Porsche has launched a new race car, the 911 GT4 R, marking the first time the company has based a GT4-specification competition vehicle on its flagship 911 model. The car, priced at $375,000 in the United States, is set to begin competing in the 2027 motorsports season.

The new model replaces the 718 Cayman-based GT4 race cars Porsche has produced since entering the category in 2016. It is built on the technical foundation of the 992.2-generation 911 Cup car and is powered by a 4.0-liter naturally aspirated flat-six engine.
