The "Series" Alpine started production in 1959. One of the original prototypes still survives and was raced by British Touring car champion Bernard Unett.
The car made extensive use of components from other Rootes Group vehicles and was built on a modified floorpan from the Hillman Husky estate car. The running gear came mainly from the Sunbeam Rapier, but with front disc brakes replacing the saloon car's drums. An overdrive unit and wire wheels were optional. The suspension was independent at the front using coil springs and at the rear had a live axle and semi-elliptic springing. The Girling-manufactured brakes used 9.5 in (241 mm) disc at the front and 9 in (229 mm)drums at the rear. Coupe versions of the post-1959 version were built by Thomas Harrington Ltd. Until 1962 the car was assembled for Rootes by Armstrong Siddeley.
An open car with overdrive was tested by the British magazine The Motor in 1959. It had a top speed of 99.5 mph (160.1 km/h) and could accelerate from 0–60 mph (97 km/h) in 13.6 seconds. A fuel consumption of 31.4 miles per imperial gallon (9.00 L/100 km; 26.1 mpg-US) was recorded. The test car cost £1031 including taxes.
In 1960 Sunbeam marketed a limited-production three-door variant of the Alpine, marketed as a shooting brake. With leather interior and walnut trim, its price was double that of its open counterpart.
The Series II of 1960 featured an enlarged 1592 cc engine producing 80 bhp and revised rear suspension, but there were few other changes. When it was replaced in 1963, 19,956 had been made. A Series II with hardtop and overdrive was tested by The Motor magazine in 1960, which recorded a top speed of 98.6 mph (158.7 km/h), acceleration from 0–60 mph (97 km/h) in 13.6 seconds and a fuel consumption of 31.0 miles per imperial gallon (9.11 L/100 km; 25.8 mpg-US). The test car cost £1,110 including taxes.
The Series III was produced in open and removable hardtop versions. On the hardtop version the top could be removed but no soft-top was provided as the area it would have been folded into was occupied by a small rear seat. Also, the 1592 cc engine developed less power. To provide more room in the boot, twin fuel tanks in the rear wings were fitted. Quarter light were fitted to the windows. Between 1963 and 1964, 5863 were made.
The lower-output engine option was now dropped with convertible and hardtop versions sharing the 82 bhp engine with single Solex carburettor. A new rear styling was introduced with the fins largely removed. Automatic transmission with floor-mounted control became an option, but was unpopular. From autumn 1964 a new manual gearbox with synchromesh on first gear was adopted in line with its use in other Rootes cars. A total of 12,406 were made.
The final version had a new five-bearing 1725 cc engine with twin Zenith-Stromberg
