For the 1976 model year, Porsche introduced the Porsche Carrera 3.0 with wide rear flares, optional whaletail, and a variety of other luxury options. It was available in all markets except North America. The Carrera 3.0 was fitted with a variation of the 930 Turbo’s 2994 cc engine (minus the turbocharger). The engine (dubbed the 930/02) featured K-Jetronic CIS. It developed 200 PS (150 kW; 200 hp) in contrast to the older Carrera 2.7 MFI model’s 210 PS (150 kW; 210 hp). The crankcase and gearbox housing were made of aluminium rather than magnesium for improved reliability.
Magnesium cases were renown for thermal expansion/contraction issues as engines grew in displacement and heat generation also increased.
The new engine, which featured bigger intake and exhaust valves, produced greater torque allowing the Carrera 3.0 to achieve the same performance as the previous Carrera 2.7, 0–100 km/h in 6.1 seconds and 0–200 km/h in 27 seconds. Both versions boasted a top speed of approximately 236 km/h.
The 911 Carrera 3.0 was produced in both targa (1,125 examples produced) and coupé (2,566) versions. The Carrera 3.0 was available with manual gearbox (type 915) with 4 or 5 speeds as well as 3-speed automatic transmission (called the Sportomatic). Production totals were 3,691 manual cars and 58 Sportomatic cars.
