2018 Porsche 911
22 mpg city / 30 mpg hwy / 25 mpg combined
Since its initial introduction in 1963, the Porsche 911 has become one of the most iconic sports car on the planet. Although the 911 Turbo has topped the 911 lineup since the 1970s, all 911 Carrera models are now powered by turbocharged engines; the only exception is the normally-aspirated limited edition 911 GT3. The standard engine for the 911 Carrera is a twin-turbo 3.0-liter horizontally-opposed 6-cylinder unit producing 370 horsepower and 331 lb-ft of torque, rated at 30 mpg highway. At the top of the Carrera range is the Carrera GTS, powered by a 450-horsepower 3.0-liter engine rated at 26 mpg highway. The 911 Turbo S derives power from a twin-turbo 3.8-liter 6-cylinder producing 580 horsepower and 553 lb-ft of torque, but still manages 24 mpg highway.
