to break into the top five. Porto clearly had higher ambitions but it always kept faith in me -- that's why it was great that we won together at Vallelunga and finished second at Jerez.
"I know Porto has been pushing to keep me for this year, so I'm really happy because I believe we can do something great."
Porto will be competing against Portuguese rival Sporting this season after the Lisbon club's decision to join Superleague.
"The arrival of Sporting adds another exciting dimension to this year's championship," said Gommendy. "While it's an additional team we will have to beat, it's great news for the Portuguese fans, especially when we go to Estoril."
