 |
After the overwhelming success of the O, A and B-series 911's with their 2-litre engines, Porsche introduced a 2.2-litre version in September 1969 (for the 1970 model year). Usefully coming at a time when competition from Ferrari, Lamborghini and Maserati was hotting up, the C-series 911's were once again available in either Coupe or Targa body styles. Customers could also choose from engines in three alternative states of tune, the entry level 911 T with 125bhp, the more luxurious 911 E with 155bhp or the flagship 911 S with 180bhp. All 2.2-litre powerplants received Typ 911 designations. |
| The engines were bored out to 84mm (from 80mm), stroke remaining unchanged at 66mm, enough for a displacement of 2195cc. 911 T's got a new Typ 911/03 unit that produced a healthy if not spectacular 125bhp at 5800rpm (15bhp up on its predecessor). Compression was unchanged at 8.6:1 whilst a pair of triple-choke Zenith 40 TIN carbs replaced the expensive Webers previously fitted. T's ordered with the optional Sportomatic transmission received Typ 911/06 engines, those destined for the USA and thus emissions equipped receiving Typ 911/07 and 911/08 units for the manual and Sportomatic respectively. C-series 911 T's did at last get ventilated disc brakes although in order to keep costs down, they were iron rather than the alloy calipers used on pricier versions. The next step up the ladder was the 2.2-litre 911 E, a car now boasting a Typ 911/01 engine with 155bhp at 6200rpm (up from 140bhp). 911/04's were installed for Sportomatic. Right at the top of the tree though was the 180bhp 911 S, this having been 10bhp up on the outgoing 2-litre version and only available with the traditional five-speed manual transmission. Both the E and S were officially sold in the USA without requiring any special compliance modifications, this thanks largely to their mechanical Bosch fuel injection. |

Other significant behind-the-scenes developments were a coating of Tectyl oil-based anti-corrosion fluid for the chassis and suspension mounting points moved slightly further forward to lighten the steering. External changes were few and far between, all variants receiving new door handles with an opening trigger behind the catch, the E and S also getting lightweight aluminium engine covers to replace the steel items employed previously. Some minor switchgear changes were made inside, the most obvious having been the re-positioning of the indicator and windscreen wiper stalks. |
Production of the C-series 911 ceased in August 1970 when it was replaced by the appropriately titled D-series. Throughout its 12-months in production, the following were built: 6544 T Coupe's, 2545 T Targa's, 1971 E Coupe's, 933 E Targa's, 1744 S Coupe's and 729 S Targa's. The introduction of the D-series 911 in September 1970 signalled few changes of any significance. Most important were the measures taken to combat corrosion, these including a zinc coating for exposed underbody areas and a galvanised steel body shell. Otherwise, there were just a couple of detail alterations to the fuel injection system. D-series production ended in August 1971 after 2517 T Coupe's, 3476 T Targa's, 1088 E Coupe's, 935 E Targa's, 1430 S Coupe's and 788 S Targa's had been completed. 911 2.2 Engine Index |
