Superleague Formula will feature 12 rounds next year as part of a heavily-expanded schedule.
The 2010 calendar features two rounds in Britain, the season-opener at Silverstone, and a mid-season round on the Brands Hatch Grand Prix circuit.
Belgium will also host two rounds, at Spa-Francorchamps and Zolder, while the series will also venture outside Europe for the first time, with a round at Turkey's Istanbul track.
Superleague CEO Alex Andreu said: "Next year's calendar marks an exciting development in Superleague Formula's history.
"Thanks to the worldwide economic climate, we had to rein in our ambitions for this season, hence just the six rounds.
"It was always our intention to have 12 by year three however which I'm very pleased to say we've achieved. If the racing is half as good as this season, I'm certain we'll be in for a fantastic 2010."
