By 1977, Porsche gained more experience in turbocharged engines so the German carmaker brought a new version of the 911 Turbo.
It was more powerful and handled better.

The 1977 Turbo was the new flagship. It came improved in all the areas to give more confidence to its customers. The 1975 model was considered too brutal and hard to handle, so the 1977 version came to fix most of those problems. The most noticeable difference was the 0-100 kph (0-60 mph) time, which was improved by 0.2 seconds.

The look was slightly different between the 1975 and the 1977 model. The 1977 model featured the same wide rear fenders with black guard film applied in front of the rear wheel-arches. The rear wing with the black hard rubber was much bigger. Underneath, in the engine compartment, there was a big intercooler.

Inside, the Turbo was fitted with all the bells and whistles available in the Porsche store, with leather interior and bucket seats in the front and leather seats in the back. The instrument cluster was the same as in the Carrera and there was no turbo-gauge. It didn’t feature air-conditioning though, just a ventilation system.

The engine was a 3.3-liter flat-six with one big turbocharger that offered 300 hp. It was mated to a 4-speed manual. The regular 5-speed manual from the Carrera couldn’t stand the 430 Nm (317 lb-ft) of torque.
