The Porsche 924 is a sports car that Porsche AG produced from 1975 to 1988.

Originally designed as the successor to the VW Porsche 914 for Volkswagen , Porsche launched the car as its own entry-level model below the 911 type . The 924 was the first car from Porsche with a water-cooled front engine and the transaxle drive concept and was an expression of a departure from the technical concept of the previously built models with air-cooled rear engines .

In addition to the series vehicles, the Carrera GTP and Carrera GTR vehicle variants were developed specifically for motorsport in 1980 and 1981, which were used in sports car world championship races such as the Le Mans 24-hour race , where they achieved podium places and victories in the class standings.

The 924 was often not seen as a full-fledged Porsche sports car because of its parts from the Volkswagen Group, such as the 2-liter engine. It was only since the 2010s that the model has been gaining increasing recognition as an old and young timer .

General

In 1970 the sales company founded by Volkswagen and Porsche to sell the Porsche 914 in Ludwigsburg initiated the development of a successor model. The sports car should be produced inexpensively with as high a proportion as possible of mass-produced parts from the VW / Audi range. The aim was to include the new car in Audi 's official sales range .

Porsche EA 425

With a budget of around DM 150 million, Porsche designed a new vehicle under the name EA 425. Before the work could be completed, the new VW CEO Toni Schmücker stopped the development project in 1975 . Volkswagen was in financial difficulties at the time, and Schmücker decided not to develop the sports car for Audi. After the 1973/74 oil crisis, he saw little chance for the new model, and with the VW Scirocco , introduced in 1974, a sports car was already offered in the VW Group's range.

In 1975, Porsche bought back the rights to the previous construction in order to complete the car and market it under its own management. It was previously agreed with Volkswagen that production of the car would be relocated to the Audi / NSU plant in Neckarsulm, which is about to close . In return, Porsche received the VW components for the sports car on favorable terms. This decision was profitable for both contractual partners: Volkswagen was able to continue operating its location at a cost-covering level, Porsche saved the expansion of its production facilities, the production capacities of which were fully utilized with the Porsche 928 .

Series production of the 924 started in November 1975.

design

The body of the 924 designed by Harm Lagaay was fundamentally different from that of the previous Porsche models 356 , 911 and 914. Because of the engine installed in the front, the 924 had a completely new line for Porsche. The head of body design at Porsche, Anatole Lapine , later said of the shape: "The car was designed by someone who had dreamed of a Ferrari all his life but never got one."

The engine was in a long, steeply sloping front end with pop-up headlights that opened when the dipped or main beam was switched on. When switched off, the headlights could not be seen and formed a smooth surface with the bonnet. The front bumper with spoiler contained license plates, indicators and high beam headlights. The smooth surfaces of the body made it possible to achieve a low drag coefficient (C _w value) of 0.34.

The vehicle is a 2 + 2-seater and has two doors, as is typical for a Coupé. The rear trough-shaped seats are separated by a high drive tunnel and are only suitable for small people / children.

Despite many changes in the interior, the switches and door handles showed a close relationship to the original Volkswagen design. A Porsche works spokesman said in 1975: "We have changed a lot, especially in terms of equipment - as a VW the car would have been poor."

With a capacity of up to 370 liters, the vehicle has a trunk that is large for sports cars and is located under the strongly curved rear window, which is also the trunk lid.

The Porsche 924 cites various stylistic elements from other vehicles. The rear window is similar to the rear window of the Jensen Interceptor , which has been in production since 1966, and the rear side windows are similar to those of the Honda Civic from 1972. The 924 is the basis for further vehicle developments such as the Porsche 944 and its successor, the Porsche 968 .

technology

The transaxle construction introduced in the 924 was rare at the time, but not a novelty in automotive engineering. This drive concept already existed before the First World War at Csonka , in 1937 in the Škoda Popular and in the two Alfettas from 1937 and 1972 from Alfa Romeo, the Lancia Aurelia from 1950 and the Pontiac Tempest from 1960. Placed in front The motor, which was connected by a rigid tube to the gearbox positioned in the rear behind the axle, resulted in a weight distribution that was advantageously balanced for neutral driving behavior. As required in the development order, many technical components from the VW Group were used in the vehicle. The initially installed water-cooled 2-liter four-cylinder in-line engine with 92 kW (125 PS) was also available in a modified form in the Audi 100 mid-range car and in the VW LT commercial vehicle. The four-speed gearbox and the drum brakes on the rear axle were also taken from the Audi 100. The control arms from the VW Golf and the MacPherson struts from the VW Beetle 1303 were used on the front axle . The rear wheels were suspended from trailing arms from the VW Beetle 1500. In addition, other components from the VW range were used in the 924, for example the front silencer of the Audi 200 Turbo or the cooling water expansion tank of the VW K 70 . This enabled production costs to be reduced and the basic price in 1976 at DM 23,240. In comparison, a Porsche 911 cost at least 32,000 DM.

Exterior paintwork

Various paint finishes have been offered for the Porsche 924 since its introduction in 1976. In addition to the surcharge-free standard uni paints, there were metallic paints, so-called special colors. Two-tone paintwork was also available for the 924 Turbo, which consisted of different standard and special colors.

Model development

924 (1976-1985)

The Porsche 924 was marketed in 1976 as the successor to the 914 below the 911 as an “entry-level” Porsche. The target group were young families and buyers who could not afford a new 911. The then Porsche CEO Ernst Fuhrmann said of the car: "We have something for the young people and women again."

The first water-cooled Porsche engine had four cylinders in line, Bosch K-Jetronic gasoline injection and developed a maximum of 92 kW (125 hp) at 5800 rpm. With a curb weight of 1080 kg, the car with this engine reached a top speed of 204 km / h, which was remarkable for the 1970s. The sports car took around 9.6 seconds to accelerate from zero to 100 km / h. The standard consumption stated was 7.7 liters of premium gasoline. As standard, the vehicles were delivered with 165-HR-14 tires on 5.5J × 14 four-hole steel wheels, which could be exchanged for 6J × 14 four-hole light alloy wheels and 185/70 HR-14 wide tires. To improve roadholding, Porsche offered stabilizers at the front and rear for an additional charge. It was shifted with a four-speed manual transmission from Audi production.

The interior of the 924 was already extensive in the series. The two front sports seats came from the 911 and, like the rear seats, were covered with synthetic leather on the side bolsters and with a checked fabric on the seat surfaces and the backrest. The rear seats were foldable to increase the cargo area of ​​the trunk. The contents of the trunk could be hidden with a roll-out fabric cover. Instead of the standard two-spoke steering wheel, a higher-quality two-spoke leather steering wheel could be ordered. The three-part instrument panel behind the steering wheel contained the coolant temperature and fuel gauge on the left, the speed and mileage display including the trip meter in the middle, and the rev counter on the right. The additional instruments for the oil pressure, a quartz clock with analog display and a voltmeter were installed in the top of the center console . Among them were the cigarette lighter and the warning display for brake pad wear and the driver's seat belt. The DIN installation slot for a stereo car radio with one loudspeaker at the front and two loudspeakers at the rear was under the control for the ventilation and heating . There was a lockable storage compartment in the dashboard on the passenger side.

Further comfort functions such as the rear window wiper and the headlight cleaning system were available as additional equipment. Fog lights and a trailer coupling could also be ordered at an additional cost. Instead of the optional sliding roof, there was a special feature that could be opened and removed from plastic, with which the car could be converted into a Targa- like version. This, according to Porsche, "removable pop-top roof" fitted exactly into the trunk when removed.

In 1977 Porsche offered the vehicle with a manual gearbox or a three-speed automatic, and comfort-oriented customers could order an air conditioning system. When the air conditioning was installed, the voltmeter in the center console was omitted; the quartz clock, which was used for controlling the air conditioning, sat in its place.

A year later, the 924 received several improvements. The body was hot-dip galvanized on both sides and Porsche gave the floor pan a six-year guarantee against rust perforation. Two pressure accumulators and an additional solenoid valve eliminated the starting difficulties of the Bosch K-Jetronic when the engine was warm. On request, the 924 was equipped with a sporty ZF five-speed manual transmission. Inside, the seats were given a new upholstery fabric with a herringbone pattern. In addition, there was now a silencer with an oval tailpipe and a larger water tank.

In 1979 the 924 series was expanded to include a more powerful model, the Porsche 924 Turbo. Standard wider rims with the dimensions 6J × 14 and 185/70-HR-14 wide tires upgraded the equipment of the car. In the next year, the four-speed manual gearbox was eliminated from the 924 in favor of a standard five-speed gearbox. The year 1980 brought changes in the interior. The herringbone pattern has been replaced by three new fabric variants. The buyer could choose between plaid, pinstripe and pasha decor. In order to upgrade the 924 visually and technically similar to the Turbo, there was a sports package with stabilizers and Koni shock absorbers on the front and rear axles as well as internally ventilated brake discs at the front. There were also 6J × 15 four-hole light alloy cross-spoke wheels from ATS with 205/60 HR 15 wide tires and a three-spoke leather steering wheel instead of the two-spoke steering wheel. To round off the look, the 924 with sports package were equipped with the rear spoiler of the turbo. In order to meet the increased security needs of customers, an alarm system was added to the range of accessories. In addition, a contactless transistor ignition and the brake booster of the 924 Turbo were integrated as standard.

In 1981, the three-spoke leather steering wheel was standard and the seat upholstery fabric was replaced by the Berber design. The side indicators, which were previously only offered as an option, were now installed as standard in the front fenders. As of this year, the removable roof section was made of sheet steel, like the body, instead of plastic. The drum brakes from the Audi 100 on the rear axle have been replaced by disc brakes.

As of 1982, the marketing of all Porsche 924 models in the USA and Canada was completely stopped in favor of the Porsche 944. The 924 Turbo was no longer offered anywhere in the world, except in Italy. The transmission received a synchronized reverse gear.

In the following years 1983 to 1984 the 924 received a few upgrades such as B. the standard mounted rear spoiler of the turbo, gas springs on the bonnet and four interior speakers. In the interior, the so-called Porsche fabric replaced the previously used Berber fabric cover. The fabric variants pinstripe and pasha were still available.

Production of the Porsche 924 ended in mid-1985 after ten years of production, as the more powerful Porsche 924 S model was planned for the following year.

924 S (1986-1988)

Rear view of a Porsche 924 S.

In the 1986 model year, the Porsche 924 S replaced the 924, which had more than 130,000 units. The reasons for this were, on the one hand, stricter emissions regulations in the US market, which the 2-liter engine would only have been able to meet with great effort, and on the other hand, the discontinuation of the engine type by Audi due to the declining order quantities by Porsche. Therefore, in the 924 S, Porsche reduced the compression of the 2.5-liter four-cylinder engine from the Porsche 944 to 9.7: 1 as in the US model. In this version, the engine had an output of 110 kW (150 hp) at 5800 rpm. The vehicle mass is 1190 kg, the maximum speed 215 km / h. The car took 8.5 s to accelerate from zero to 100 km / h. It was available with a five-speed manual transmission as standard, which could be replaced by a three-speed automatic transmission if required.

The chassis and the braking system were also taken over from the 944 in the 924 S with appropriate adjustments. The body remained almost unchanged compared to its predecessor, only the new model received new 6J × 15 light alloy wheels in the "telephone dial design" with 195/65 VR 15 wide tires.

The interior was taken over unchanged from the 924. In 1986 the 924 S had a new price of DM 41,950.

In 1988 - shortly before production was discontinued - the output of the 924 S was increased to 118 kW (160 hp) at 5900 rpm. The maximum torque has been increased from 190 to 210 Nm. The interior has been upgraded with a rear seat bench that can be folded down in two. A four-spoke leather steering wheel and the leather sleeve for the gear knob were part of the standard equipment, like many other details.

When production of the 924 S ended on August 1, 1988, the 924 series also ended.

924 Turbo Type 931 (1979–1982)

Sales of the 924 were good. Nevertheless, many customers complained about the low engine power for a sports car. In addition, the flaw of the 924 with a Volkswagen / Audi engine was not a "thoroughbred" Porsche. With the Porsche 924 Turbo (factory code 931) introduced in 1979, Porsche responded to the requests and also wanted to refute the prejudices against the engine.

The engine was still the 2-liter four-cylinder engine from the 924. Porsche developed a new cylinder head with hemispherical combustion chambers and differently arranged spark plugs. There was also a KKK turbocharger that generated a maximum of 0.7 bar boost pressure. The engine developed a maximum of 125 kW (170 hp) at 5500 rpm and enabled acceleration from zero to 100 km / h in 7.8 seconds. The top speed was 225 km / h.

The chassis, the wheel suspension and the brake system have been adapted to the engine output and improved with standard stabilizers, Koni shock absorbers and internally ventilated brake discs on the front axle.

Visually, the Turbo differed significantly from a standard 924 and underlined its sporty character. Four additional air inlets were installed in the front of the car between the headlights. The front apron had further air slots to the left and right of the license plate. Sufficient air could be supplied to the turbocharger through a NACA opening on the right-hand side of the bonnet.

In order to achieve better road grip on the rear axle, the car had a rear spoiler made of polyurethane . The series tires consisted of 185/70-VR-15 wide tires on 6J × 15 five-hole light alloy cross-spoke wheels from ATS, which could be exchanged for 6J × 16 light alloy forged wheels with 205/55 VR 16 tires for a surcharge .

The 924 Turbo could be ordered with a single-color, solid-color or metallic finish or a two-tone finish.

With a three-spoke leather steering wheel and a leather sleeve for the gear knob, the interior was richer than on the 924. The seats and door panels were covered with the plaid decor, later with the pasha decor. The basic price of the 924 Turbo was around DM 40,000.

In 1981, two years after the start of sales, the engine output was increased by 5 kW (7 hp) to 130 kW (177 hp) by increasing the compression from initially 7.5: 1 to 8.5: 1 and improving the engine management. This enabled the car to reach a top speed of 230 km / h.

In June 1982, production of the 924 Turbo ended after four years. With the Porsche 944 introduced in 1981, the model faced stiff competition, which caused its sales figures to decline. Only in Italy, where the turbo with its 2-liter engine was taxed much less and was therefore still attractive, vehicles were sold until 1984.

924 Carrera GT Type 937 (1981)

The prototype of the Porsche 924 Carrera GT (factory code 937) was presented at the 1979 IAA in Frankfurt. It was supposed to underline the performance of the 924 and at the same time give an outlook on the body shape of the planned Porsche 944.

The basis of this sports car was the 924 Turbo with the 2-liter four-cylinder engine. In order to increase the engine output, the engine received lighter forged pistons, hardened camshafts and a revised cylinder head with a compression increased from 7.5: 1 to 8.5: 1. The maximum charge pressure of the KKK turbocharger has been increased to 0.75 bar and an additional charge air cooler has been installed. The engine was controlled by a so-called Hartig ignition , which increased performance and also kept fuel consumption relatively low at around 9.1 l per 100 km. In this version, the engine developed 154 kW (210 hp) at 6000 rpm. The top speed was 240 km / h and it took the vehicle 6.9 seconds to accelerate from zero to 100 km / h.

A revised gearbox was installed to match the engine output, which could be supplemented by a limited- slip differential if required. To save weight, the Porsche developers resorted to motorsport and gave the car a new, lightweight exhaust system. The Carrera GT had forged 7J × 15 Fuchs rims and 215/60 VR 15 wide tires as standard . For a surcharge, larger wheels with the rim dimensions front 7J × 16 with 205/55-VR-16 tires and rear 8J × 16 with 225/50-VR-16 tires could be ordered instead. The brake system with internally ventilated disc brakes was taken from the Porsche 911 Turbo 3.3 .

The body of the car had widened fenders made of glass fiber reinforced plastic (GRP) at the front and rear . While the front fenders were harmoniously integrated into the lines and already had the shape of the 944, the rear fenders were attached. The front apron, the side skirts and the air scoop on the bonnet were also made of GRP in order to keep the vehicle weight low at 1180 kg. The windshield was glued flush with the body to the c _w - value retained from 0.34 despite fender flares.

The interior was largely the same as that of the 924 Turbo and contained a three-spoke leather steering wheel, a leather gear knob and sports seats and door panels covered in black and red pinstripe fabric. Many extras such as B. an alarm system, a car radio, electric windows, electric mirror adjustment, air conditioning, etc. can be selected. The basic price for the sports car was around DM 60,000.

The Porsche 924 Carrera GT was only built in 1981 in an edition of 400 copies, 200 of which were sold in Germany. Since the vehicle did not meet the strict emissions regulations in the USA, it was not allowed to be sold there. With the six prototypes together, there is a total of 406 Carrera GTs built.

The car served as the basis for the development of the racing car models Carrera GTS, GTP and GTR, which were successful in races in the sports car world championship in the early 1980s, such as B. were used in the 24-hour race of Le Mans .

Special models

From 1977 to 1988, Porsche brought out various special models of the 924, which stood out from the standard vehicles with a particularly rich and in some cases unique equipment. Most of the special models were sold worldwide, some were reserved for a specific market.

924 World Championship model (1977)

The limited special model, sometimes also called the 924 Martini-Porsche, was launched on the occasion of the two victories in the sports car world championship, which Porsche achieved in 1976 with the 935 in Group 5 and with the 936 in Group 6. The car was painted in Grand Prix white and had decorative stripes on the side in the colors of the Porsche sponsor Martini at the time. It had 6J × 14 light alloy wheels painted white with 185/70 HR 14 wide tires and stabilizers at the front and rear. It was also equipped with a leather steering wheel, black leatherette interior with light red carpets and also light red inlays in the seat covers. A plaque with the years of the world championships won (1969/1970/1971/1976) was attached to the center console. The car was delivered with a stereo system (two speakers in the back and one in the front) as standard.

The model had a circulation of 1000 pieces for Europe and 2000 pieces for the USA.

924 Limited Edition (1978 - US only)

The special model, sold exclusively in the USA, was painted dolomite gray metallic with a silver-black decorative stripe on the side. It had 6J × 14 alloy wheels with 185/70 HR 14 wide tires and anti-roll bars at the front and rear. The front of the car had partial leather sports seats and rear partial leather seats with black and white velor seat inlays in a paschal design. There was a two-spoke leather steering wheel and a leather sleeve for the gear knob (only with the four-speed manual transmission). In addition, the model was equipped with a stereo system with two loudspeakers in the rear and a loudspeaker in the dashboard, fog lights and, if required, a removable roof section.

924 Sebring 79 (1980 - USA only)

As a reminder of the victory of a Porsche 935 in the 1979 Sebring 12-hour race in the IMSA GT championship, Porsche launched a special model for the US market with Guards Red paint, Sebring 79 lettering on the front fenders and decorative stripes in yellow / red / black / white on the flanks. A large white 924 lettering was glued to the bonnet . The car was delivered with black painted aluminum wheels and wide tires of size 185/70 HR 14 as standard. The interior was black with red and blue tartan inlays on the seats and door panels. Like the 924 Turbo, the car had a four-spoke leather steering wheel and a five-speed gearbox. A three-speed automatic transmission was optionally available instead of the manual transmission. The equipment also included a removable roof section, a stereo system consisting of two loudspeakers in the rear and a loudspeaker in the dashboard, electrically heated and adjustable exterior mirrors and fog lights.

The model had an edition of 1292 pieces.

924 Le Mans (1980)

Porsche 924 Le Mans

This special model was dedicated to the 24 Hours of Le Mans , in which Porsche had five overall victories as well as numerous class victories up to 1979, and to the newly developed 924 Carrera GTP racing car, which was used in Le Mans in 1980.

The vehicle was painted alpine white and had narrow yellow / black / red decorative stripes and white piping all around. Le Mans logos were glued to the front fenders . The car had a rear spoiler removed from the 924 Turbo and a removable roof section available as an option. Standard were 6J × 15 ATS cross-spoke wheels in a turbo look and wide tires in the dimension 205/60 HR 15 as well as stabilizers at the front and rear. Inside, the car has been upgraded with a four-spoke leather steering wheel with a diameter of 36 cm, a leather sleeve for the gear knob and black artificial leather with black / white pinstripe fabric inserts in the seats. 924 lettering was applied to the sill trims.

The model had an edition of 1030 vehicles. It could also be customized with all available extras.

924 50 years of Porsche (1981)

On the occasion of the company's 50th anniversary, Porsche brought out this special series in an edition of around 600 Porsche 924s in tin silver. On the outside, the vehicle differed from the production model by a rear spoiler of the 924 Turbo and the light alloy cross-spoke wheels from ATS in the dimensions 6J × 15 with 205/60-HR-15 wide tires. Instead of clear glass, the car was equipped with tinted windows. The model had electrically adjustable and heated exterior mirrors as standard.

The interior was very extensive and of high quality. The partial leather seats were covered with black and silver pinstripe seat inlays. "Ferry Porsche" was embroidered on the headrests of the front seats. The fabric of the door panels matched the seats. A four-spoke leather steering wheel, electric windows, a stereo radio with a cassette tray rounded off the equipment.

A removable roof could be ordered as an optional extra.

In addition to the 924, 140 Porsche 928 and 200 Porsche 911 SC in meteor metallic were also offered in this special model variant.

924 Weissach (1981 - only USA)

Porsche only brought out this special model based on the Porsche development center in Weissach in the USA. The car was painted in platinum metallic and had ATS light alloy wheels in a cross-spoke design with 205/60 HR-15 wide tires. The chassis was designed sporty with sport shock absorbers and a stronger front stabilizer.

A windshield wiper and the spoiler from the 924 Turbo were mounted at the rear. The standard equipment of the car also included electrically adjustable, heated exterior mirrors, a removable roof, sports seats and door panels covered with beige and white fabric, a three-spoke leather steering wheel and a leather gear knob, electrically operated windows and air conditioning including a larger 63 Ah battery.

The model had an edition of 400 pieces.

924 Turbo (1984 - Italy only)

After its introduction in 1979, the series 924 turbo was taken off the market again in 1982, as the Porsche 944 with a similarly powerful engine and sportier look was met with more interest from buyers.

Only in Italy, where due to tax legislation the expenses for vehicles with a displacement of more than two liters could not be deducted from the tax, the turbo with its 2-liter engine found many buyers. Therefore, the 924 Turbo continued to be manufactured for the Italian market after 1982. From 1984, however, Porsche planned to completely stop production of the turbo.

Shortly before the end of production in the autumn of 1983, the last edition of 88 special vehicles was made for the Italian market. All copies were painted in Zermatt silver metallic and had black leatherette interiors. The seats were covered with anthracite gray / wine-red so-called Porsche fabric, into which the wine-red Porsche logo was woven diagonally at regular intervals .

924 S exclusive model (1988)

At the end of the 924 production, Porsche launched a special model of the 924 S. This exclusive model could be ordered in the paintwork alpine white or black. In England, decorative stripes in ocher yellow / gray were also attached to the white paintwork and turquoise decorative stripes with Le Mans lettering on the sides. This is why this special model was unofficially called "Le Mans".

All models had in common the 2.5-liter engine with 118 kW (160 hp), the light alloy wheels painted in the vehicle color in the "telephone dial design", a sports chassis that lowered the vehicle 10 mm, side protection strips in the vehicle color, splash guards and an electrically operated opening and manually removable targa roof. The interior included a four-spoke leather steering wheel with a diameter of 36 cm and sports seats with flannel fabric covers. The same fabric cover was used for the door panels. The new price was 52,950 DM.

The vehicle was produced 250 times for the German market and 230 times for export around the world. In the US market, this model was only available with modified equipment as the 924 S Special Edition.

924 S Special Edition (1988 - US only)

This special model was only marketed in the USA at the same time as the 924 S exclusive model. The car was painted black and had fewer extras compared to the exclusive model. The equipment was limited to the sports chassis and the sports seats covered with gray / burgundy flannel fabric. In the advertising, Porsche highlighted the reduced standard equipment as a measure to increase the sportiness of the car: "We are leaving out the electric windows, the cassette box and the electric mirrors so that you can enjoy the agility of the 924 S even more!"

500 vehicles were delivered in this version.

Special bodies

Station wagon

In 1981, the Hanover-based tuning company Artz issued a small edition of 20 Porsche 924s that had been converted into station wagons. The basis was the Porsche 924 Turbo with the 125 kW (170 PS) turbo engine. The rear was converted into a station wagon, the front of the vehicle was given the shape of the 924 Carrera GT. The car weighed around 1305 kg and accelerated from zero to 100 km / h in 7.3 seconds.

The so-called Porsche 924 Turbo Kombi cost 62,780 DM.

Open versions

In the 1970s and 1980s, various coachbuilders such as B. the Bieber Cabrio GmbH in Borken convertible conversions of the Porsche 924. The buyer could do the conversion himself or commission the provider to do it. In the case of a self-made conversion, the buyer only received the convertible conversion kit; the costs for this amounted to around 5,000 DM in the 1980s. For the conversion work, 1,000 DM were charged in addition to the kit.

Police vehicle

Porsche 924 formerly used by the NRW police

From the end of the 1970s to the mid-1980s, the state of North Rhine-Westphalia used several Porsche 924s for the motorway police. The vehicles had the typical white and green exterior paintwork, a blue light mounted on the roof, a siren and an electronic stop signal board under the number plate at the rear to display information.

The vehicles are no longer in active use. Only a few are still being moved as ready-to-drive exhibits.

Motorsport

Based on the 924 Carrera GT, Porsche developed three racing car variants for motorsport use.

924 Carrera GTP type 939 (1980)

Porsche 924 Carrera GTP, used in 1981 as the Porsche 944 GTR “Le Mans” with a 2.5 liter engine from the Porsche 944 in Le Mans.

The Carrera GTP was a racing car that Porsche developed specifically for the Le Mans 24-hour race . The basis for the development was the Carrera GT with the 2.0-liter turbo engine. With the same displacement, various changes to the engine and turbocharger resulted in an output of 235 kW (320 hp) at 7000 rpm. To ensure that the engine remained stable, the developers reduced the compression from 8.5: 1 to 7.1: 1.

The body of the Carrera GTP was 10 mm wider and 14 mm longer than that of the Carrera GT. Particularly noticeable was the rear section with a large spoiler and tear-off edges on the rear fender flares. Thanks to a new manufacturing process, the body was particularly torsion-resistant and could be designed to be twice as rigid as the Porsche 935 . The total weight was only 930 kg. The body shape served in a modified form as the basis for the Porsche 944 introduced in 1981 . With the 924 Carrera GTP, Porsche wanted to gain experience for the classes of the SCCA regulations in which the company wanted to operate in the future.

In the 1980 Le Mans 24-hour race , the 924 Carrera GTP with Jürgen Barth and Manfred Schurti finished in 6th place in the overall standings and 3rd place in the GTP class. The other two started Carrera GTP reached positions 12 and 13. After that, the Carrera GTP was no longer used in races.

In 1981, Porsche built the turbo-charged 2.5-liter engine of a Porsche 944 into the body of a Carrera GTP. The engine developed 301 kW (410 hp) at 6500 rpm. At the 24 Hours of Le Mans , this Porsche 944 GTR called “Le Mans” came 7th overall.

924 Carrera GTR type 939 (1981)

Porsche 924 Carrera GTR

The Carrera GTR delivered in 1981 was the homologated racing version that was developed on the basis of the Carrera GTP. It also had a 2.0-liter turbo engine that delivered 276 kW (375 hp) at 6500 rpm. The body of the 19 racing cars produced differed in part from the GTP. The rear fenders did not have a straight edge and, similar to the 924 Carrera GT, formed a flush transition to the rear lights.

The car was sold to private racing drivers at a net price of DM 180,000. Porsche fielded a GTR in the 1981 Le Mans 24-hour race . Although the car driven by Manfred Schurti and Andy Rouse contested about 8 of the 24 hours with only three functioning cylinders due to a valve defect, the works racing team achieved eleventh place in the overall standings and the IMSA GTO class victory.

In addition, private teams also use the Carrera GTR in the sports car world championship in 1981 and 1982 .

924 Carrera GTS type 937 (1981)

Porsche 924 Carrera GTS

The Carrera GTS was another racing car based on the Carrera GT and was developed in 1981 for private racing. As with the GTP and GTR, the engine was a turbocharged 2.0-liter four-cylinder. The compression was limited to 8.0: 1 and the boost pressure increased from 0.75 to 1.0 bar. This engine developed 180 kW (245 hp) at 6250 rpm.

The weight has been reduced by approx. 50 kg to 1121 kg compared to the GT. This was achieved by eliminating damping material, dispensing with comfortable interior fittings and using lightweight materials on the body. The interior was only covered with black needle felt, and racing seats from the Porsche 935 were used instead of standard seats. Upon request, the vehicle could be delivered with a Carrera GT interior. The doors, the bonnet, the front apron and the flared fenders were made of light fiberglass-reinforced plastic. The pop-up headlights were replaced by built-in headlights that were protected by a plastic cover.

Optional comfort equipment was available. In this version, the doors with power windows as well as the sports seats and the center console including radio from the Carrera GT were installed. In total, the car was only ordered twice in this configuration.

The brake system and the wheels with rim dimensions 7J × 16 on the front and 8J × 16 on the rear axle came from the Porsche 911 Turbo .

The price of a 924 Carrera GTS was 110,000 DM.

Porsche also offered the car in a Clubsport version that, at 1,060 kg, was around 60 kg lighter than the standard GTS. Modifications to the engine, such as For example, by increasing the boost pressure to around 1.1 bar, the output rose to 199 kW (270 hp). The vehicle was lowered at the factory and had aerodynamically designed sports exterior mirrors on the left and right. An aluminum roll cage was installed in the passenger compartment. Additional safety equipment included 6-point belts, a fire extinguisher and an emergency stop switch for the electrical system. This car cost DM 122,091 when new.

The 924 Carrera GTS driven by Walter Röhrl in 1981 during the 2008 Germany Rally

The total of 59 vehicles of the Porsche 924 Carrera GTS were produced exclusively in the color Indian red, 44 of which were delivered in the standard and 15 in the clubsport version. The car could be approved for road traffic via an individual TÜV approval in accordance with the StVZO.

The 924 Carrera GTS was built according to the specifications of Group 4 and could therefore be used in rallies as well as in circuit races. Private teams drove the racing car in the sports car world championship, including the 1000 km race on the Nürburgring in 1983 .

In 1981 Walter Röhrl and his co-driver Christian Geistdörfer drove a Carrera GTS equipped for rallying in several rallies for the Monnet-Porsche team. In the German Rally Championship , the car made 2nd place at its premiere in the Metz Rally. In the following Hessen Rally, Serengeti Safari Rally, Vorderpfalz Rally and Sachs Rally, they each achieved victory with the 924.

The role of the 924 for Porsche

The Porsche 924 sold very well when it was launched and by the end of 1976 48% of Porsche's vehicle sales were achieved with this model.
In 1977 Porsche set a new sales record with more than 26,000 vehicles sold. By April 1978, 50,000 vehicles had already been produced. The relatively inexpensive 924 helped Porsche survive the oil crisis of the 1970s unscathed.

Despite the great sales success, the car always had the stigma of not being a “thoroughbred” Porsche because of many of its components from the VW Group. Despite extensive further developments in the 924 Turbo and 924 S and although many of the parts originally made by Volkswagen and Audi were replaced by their own developments, the nicknames such as “Hausfrauenporsche” or “Audiiporsche” remained.

With the introduction of the successor model, the Porsche 944, the production figures of the Porsche 924 fell significantly: In the 1982 model year, around 11,720 units of the 924 were produced. In the following year, this number halved to around 5,980 vehicles. In contrast, production of the 944 rose from around 3,880 in the 1982 model year to around 14,550 in the following year.

In the mid to late 1980s, sales of the 924 and 944 fell dramatically. The number of vehicles produced fell in the model years 1986 to 1989 from around 30,600 to around 7,780. In 1988, 10,786 vehicles were sold for the first time, more Porsche 911s (excluding the Porsche 930 turbo model) than 924 and 944, which together reached 8,937 vehicles. This trend continued in the following years, so that in 1988 production of the 924 and three years later production of the 944 was discontinued.

A total of more than 150,000 Porsche 924s were produced from 1976 to 1988.
