The 2020 Porsche 911 Carrera S delivers 18 mpg in mixed real-world driving and 33 mpg on highways. These numbers come from Car and Driver tests. They beat EPA ratings of 17 mpg city and 25 mpg highway.
EPA tests happen in labs. They set standards for window stickers. Real drives differ. The Carrera S with PDK automatic matches EPA numbers close. Manual models do the same. Highway tests hit 33 mpg at 75 mph. This beats other 911 models by 2 to 3 mpg.
Owners see good results. A Carrera 4S driver hit 20 mpg combined. Steady driving gives 22 mpg. Hard acceleration drops to 15 mpg. These match the 992 generation design. In mixed conditions over long trips, drivers average 28 mpg.
Your MPG depends on factors like traffic and trips. City traffic lowers scores. Long highway runs raise them. Use premium 99 octane fuel like Shell V-Power for best results. Light throttle and steady speeds boost MPG. The 3.0-liter twin-turbo flat-six makes 443 hp. It runs best below 1,800 RPM at 75 mph.
Light weight of 3,298 lbs helps fuel economy. Strong aerodynamics aid it too. Mild weather keeps numbers near tests. Cold starts or hills lower them.
