The Porsche 912 is an entry-level sports car that Porsche built from 1965 to 1969. 1975 appeared as a new edition of the Porsche 912 E , which, however, was only intended for the US market.
Development history
The last Porsche 356 Coupés cost between 14,950 (75 PS, 175 km / h) and 23,700 DM (130 PS, 200 km / h), the Porsche 911 (six cylinders, 130 PS, 210 km / h) 21,900 DM. Between September In 1964 and March 1965, 911 and 356 were built in parallel. From April 1965, the Porsche 912 replaced the weaker 1.6-liter 356. This car had a modified four-cylinder engine from the Porsche 356 SC in the rear, which developed 66 kW (90 hp).
The equipment of the 912 was also simpler than that of the 911. Initially, for example, not five, but only three round instruments were offered in the basic configuration - a 912 driver had to do without a clock and the instrument cluster. Last but not least, the 912 was intended to keep Porsche customers for whom the 911 was too expensive. When it was launched, the Porsche 912 cost DM 16,250, - and was therefore DM 5,650, - cheaper than the 911. At 10–12 liters per 100 km, gasoline consumption was also considerably lower than that of the 911. Porsche offered the 912 overall 4 years on. From 1965 to 1969 the 912 received many minor and major improvements. A five-speed gearbox was offered as an option. Up to the 1967 model there were three instruments: station wagon, speedometer, rev counter and, optionally, a clock and outside thermometer - different instrumentation than the 911 - all in green. However, you could order 2 instruments for a surcharge, then the dashboards could not be distinguished at first glance.
The 1967 model got 5 green instruments as standard, whereby the instrument cluster was simply divided into a fuel gauge and a thermometer and a clock was added - in green. From model year 68, the more modern-looking white fittings came, adapted to those of the 911 without chrome. From model year 1967 the Targa version was available with a foldable rear window. The wheelbase was later lengthened to 2268 millimeters, the fenders widened and the interior modernized.
The 912 was produced in coupé and targa body styles until the summer of 1969.
Porsche 912 E.
In the 1976 model year, the Porsche 912 E was offered exclusively on the US market, as production of the VW Porsche 914 had ceased, but the new Porsche 924 was not yet available in America.
The 912 E was based on the 911 G model and thus had some advantages of this model, such as a galvanized body.
The idea for the 912 E had been around at Porsche for some time, but out of consideration for the sales figures of the 911, it was initially not introduced as a “world market vehicle”. It was only when the American market became aware of the lack of an inexpensive model that the 912 E was remembered and so it was still built.
Due to the small number of units (2099 units) and the fact that the vehicle was very often upgraded with a six-cylinder engine from the 911, very few original vehicles still exist today. Surveys showed, for example, that around 240 coupé models with a sunroof still exist worldwide. There was no targa or convertible version of this vehicle.
A derivative of the engine that had also powered the 914 2.0 served as the drive: an air-cooled four-cylinder boxer engine with a displacement of 2.0 liters and gasoline injection. In the 912 E it was a Bosch L-Jetronic instead of the D-Jetronic of the 914. This had previously been used in the 914 in the 1.8-liter engine for the US market. The engine in the 912 E was detoxified, with a 7.6: 1 compression significantly lower than in the 914, tolerated normal gasoline and developed 66 kW (90 hp) at 4900 rpm, other sources even speak of only 86 SAE hp. In contrast to the original 912, the machine was not a Porsche engine, but the Volkswagen Type 4 engine, also known as the "flat engine". Originally developed for the VW Type 4 , other variants of this engine also powered the VW buses and vans of the second and third generation, where they were replaced in 1982 by the so-called "water boxers".
