Audi 80 B1
Audi 80 B1 (1972-76): This model debuted in Europe in 1972 (with factory production starting in May 1972) as the Audi 80, and in 1973 in Australia and the United States as the Audi Fox, and was available as either a two-door or a four-door saloon (sedan). It effectively took the place of several models that Audi had discontinued (the F103 series, which included the first model designated as an "Audi 80"), and provided the company with a viable rival to the Opel Ascona and the Ford Taunus.
The Audi 80 was first equipped with 1.3- and 1.5-litre SOHC straight-4 petrol engines. The internal combustion engines were available in various rated power outputs. For the 1.3 L engines, (identification code: ZA) was rated at 55 PS (40 kW; 54 bhp), code: ZF was rated at 60 PS (44 kW; 59 bhp). The 1.5 L (codes: ZB, ZC) at 75 PS (55 kW; 74 bhp) for the ZB and 85 PS (63 kW; 84 bhp) for the ZC.
On the home market, two- and four- door saloons were available in base trim (55 or 60 PS, called simply Audi 80 and 80 S, respectively), as L models (LS with 75 PS engine) or as a more luxurious GL (85 PS only). In September 1973, Audi added the sporty 80 GT (two-door only) featuring a carburetted 1.6-litre engine (code: XX) rated at 100 PS (74 kW; 99 bhp).
The Audi 80 had a MacPherson strut front suspension, and a C-section beam rear axle located by trailing arms and a Panhard rod, and using coil springs and telescopic dampers.
Audi's design and development efforts paid off during the 1973 European Car of the Year competition where the 80 won ahead of the Renault 5 and the Alfa Romeo Alfetta.
A facelift in autumn 1976 brought about a revised front end in the style of the newly introduced Audi 100 C2 with square instead of round headlights, 1.6- instead of 1.5-litre engines (still of 75/85 PS) and a new 80 GTE model with a fuel-injected version of the 1.6-litre (110 PS (81 kW; 110 bhp)) replacing the former 80 GT.
The Fox had a 1.5 L engine rated at 55 hp (41 kW; 56 PS) attached to a four-speed manual transmission. Subsequent versions came with 1.6 L engines rated at 83 hp (62 kW; 84 PS).
In certain markets a five-door "Avant" (Audi's name for an estate/wagon) variant was offered — effectively a rebadged Volkswagen Passat with Audi front panels. The B1 platform was dropped from the European market in 1978, although it was sold into the 1979 model year in North America.
