German carmaker Porsche has revealed the all-new 911 GT4 R, making it the first GT4 customer race car based on the iconic 911 instead of the 718 Cayman. The new race machine will make its competition debut during the 2027 motorsport season and will be sold to customer racing teams across the world.

Porsche says the new model brings more power, a wider track and improved race technology while continuing alongside the Cayman GT4 RS Clubsport in its customer motorsport range.
