1970 led the Volkswagen and Porsche for the distribution of the sales company founded 914 in Ludwigsburg to develop a successor model. The sports car should be produced cost from as many large-scale parts of the VW / Audi program. The aim was to take the new car to the official sales program from Audi.
With a budget of DM 150 million Porsche designed under the name EA 425 a new vehicle. Before the work was completed, in 1975 the new VW CEO Toni Schmücker stopped the development project. Because Volkswagen was at this time by the oil crisis of 1973/74 in economic difficulties. Schmücker not decided the future sports car for Audi that are essential to the introduced in 1974, VW Scirocco is a sports car in the model range of the VW Group was already included.
Porsche bought mid-1975 returned the rights to the design to market the car on its own. Previously agreed Porsche with Volkswagen to move the production of the car in the soon to be closing Audi / NSU factory in Neckarsulm. In return, Porsche was awarded the VW parts for the sports car on favorable terms. This decision was profitable for both parties: Volkswagen was able to run a site, Porsche did avoid the expansion of its production, as the own production capacity should be fully utilized by the planned Porsche 928.
Designed by Harm Lagaay design of the 924 was fundamentally different from the previous Porsche models 356, 911 and 914 Because of the front -mounted engine, had the 924er for a Porsche completely new lines.
The engine was in a long, forward steeply sloping front with pop-up headlights, which opened only when the low beam or high beam. When switched off the headlights were not visible and formed with the hood a smooth surface. The front bumper with spoiler contained the turn signals and driving lights. Due to the smooth surfaces of the body to a low drag coefficient of 0.34 was reached.
The vehicle was a 2 2- seater coupe and had typical two doors. The rear trough-shaped seats were separated by a high drive tunnel and suitable only for relatively small people. Despite many changes in the interior switches and door handles revealed the close relationship to the original Volkswagen design. A Porsche works spokesman said in 1975: "We have, especially on the equipment, a lot of changes - as VW the car would have been poor. "
The vehicle had up to 370 liters a sports car for large trunk, which was below the strongly curved rear window, which was the boot lid simultaneously.
The Porsche 924 took up various style elements of other vehicles. The rear window had similarity with that of the Jensen Interceptor produced since 1966 and the rear side windows were similar to those of the Honda Civic of 1972. Formed the other hand, the 924, the basis for further developments such as the vehicle of the Porsche 944 and the Porsche 968 later
Introduced in the 924 transaxle design was indeed rare at this time, but no novelty in the automotive industry. In 1937, presented Škoda Popular had this drive concept as well as the Lancia Aurelia of 1950 and the Alfa Romeo Alfetta in the year 1972. Through the front placed engine, which was connected by a rigid tube with the rear -positioned gear, resulted in a balanced weight distribution, supported a neutral handling.
As required by the development order, many technical components from the VW group were used in the vehicle. The first built-in water -cooled 2- liter four-cylinder in-line engine with 92 kW ( 125 hp ), it was also in a modified form in the Audi 100 mid-sized cars and the VW LT- utility vehicle. The four-speed manual gearbox and drum brakes on the rear axle also came from the Audi 100 at the front axle wishbone from the VW Golf and the MacPherson strut VW Beetle 1302 were used. The rear wheels were hanging on lateral links from the VW Beetle 1302. In addition, other components from the VW program in 924 were used, for example, the silencer of the Audi 200 Turbo or the coolant expansion tank of the VW K 70 Thus, the production costs were lowered and the base price can be kept low with 23,240 DM 1976. In comparison, a Porsche 911 cost at least 32,000 DM
For the Porsche 924 different paint schemes were offered since its introduction in 1976 over the years. In addition to the extra free serial Unilacken there were metallic finishes, so-called spot colors. For the 924 Turbo two-color finishes were also available, which were made up of different standard and special colors.
The Porsche 924 was established in 1976 as the successor of the 914 marketed below the 911 as " entry level " Porsche. The target group were young families and buyers who are a new 911 could not afford. The former Porsche CEO Ernst Fuhrmann said of the car: "We have once again something for the young people and the ladies. "
Had the first water-cooled Porsche engine four cylinder in line, Bosch K- Jetronic fuel injection and made maximum 92 kW ( 125 hp ) at 5800 rpm. With a curb weight of 1080 kg, the car reached with this engine a significant for the 1970s, top speed of 204 km / h The sports car required 9.6 seconds to accelerate from zero to 100 km / hr. As a standard consumption 7.7 liters of premium gasoline were given. As standard, the vehicles with 165 - HR -14 tires on 5.5J x 14 - four-bolt steel wheels were delivered, which could be exchanged for 6J × 14 four-bolt alloy wheels and 185/70-HR-14-Breitreifen. To improve road handling Porsche offered surcharge front and rear of stabilizers. Was connected with a four-speed manual transmission from Audi's production.
The interior of the 924 was extensively already in the series. The two front sports seats came from the 911 and were as well as the rear seats relative to the seat cheeks with artificial leather and the seat and the backrest with a plaid. The rear seats were folded down to increase the cargo area of the trunk. The trunk was content to hide with a roll out fabric cover. Instead of the standard two-spoke steering wheel a high-order two-spoke leather steering wheel could be ordered. The three-part instrument cluster behind the steering wheel on the left containing the cooling water temperature and fuel gauges, in the middle speed and mileage display including trip odometer and to the right the tachometer. In the center console of the additional instruments for the oil pressure, a quartz clock with analog display and a voltmeter were above installed. Among them were the cigarette lighter and the warning indicator for the brake pad wear and the driver seat belt. Under the control of the ventilation and heating of the DIN slot for a car stereo with a front speaker and two speakers was back. In the dashboard was located on the passenger side of a lockable storage compartment.
Further comfort functions as the rear windscreen wiper and headlight washer system became available as optional equipment. Fog lamps could also be ordered separately as a trailer hitch for an additional charge. Instead of the sunroof available on request as a special feature, there was a raising and removable roof panel made of plastic, with which the car could be converted into a Targa - style version. This, according to Porsche " removable pop-top " fit expanded exactly in the trunk.
1977 Porsche offered for the vehicle next to the gearbox also has a three -speed automatic transmission and comfort-oriented customers could order air conditioning. When installing the air conditioner, the voltmeter was accounted for in the center console in place of which sat the quartz watch, the space was used for the air conditioning control.
A year later received the 924 several improvements. The body was hot-dip galvanized on both sides and Porsche were for soil group six years anti-perforation warranty. Two accumulator and an additional solenoid valve eliminated the initial difficulties of the Bosch K -Jetronic engine is hot. Standard wider rims with the dimensions 6J x 14 and 185/70-HR-14-Breitreifen evaluated on the equipment of the car. Upon request, the 924 was equipped with a sport-tuned ZF five- speed manual transmission. Inside, the seats received a new upholstery fabric with a herringbone pattern.
In 1979, the 924 series has been extended by a more powerful model, the Porsche 924 Turbo. Next year, the four-speed manual transmission accounted for the 924 in favor of a standard five-speed gearbox. The year 1980 brought changes in the interior. The herringbone pattern was replaced by three new fabrics. The buyer had a choice of plaid, pinstripe and Pasha decor. To the 924 similar visually and technically upgrade the turbo, there was a sports package with stabilizers and Koni shock absorbers on the front and rear axle as well as internally ventilated front discs. There were also 6J x 15 four- hole light-alloy cross-spoke wheels from ATS with 205/60-HR-15-Breitreifen and a three-spoke leather steering wheel instead of the two-spoke steering wheel. For optical rounding the 924 were equipped with sports package with the rear spoiler of the turbos. To meet the increased security needs of customers, an alarm system was included in the accessories.
1981 was one of the three-spoke leather steering wheel as standard and the seat upholstery fabric plaid was replaced by the Berber design. In the front fenders, the side indicator lights were now fitted as standard that were previously only available as an extra. The removable roof panel consisted instead of plastic from this year, as the body of sheet steel. The still coming from the Audi 100 at the rear drum brakes were replaced by disc brakes.
Starting in 1982, the marketing of all Porsche 924 models in the U.S. and Canada has been completely adjusted in favor of the Porsche 944. The 924 Turbo was no longer offered worldwide except in Italy.
In the following years 1983 to 1984 the 924 was still a few upgrades such as the standard mounted rear spoiler from the turbo and a synchronized reverse gear. Inside, the so-called Porsche fabric replaced the Berber fabric used previously. The material variants pinstripes and Pasha were still available.
Mid-1985 the production of the Porsche 924 ran out after ten years of production, as the more powerful Porsche 924 S model was provided for the following year.
924 S ( 1986-1988 )
For the model year 1986 sparked the Porsche 924 S to built with more than 130,000 units from 924. This was due to a more stringent emission regulations in the U.S. market, the fulfillment of which would have been possible with the 2- liter engine only with great effort, and secondly, the setting of the motor type at Audi because of the order volumes down by Porsche. Therefore, the Porsche 924 S decreased in the compression of the 2.5 - liter four-cylinder engine from the Porsche 944 to 9.7: 1, as in the U.S. model. In this version of the engine at 5800 rpm gave a power output of 110 kW ( 150 hp). With a weight of 1190 kg, the car reached a top speed of 215 km / h The car needed to accelerate from zero to 100 km / h 8.5 s standard it was there with a five-speed manual transmission, which could be replaced by an optional three- speed automatic transmission. The suspension and braking systems have also been incorporated into the 924 S with a corresponding adjustment from 944.

With the end of production of the 924 S on 1 August 1988 ended the 924 - series.
924 Turbo Type 931 ( 1979-1982 )
Sales of the 924 were good. However, many customers complained about the low for a sports car engine performance. In addition to the 924 adhered to the blemish with a Volkswagen-/Audi-Motor to be a " pure-bred " Porsche. With the introduced in 1979 Porsche 924 Turbo ( factory code 931 ) Porsche responded to the wishes and also wanted to refute the prejudice against the engine.
The engine was still the 2- liter four-cylinder engine from the Porsche 924 developed a new cylinder head with hemispherical combustion chambers and arranged differently spark plugs. Then there was a KKK turbocharger, which generated more than 0.7 bar boost pressure. The engine produced at 5500 rpm, a maximum of 125 kW ( 170 hp ), enabling acceleration from zero to 100 km / h in 7.8 seconds. The top speed was 225 km / h The chassis, suspension and braking systems have been adapted and improved with existing stabilizers, Koni shock absorbers and ventilated brake discs at the front of the engine power.
Visually, the Turbo differed significantly from a standard 924 and underlined the sport character. In front of the car between the headlights four additional air intakes, were introduced. The front apron had left and the right of the license plate more air vents. By an NACA - right opening on the hood of the turbocharger was sufficient air to be supplied.
In order to achieve a better adhesion with the rear axle, the car had a rear spoiler of polyurethane. The series consisted of 185/70-VR-15-Breitreifen tires on 6J x 15 five- hole light-alloy cross-spoke wheels from ATS that could be exchanged for an additional charge against 6J x 16 light-alloy forged wheels with 205/55-VR-16-Reifen.

The base of this sports car made the 924 Turbo with the 2- liter four- cylinder engine. In order to increase the engine power, the engine lighter forged pistons, hardened camshafts and a revised cylinder head received with a 7.5: 1 to 8.5: 1 compression increased.

In this version of the engine 154 kW (210 hp) at 6000 rpm made . The top speed was 240 km / h and to accelerate from zero to 100 km / h the vehicle needed 6.9 seconds.
For engine performance to match a revised gearbox was installed, which could be supplemented by an optional limited slip differential. To save weight, the Porsche developers resorted to the motorsport and gave the car a new, lightweight exhaust system. The Carrera GT had standard front and rear forged 7J × 15 Fuchs rims and 215/60-VR-15-Breitreifen.
