Porsche has introduced the 2027 911 GT3 S/C Cabriolet, a high-performance convertible powered by a naturally aspirated 4.0-liter flat-six engine. This new model aims to blend the track-focused character of the GT3 line with an open-top driving experience.
Why it matters
The release reflects a significant turning point as Porsche evaluates moving toward turbocharged powertrains for future GT3 generations. This shift marks the potential end of an era for the naturally aspirated engine that has defined the GT3 identity since 1999.
The vehicle features a 4.0-liter engine capable of reaching a 9,000-rpm redline. It delivers 502 horsepower and 331 lb-ft of torque, carrying on the naturally aspirated legacy of the GT3 nameplate established in 1999.
