TALBOT HORIZON – Group B Prototype

In 1979, following the creation of the Talbot brand out of the defunct Chrysler Europe, Rootes, and Simca, parent company PSA decided that the new division needed much publicity to boost its image. The result was a venture into motorsport, partly into F1 and partly into rallying. From this, the Talbot Sunbeam Lotus took part in international rallying from 1979 to 1982 and won the World Championship for Talbot in 1981. Based on this success and the introduction of the new Group B rules, Talbot started devising a prototype to compete in the new class.

Work on a “silhouette” Horizon (which some may remember as the Dodge Omni / Plymouth Horizon) began with a similar concept to the very successful Renault 5 Turbo by using the previous Sunbeam Lotus slant-four “911” engine and moving it from the front of the car to behind the front seats. The Group B Horizon was thus born. Only two prototypes were built before PSA cancelled the project in favor of developing a totally new mid engine, turbocharged, four wheel driven platform to compete head-to-head with the Audi Quattro: the now legendary Peugeot 205 T16.
