PORSCHE WERKFOTO - 1984
Porsche 911 Carrera. More contemporary than ever for its 20th birthday.
At the IAA in Frankfurt in 1963, Porsche presented the 911 for the first time - at that time with a two-liter machine that produced 130 hp.
To celebrate the 20th anniversary of this classic sports car, Porsche is presenting it at the 1983 IAA as a 911 Carrera with a 3.2 liter engine and 231 hp (170 kW).
Compared to the previous model 911 sc, Porsche has achieved an increase in output of 27 hp (20 kW) while simultaneously increasing the maximum torque from 267 Nm to 284 Nm and significantly reducing fuel consumption through extensive design measures on the engine, mixture preparation and ignition.
The extension of the stroke by four to 74.4 millimeters resulted in an increase in the displacement to 3164 cubic centimeters, a reduction in the combustion chamber near the spark plug, and the optimal performance increase in the compression ratio to 10.3:1. Ignition and injection are controlled by a Bosch Motronic, which, unlike previous systems, directly uses the cylinder head temperature as a measure of the operating temperature in the 911 Carrera. In addition to the overrun fuel cut-off, the Motronic in the 91l Carrera also controls the function of the idle speed control and an active anti-jerk function, which guarantees smooth emergency operation even with the most economical mixture control.
The five-speed transmission of the 911 Carrera has a new gear ratio that is tailored to the changed engine characteristics. An external transmission oil cooler reduces possible wear despite the higher engine power. Porsche has also adapted the car's braking system to the noticeably improved driving performance made possible by the new Carrera engine. A further reduction in the tendency to fading due to cooling was achieved by using brake discs 3.5 millimeters wider with larger ventilation openings. Larger brake pistons on the rear wheels and the brake force regulator adopted from the 928 S serve to improve the brake force distribution, which counteracts the tendency of the front wheels to lock up when it is wet. A brake pad wear indicator in the cockpit warns the driver about 700 kilometers in advance that the pads are nearing their end. The new 911 can also be recognized by the fog lights integrated in the front apron, new cast aluminum rims and the "Carrera" lettering on the rear. The new optional extras for the 911 Carrera include a new rear spoiler, which, in conjunction with the front spoiler, contributes significantly to improving driving stability at high speeds. The coupe version of the Carrera int can also be supplied in a turbo look on request. This additional equipment also includes the chassis of the 911 Turbo and its rear spoiler.
In addition to new interior fittings for all 911 Carrera versions, additional convertible top colors are also planned for the Cabriolet: in addition to coulters, now also blue or brown. In addition, a large tarpaulin in the respective top color can be delivered for the convertible.
