The Porsche Supercup will remain a Formula 1 support series after agreeing a three-year extension to its current contract.
The deal sees the official Porsche-backed one-make manufacturer series continue to support F1 races at select European events, plus the United States Grand Prix.
"We’re proud to forge ahead with the close and long-established partnership," said Fritz Enzinger, Vice President Porsche Motorsport. "Formula 1 offers an exclusive setting with a unique flair. This fascination and high media importance represent an ideal overall package for our racing series."
Michael Dreiser, Director Porsche Motorsport Sales, added: "In the future, the Porsche Mobil 1 Supercup will focus on eight European rounds of the FIA Formula One World Championship. Porsche’s national one-make cup series will enhance the Formula 1 support programme at many other events around the world, which showcases Porsche in an attractive environment."
The series, which has been part of F1's support programme since 1993, will run through 2022 where it will celebrate its 30th anniversary.
In 2021, Porsche will switch to using its 911 GT3 Cup car, which is set to be unveiled next year and fielded in the Porsche Mobil 1 Supercup and selected Carrera Cups in 2021.
