Audi 80 turns 50, the First Million-seller for the brand

Exactly 50 years ago, in the year 1972 when the Summer Olympics was held in Munich, In July 1972, the Ingolstadt based Audi world premiered the B1. The Audi 80 established a new market segment called “compact sedan” or B series for short. The newly developed mid-size car rounds off the then model range of the brand with the four rings. The model’s technology introduced numerous new solutions and was later found in many Volkswagen Group models.

The first compact sedan

The Audi 80 established the B series, was both a pioneer of innovative technology and a trendsetter, and became the first million-seller for the brand with the four rings. With the first Audi 80, known internally as the “B1”, the Ingolstadt-based company hit the bull’s eye in 1972. It was intended to be “modern, but not trendy,” a reliable family car.

On this, then Head of Technical Development at Audi Ludwig Kraus and Volkswagen AG, the new parent company, agreed in the late 1960s. As in racecar construction, head developer Ludwig Kraus had his employees check every part to see where weight could still be reduced without compromising on long-term quality, solidity, and strength. The extremely lightweight Audi 80, which went into production 50 years ago, impressed customers with its sporty handling and low consumption, making it, at the start of the 1973 oil crisis, exactly the right car at the right time. Winning “Car of the Year” the same year, the Audi 80 also won over the international trade press.

First RS model

Oliver Hoffmann, Member of the Board of Management of Audi AG for Technical Development, still appreciates the achievement of his predecessor Ludwig Kraus and team “In an impressive way, the Audi 80 demonstrates that Vorsprung durch Technik is a tradition at Audi.”

The Audi 80 and its successor models have always been pioneers of major innovation. The four-cylinder TDI, the quattro drive with the self-locking center differential, the dual-clutch transmission, and the rear-axle sport differential – not to mention the five-cylinder turbo engines as in the first RS model – have repeatedly demonstrated Audi’s expertise in Vorsprung durch Technik.

Designer Hartmut Warkuss helped to shape the design of the first Audi 80 in the new objectivity style of the 1970s. In 1976, Warkuss was promoted to Head of Audi Stilistics, leaving a lasting impression on the design of several generations in Audi’s B, C, and D series. The Audi 80 rolled off the assembly line in four generations (B1 to B4) until 1994/95, when it was replaced by the Audi A4, known internally as the B5. With this model, the Ingolstadt-based company introduced a new nomenclature for its cars. The Audi A4 is now in its fifth edition, the B9 is available as a sedan and Avant, as an S and RS model, and as the Audi A5 in the Coupé, Sportback, and Cabriolet versions.

Lightweight construction

The two-door base model weighs in at just 835 kilograms – strict lightweight construction is one of the specifications set by Head of Technical Development Kraus. With a wheelbase of 2.47 meters and a length of 4.18 meters, he developed the sedan to be highly compact. Suspension engineer Detlef Banholzer implemented negative steering roll radius for the first time in a European mass-produced vehicle – a solution that greatly improves stability during braking. With the diagonal layout of the hydraulic braking system, Audi puts the safety of passengers and other road users front and center. A torsion crank axle with spring dampers serves as the rear suspension. The front wheels are controlled by McPherson struts and wishbones. The engine of the Audi 80 sits lengthwise in front of the driven front axle, the four-speed transmission behind it.

Four engines were available at market launch, the displacement ranged from 1.3 to 1.6 liters, with power outputs ranging from 55 PS to 100 PS. The design highlight of the lively, straightforward four-cylinder engine is the valve control by overhead camshaft with toothed-belt drive and maintenance-free hydraulic tappets. Head of Technical Development Ludwig Kraus came up with the idea of a modular-design series, designing the four-cylinder overhead camshaft (OHC) engine. Developed by engineer Franz Hauk and team, the engine is known internally as the EA 827 and became the most widely built engine in the VW Group.

A real sales hit

With the new generation of OHC engines and its many technical highlights, the Audi 80 quickly became a sales success for the Ingolstadt-based company. By the end of production in the summer of 1978, more than one million B1 models had been rolled off the assembly line. With the production capacity at the Ingolstadt plant soon no longer sufficient to meet the high demand, the Volkswagen plants in Wolfsburg and Emden were involved in production.

The Asso di Picche, a coupé concept car styled by Giorgio Giugiaro and built by coachbuilder Karmann, demonstrated the sporty potential of the B1 as early as 1973. The Audi 80 GT went to series production in 1973, before being replaced by the Audi 80 GTE in October of 1975. Its engine has a power output of 110 PS. In 1976, the B1 received a model update that gave the sedan large block headlights, visually aligning it more closely to the new generation of the Audi 100. Light and fuel-efficient, the Audi 80 became very popular, especially after the 1973 oil crisis. The car was also a hit in the USA, where it was sold as the “Fox”.
