The Sunbeam Alpine is a two-seater sports drophead coupé produced by Rootes Group from 1953 to 1955, and then 1959 to 1968.

The name was then used on a two-door fastback from 1969 to 1975. The original Alpine was launched in 1953 as the first vehicle from Sunbeam-Talbot to bear the Sunbeam name alone since Rootes Group bought Clément-Talbot and later the moribund Sunbeam from its receiver in 1935.

The Alpine was derived from the Sunbeam-Talbot 90 Saloon, and has become colloquially known as the "Talbot" Alpine. It was a two-seater sports roadster initially developed for a one-off rally car by Bournemouth Sunbeam-Talbot dealer George Hartnell. It had its beginnings as a 1952 Sunbeam-Talbot drophead coupé. Announced in March 1953 it received its name following Sunbeam-Talbot saloons successes in the Alpine Rally during the early 1950s. On its first competitive outing, the July 1953 Coupe des Alpes, the new car won the Coupe des Dames (Sheila van Damm) and, without loss of any marks, four Coupes des Alpes driven by Stirling Moss, John Fitch, G Murray-Frame and Sheila van Damm.

The car has a four-cylinder 2,267 cc (138.3 cu in) engine from the saloon, but with a raised compression ratio. However, since it was developed from the saloon platform, it suffered from rigidity compromises despite extra side members in the chassis. The gearbox ratios were changed, and from 1954 an overdrive unit became standard. The gearchange lever was column-mounted. A true open 2-seater there were no external door handles or wind-up windows.

Open two-seater (without wind-up windows)   1954 The Alpine Mark I and Mark III (no Mark II was made) were hand-built – as was the 90 drophead coupé – at Thrupp & Maberly coachbuilders from 1953 to 1955, and remained in production for only two years. Of the 1582 automobiles produced, 961 were exported to the USA and Canada, 445 stayed in the UK, and 175 went to other world markets. It has been estimated that perhaps as few as 200 have survived.[when?] The Sunbeam Alpine Mk 1 Special: It was based on the 2267cc Mk 1 Sunbeam Talbot motor, with alloy rocker cover and Siamese exhaust ports [ cylinders 2 and 3 ]. These motors developed a reputed, 97.5 bhp at 4,500 rpm, mainly by raising the compression ratio to 8.0:1 and incorporating a special induction manifold with a twin choke Solex 40 P.I.I carburettor . Sunbeam Alpine Team Cars : MKV 21 - 26: The motors were configured the same as the Sunbeam Alpine Mk I Special, with further tuning by ERA to raise power to 106 bhp.

Very few of these cars are ever seen on the big screen. However, a sapphire blue Alpine featured prominently in the 1955 Alfred Hitchcock film To Catch a Thief starring Cary Grant and Grace Kelly. More recently, the American PBS show History Detectives tried to verify that an Alpine roadster owned by a private individual was the actual car used in that movie. Although the Technicolor process could "hide" the car's true colour, and knowing that the car was shipped back from Monaco to the USA for use in front of a rear projection effect, the car shown on the programme was ultimately proven not to be the film car upon comparison of the vehicle identification numbers.

The first open 2-seater Alpines were based on the Hillman 14 and its successor the Humber Hawk. Rootes replaced them with a softer new smaller 2-seater sports convertible coupé based on the current Hillman Minx and its variants. Kenneth Howes and Jeff Crompton were tasked with doing a complete redesign in 1956, with the goal of producing a dedicated sports car aimed principally at the US market. Ken Howes contributed some 80 per cent of the overall design work, he had worked at Ford before joining Rootes.

The Alpine was produced in four subsequent revisions until 1968. Total production numbered around 70,000. Production stopped shortly after the Chrysler takeover of the Rootes Group.

Series I 1959–60

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) discs at the front and 9 in (229 mm)drums at the rear.

Coupé versions of the post-1959 version were built by Thomas Harrington Ltd. After the Le Mans Index of Efficiency success of 1961, Harrington sold replicas as the "Harrington Le Mans", using a fastback body and an engine tuned to 104 hp (78 kW). Unlike the Le Mans racers, these cars had a more integrated rear roofline and were without the tail fins of the roadsters. 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 (9.0 L/100 km; 26.1 mpg_‑US) was recorded. The test car cost £1031 including taxes.

11,904 examples of the series I were produced.

In 1960 Rootes Group 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 I used a 1,494 cc (91.2 cu in) engine and was styled by the Loewy Studios for the Rootes Group. It had dual downdraft carburetors, a soft top that could be hidden by special integral covers and the first available wind-up side windows offered in a British sports car of that time.

Series II 1960

The Series II of 1960 featured an enlarged 1,592 cc (97.1 cu in) 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 (9.1 L/100 km; 25.8 mpg_‑US). The test car cost £1,110 including taxes.

Series III 1963–64

The Series III was produced in open and removable hardtop versions. On the hardtop version the top could be removed and the soft-top was stored behind the small rear seat; also the 1592 cc engine was less powerful. To provide more room in the boot, twin fuel tanks in the rear wings were fitted. Quarter lights were fitted to the windows. Between 1963 and 1964, 5863 were made.

Series IV 1964–65

There was no longer a lower-output engine option; the convertible and hardtop versions shared the same 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.

Series V 1965–68

The final version had a new five-bearing 1,725 cc (105.3 cu in) engine with twin Zenith-Stromberg semi-downdraught carburettors producing 93 bhp. There was no longer an automatic transmission option. 19,122 were made. In some export markets, 100 PS (99 bhp) SAE were claimed.

A muscle-car variant of the later versions was also built, the Sunbeam Tiger.

Competition

The Alpine enjoyed relative success in European and North American competition. Probably the most notable international success was at Le Mans, where a Sunbeam Harrington won the Thermal Index of Efficiency in 1961. In the United States the Alpine competed successfully in Sports Car Club of America (SCCA) events.

Vince Tamburo won the G-Production National Championship in 1960 using the 1494cc Series I Alpine. In 1961 Don Sesslar took 2nd in the F-Production National Championship followed by a 3rd in the Championship in 1962. For 1963 the Alpine was moved into E-Production facing stiff competition from a class dominated by the Porsche 356. Sesslar tied in points for the national championship while Norman Lamb won the Southwest Division Championship in his Alpine.

A championship for Don Sesslar finally was achieved in 1964 with 5 wins (the SCCA totaled the 5 top finishes for the year). Dan Carmichael won the Central Division Championship in 1964 and '65. Carmichael continued to race the Alpine until 1967, when he finished 2nd at the American Road Race of Champions.

Bernard Unett raced factory prototype Alpine (registration number XRW 302) from 1962 to 1964 and in 1964 won the Fredy Dixon challenge trophy, which was considered to be biggest prize on the British club circuit at the time. Unett went on to become British Touring car champion three times during the 1970s.

A six-car works team was set up for the 1953 Alpine Rally. Although outwardly similar to their production-car counterparts they reputedly incorporated some 36 modifications, boosting the engine to an estimated 97.5 bhp.

Rootes introduced the "Arrow" range in 1966, and by 1968 the saloons and estates (such as the Hillman Hunter) had been joined by a Sunbeam Rapier Fastback coupé model. In 1969, a cheaper, slightly slower and more economical version of the Rapier (still sold as a sporty model) was badged as the new Sunbeam Alpine.

All models featured the group's strong five-bearing 1725 cc engine, with the Alpine featuring a single Zenith-Stromberg CD150 carburettor to the Rapier's twins, and the Rapier H120's twin 40DCOE Weber carburettors.

Although drawing many parts from the group's "parts bin", including the rear lights of the estate Arrow models, the fastbacks nevertheless offered a number of unique features, including their pillar-less doors and rear side windows which combined to open up the car much like a cabriolet with a hardtop fitted. Extensive wooden dashboards were fitted to some models, and sports seats were available for a time.

Post-Sunbeam Alpine

The Alpine name was resurrected in 1976 by Chrysler (by then the owner of Rootes), on a totally unrelated vehicle: the UK-market version of the Simca 1307, a French-built family hatchback. The car was initially badged as the Chrysler Alpine, and then finally as the Talbot Alpine following Chrysler Europe's takeover by Peugeot in 1978. The name survived until 1984, although the design survived (with different names) until 1986.
