Porsche 911 is going to come with a big update in the next model year. Almost all models are going to come with a new turbocharged power train. which means that Porsche 911 Carrera and Carrera S are both going to lose their inline flat six cylinder engines. Regular Carrera is probably going to receive 2,9 liter turbocharged six cylinder engine that’s going to come with a 400 horsepower and the same number of pound feet of torque output. This is going to be a large improvement for this model since 2014 Porsche 911 Carrera can produce only 350 horsepower.
