The Audi 50 is a small car with front-wheel drive . The Audi NSU Auto Union AG vehicle (internal: Type 86) was manufactured from the summer of 1974 to mid-1978 and sold only in Europe.
It was largely identical in construction to the less well-equipped VW Polo I , which was built from 1975 to 1981. Both models were produced on the same line at the Volkswagen plant in Wolfsburg by Audi NSU Auto Union AG at the former NSU factory in Germany and at the giant Wolfsburg plant by Volkswagen.
The Audi 50 took only 21 months from the draft to the first production vehicle. On October 26, 1974, the Audi 50 was presented to dealers.The car was offered as a three-door hatchback with a 1,093 cc (66.7 cu in) petrol engine, producing either 37 kW (50 PS; 50 bhp) or 44 kW (60 PS; 59 bhp) for the LS and GL models, respectively.
The car with a displacement of 1093 cc was available as the Audi 50 LS with 37 kW (50 hp) and was designed for regular gasoline . With better equipment it was called the Audi 50 GL , had 44 kW (60 hp) and the higher-compression engine needed premium petrol.
- PERFORMANCE:1,092 cc
- max power (DIN): 50 hp (36.8 kW) at 5.800 rpm
- max torque (SAE): 56 1b ft. 7.7 kg m (75.5 Nm) at 3,500 rpm
- max engine rpm: 5,800
- power-weight ratio: 30.2 lb/hp (41 'lb/kW), 13.7 kg/hp (18-6 kg/kW)
- acceleration: 0-50 mph (0-80 km/h) 9.6 sec
- consumption: 37.2 m/imp gal, 30.9 m/US gal, 7.6 1 x 100 km.
In August 1976, the Audi 50 GLS replaced the previous GL. The LS could now also be ordered with the more powerful 60 hp engine.
- PERFORMANCE: 50 GLS
- ENGINE compression ratio: 9.5:1
- max power (DIN): 60 hp (442 kW) at 6,000 rpm
- max torque .(DIN): 62 1b ft
- max engine rpm: 6,000
- power-weight ratio: 25.2 lb/hp '(34.2 lb/kW), 11.4 kg/hp (153 kg/kW).
From August 1977, an engine with a displacement of 1.3 liters (1272 cc) was installed in the more powerful variant with 44 kW.
With simple equipment and a smaller engine, the VW Polo came onto the market in the spring of 1975 as an economy version of the Audi 50. Its engine produced 29 kW (40 hp) from a displacement of 900 cm³, the stroke had been reduced from 72 to 59 mm. Instead of an automatic starter on the carburetor , as in the Audi, there was a manually operated choke . As standard, the Polo only had drum brakes , also on the front axle, and cross-ply tires .
More powerful engines and better equipment were not offered for the Polo until the following year. At the beginning of 1977, the Polo, which was still in production, was joined by the Derby notchback variant , which was also developed by Audi in Ingolstadt .For strategic marketing reasons, the VW Group removed the Audi 50 from its model range in July 1978 after only four years and 180,828 units had been produced. metallic paint and sunshine roof as options.
180,822 of the Audi 50 were produced:
