The Porsche Supercup has extended its long-standing deal to race on the Formula 1 undercard.
A new contract has been signed for the Supercup, which began life on the F1 support package in 1993, to continue at grand prix meetings for another three years up to the end of 2016.
Porsche Motorsport boss Hartmut Kristen said: 'We're delighted to be able to continue offering our partners and fans exciting racing in such an attractive environment like the top league of motorsport."
Next year's nine-event, 10-round Supercup schedule kicks off at the Spanish Grand Prix in May, includes dates at the Monaco, Silverstone and Spa, and climaxes with a double header at the inaugural Russian Grand Prix on the Sochi street circuit.
This year's Porsche Supercup champion Nicki Thiim followed in the footsteps of the likes of Uwe Alzen, Emmanuel Collard, Patrick Huisman, Stephane Ortelli, Richard Westbrook and Rene Rast.
