Porsche 911 Turbo Reliability

At the 1975 Paris Auto Show, Porsche debuted its first 911 Turbo. This version of the 911 was the top of the range and was called the 930 internally. As soon as the 911 Turbo appeared on the scene, its wide track and legendary rear spoiler served as its distinguishing features. 911 Turbo S is 40 horsepower faster than the standard 911 Turbo model in the current generation. They are both available as coupes or convertibles.


Originally, the Porsche 911 Turbo came with a 3.0-liter engine producing 260 horsepower and mated to a four-speed manual transmission. As of 1978, Porsche revised the 911 Turbo with a larger 3.3-liter turbocharged engine that provided 300 hp with a 300 PS rating. Following that, turbocharged versions of every subsequent 911 generation have been available. The Porsche 911 Turbo reaches a top speed of 180mph.


According to the 2020 Reliability Survey of What Car? the 911 Turbo ranks among the least reliable sports cars. The entire Porsche brand finished in joint 22nd place out of 31 brands in the overall manufacturer rankings. 


The National Highway Traffic Safety Administration falls under the Department of Transportation of the federal government. However, the NHTSA hasn’t tested the 911 Turbo yet. We think the 2021 Porsche 911 Turbo is amazing. Few production cars can match its performance. This vehicle is equipped with all the necessary safety features and performs well while driving and maneuvering.
