Early Days: The Alpine’s Racing Genesis (1953-1955)

The story of the Sunbeam Alpine doesn’t begin with a production car; it starts on the race track. The name “Alpine” was first employed by the Rootes Group in 1953 for a special competition version of their Sunbeam-Talbot.

The original Alpine race car, based on the Sunbeam-Talbot 90, featured a modified chassis, a higher-compression engine, and a lightweight body. This was no ordinary road car; it was a meticulously crafted racer designed for performance and reliability over challenging terrain. The car’s success in the Alpine Rally, finishing in the top ranks, solidified its reputation and sparked the desire for a road-going version that could capture the same spirit of adventure.
