911

In 1974, Porsche created the Carrera RS 3.0 with mechanical fuel injection. Its price was almost twice that of the 2.7 RS, but it offered a fair amount of racing capability for the money. The chassis was largely similar to that of the 1973 Carrera RSR and the brake system was from the Porsche 917.

The 911E and 911S used mechanical fuel injection in all markets. The 911T was still using a carb, except in the US where it also used MFI, which accounts for the 9 hp power difference between the two.

The 1970 Porsche 911 was so good that the 1971 model year was basically unchanged. In 1971, the D-series replaced the C-series. The D-series featured galvanized under floor areas that were coated with PVC to make the car more resistant to corrosion.

In 1976 Porsche still made the 911 S Targa, the 911 S Coupe and the 911 E with few changes. However, Porsche headlined the mightiest 911 yet, the Turbo Carrera. They advertised it as “The Ultimate Porsche” and so it was.

In 1969 The wheelbase for all 911 and 912 models increased from 87.0 to 89.3 in, this helped the handing of the 911 when drivers would drive at the 911's limit creating more confidence between driver and car.

The C-series 911 was introduced. All engines went from a 2.1L motor to a 2.2L motor. On the chassis, the front-strut upper attachments points were moved 14mm forward, making steering easier for the driver.

The 1975 Porsche 911 Turbo was a 2 door coupe-bodied car with a rear mounted engine supplying power to the rear wheels. It was powered by a dry sump turbocharged engine of 3 liters capacity. It featured single overhead camshaft valve gear, 6 cylinder layout, and 2 valves per cylinder.

The 1967 911 saw its first major change with the introduction of the semi-open "Targa" model, which in addition to a lift-off roof came initially with a soft, folding rear window. Many ended up being replaced with glass windows, therefore the "soft" Targas are quite rare and valuable today.

Also in 1966, the more powerful 911S model was introduced that raised power to 158 hp. Alloy wheels from Fuchs were offered for the first time and shaved 20 lbs from the 911's weight.

The new 2.0 was engineered with overhead camshafts in place of the dated pushrods, and could accomodate future displacement increases all the way up to 3.6 liters, and could even be turbocharged for production and racing purposes.

As Porsche’s fastest road car to that point, the RS 2.7 was best described by Britain’s Autocar as “sensational – even by Porsche standards.”
