The Aston Martin’s reputation has always far transcended its small-scale production. The first prototype was evolved by Lionel Martin and Robert Bamford in 1914, the Aston part of the name deriving from the Aston Clinton hill-climb. It used a 1.4-litre side-valve Coventry-Simplex engine in an Isotta-Fraschini voiturette chassis, and was followed by a second Aston Martin prototype in 1919. Aston Martin production started in 1922 with a larger 1½-litre side-valve engine in a chassis with 4-speed gearbox and semi-elliptic springs all round. A complete Aston Martin car for sale cost £850, and about 60 were made up to 1925. Successes included 2nd place in the 1922 200-Mile Race at Brooklands, and the collection of a number of world records in the same year. Front-wheel brakes were standard from 1923, and several overhead-camshaft engines were evolved for racing, initially of single-cam type, but later in 16-valve (1922) and 8-valve (1924) twin-cam forms, the former developing 54bhp. These Aston Martin cars were generally less successful than the production side-valves. The Aston Martin company exhibited at Olympia in 1925, but was wound up a few weeks later.

A comeback was staged in 1926, the new Aston Martin machine being an ohc 1½-litre designed by A.C. Bertelli. This was tested in an Enfield-Allday racing chassis and went into production at Feltham in 1927 in 50bhp form, with 4-speed separate  gearbox, dash-mounted steering box, and David Brown worm final drive. Bodies were the work of Bertelli’s brother Enrico, and early Aston Martin sports models weighed only 2.128lb complete. A 63bhp dry-sump competition engine was made in 1928, and two dozen Aston Martin cars had been delivered by 1929. The dry-sump engine was standardized in 1930 and the Aston Martin 1½-litre model had a long and distinguished competition history: 6th in the ‘Double-12’ at Brooklands in 1931, the award of the Biennial Cup at Le Mans in 1932, 5th at Le Mans in 1933 and 3rd in 1935, in which year a class win was recorded in the Mille Miglia. In 1938, two years later the Aston Martin 1½-litre had gone out of production, Polledry took 2nd place in the Bol d’Or 24-Hour Race, and a similar car was actually 5th as late as 1951.

Finance was always a problem; there was a brief marketing link with Frazer Nash in 1931 and in 1933 the Aston Martin firm came under the direction of R.G. Sutherland, who retained control until after World War 2. In 1932 the Aston Martin 1½-litre acquired bevel drive and a unit gearbox of Moss make, being sold in 55bhp touring and 70 bhp sports versions, while the handsome Aston Martin MkII of 1934-1936, though it now weighed 2.576lb, was capable of 85mph and sold for £610. Aston Martin’s best sales year was 1933 with 105 cars delivered. The 80bhp Aston Martin Ulster model of 1935 could exceed 100mph. An Aston Martin 2-litre model, still with ohc was prepared for the cancelled 1936 Le Mans race and replaced the 1½-litre the following season, with wet-sump lubrication, synchromesh gearbox and Girling brakes at £575; a dry-sump Aston Martin Speed Model version was still available for £200 more. Prices were slashed to £495 in 1939, in which year the Aston Martin Speed Model was sold with aerodynamic bodywork and the Cross rotary-valve engine was tried, but not adopted. There were also wartime experiments with the Atom saloon with tubular chassis-body structure and Cotal gearbox, but the first post-war Aston Martin for sale, a Claude Hill design, featured a short-stroke pushrod 2-litre engine, independent front suspension, a hypoid back axle, hydraulic brakes and, for the first time, coil ignition. One of these Aston Martin cars won at Spa in 1948, but very few were made, even after the acquisition of the company by David Brown group in 1947.

In 1949 the 2.6-litre twin ohc 6-cylinder engine designed by W.O. Bentley for Lagonda (also part of the David Brown empire) was installed in an aerodynamic Aston Martin coupé using a space-frame with square-section tubes. It ran at Le Mans, reaching production status in 1950 as the Aston Martin DB2 available in 107bhp and 123bhp Aston Martin Vantage forms at a price of £1.915. These cars did well at Le Mans in 1950 and 1951, as well as winning their class in the 1951 Mille Miglia; they led to some out-and-out sports-racing machines, the Aston Martin DB3 (for sale in 1952), with Eberhorst-designed structure and 5-speed gearbox, and the 2.9-litre Aston Martin DB3S (for sale in 1953), which developed  210bhp and reverted to four forward speeds. Three wins in the Goodwood 9-Hour Sports-Car Race, and place at Sebring and 5th in the Mille Miglia in 1953, and twosuccessive 2nd places at Le Mans (1955 and 1956) made the David Brown Astons a powerful force in international racing. The touring Aston Martin DB2 acquired rather occasional rear seats in 1954 and a 140bhp 2.9-litre engine in 1955.

1956 saw the first of two unsuccessful forays into Formula I (the second was in 1959), and the début of the Aston Martin DBR series of sports-racers with space frames and De Dion rear axles, the first Aston Martins to have disc brakes. These were raced in 2.5-, 2.9-, and 3.7-litre forms and scored three successive wins in the Nürburgring 1000-Kilometre race, a win at Spa in 1957, a 1-2-3 victory in the 1958 T.T., and finished 1st and 2nd at Le Mans in 1959. Also in 1959 Aston Martin became the first and only British makers to win the Sports Car Constructors’ Championship. The MkIII version of the Aston Martin DB2/4 (for sale in 1957) had front disc brakes, and could be had with overdrive or automatic gearbox – factory options which are found on all later Aston Martins. Manufacture was transferred to the former Tickford body works (which had made the N.P. car in the 1920s) at Newport Pagnell in 1958. 1959 saw a detuned 240bhp version of the 3.7-litre DBR engine installed in the Aston Martin DB4, an Italian-styled sports saloon with platform frame, trailing-link and coil rear suspension and all-round disc brakes. A 302bhp short-chassis GT version capable of 170mph followed in 1960. A 255bhp Vantage engine was an option on the standard chassis in 1962, and the 4-litre Aston Martin DB5 for sale in 1964  had alternator ignition, a diaphragm clutch and the new transmission option of five forward speeds. The 5-speed box was standard in the 282bhp Aston Martin DB6 which sold in 1966 for £5.084. A 325bhp Vantage version was also available. An additional 1967 Aston Martin model had coupé bodywork by Superleggera Touring of Italy – a return to two-seaters after a lapse of several years. In December 1966 it was announced that the Aston Martin company was developing a 5-litre V8 racing engine to be installed in a Lola chassis. New for 1968 was the Aston Martin DBS coupé with four headlamps and De Dion rear axle, and in 1970 Mk2 versions of the Aston Martin DB6 had power steering as standard and fuel injection as a regular option. A new Aston Martin DBS was powered by Aston Martin’s V8, a 4ohc 5.4-litre unit developing 375bhp; transmission options were a 5-speed ZF gearbox or Chrysler Torqueflite automatic. In 1972 Ogle produced their Karen-styled version of this car with 22 rear lamps, Sundym glass and headlamp washers. Aston Martin changed hands in April of that year, and the 6-cylinder cars were discontinued.

Pontiac

US, 1907 – 1908

Pontiac Spring and Wagon Works, Pontiac, Mich.

The Pontiac car was a two-seater high-wheeler with right-hand steering by wheel. The Pontiac car was powered by a 2-cylinder, water-cooled engine mounted under the body. The drive of the Pontiac car was through a friction transmission and double chains to the rear wheels. The cost of the Pontiac car was $600.

US, 1915

Pontiac Chassis Co, Pontiac, Mich.

A chassis without body was all that this Pontiac car company marketed. This Pontiac car chassis was furnished with a 4-cylinder engine, by Perkins, rated at 25hp, driving through a 3-speed transmission.

US, 1926 to date

(1) Oakland Motor Car Co, Pontiac, Mich., 1926 – 1932

(2) Pontiac Motor Co, Pontiac, Mich., 1933 to date

Oakland’s Pontiac Six was intended as a lower-priced running mate, and prices of this conventional 3-litre sv six Pontiac cars started at $825. Only closed bodies were offered initially, but a sales of over 140.000 Pontiac cars was an indication of acceptance, especially when followed by an increase to 210.890 Pontiac cars in 1928. The 1930 Pontiac cars closely resembled Buick’s Marquette, and had 3.3-litre engines, the six being joined in 1932 by a V8 which Pontiac car was really a revamped 1931 Oakland.

In 1933 Pontiac car company scored an important success with a 3.7-litre, 77bhp straight-8 Pontiac car selling for less than $600 with General Motors’ new no-draught ventilation, the 6-cylinder Pontiac cars being dropped for the time being. The 1934 Pontiac cars had Dubonnet-type independent front suspension, and ‘turret-top’ all-steel bodies. Fencer’s mask radiator grilles were found on the 1935 Silver Streak line of Pontiac cars. Capacities of the six and the eight were 3.6-litres and 4.1-litres respectively in 1937. In 1939 Pontiac car company’s cheaper cars had body shells very similar to those of the Chevrolet, as befitted a make which ranked next in the GM hierarchy – though in fact only $20 separated the cheapest Pontiac car, the 4-door sedan from the corresponding Oldsmobile model.

Pontiac cars Torpedo Streamliners brought back the fastback style in 1941, and the immediate pre-war Pontiac cars were continued with little alteration until 1949, when the whole group’s products were restyled, and Pontiacs emerged with lower bodies, redesigned X-frames, and the option of Hydramatic transmission. Though maintaining high sales – they beat Plymouth cars into 4th place overall in 1954 – Pontiac cars remained conservative in engine design, and the well-tried 127bhp sv straight-8 Pontiac car was not supplanted until 1955, when all US-produced Pontiac cars received a 4.7-litre ohv V8. The L-head six was retained for some Pontiac cars made for the Canadian market.

Along with some of the other staider American makes, such as Plymouth and Mercury, the Pontiac car company stove to build their reputation on performance in the later 1950s; the 1958 Pontiac Super Tempest attained 330bhp, and in 1959 Pontiac car came out with a wide-track chassis and concentrated on a 6.4-litre V8 available in a variety of powers from 245 to 345hp.

The Pontiac Car Division’s compact, the Pontiac Tempest arrived in 1961, and was an unusual ohv oversquare four of 3.2-litres’ capacity, mounted in a unitary-construction hull, with its 3-speed synchromesh gearbox in the rear axle. Floor change was standardon the Pontiac car: it was listed at $2.240. A small V8 Pontiac car was available as an option in 1963. The big Pontiac cars went over to GM’s perimeter-type frame in 1963, when the V8 engine was available in a variety of guises on the Pontiac car, from a ‘cooking’ 215bhp version burning regular-grade petrol at $2.725 up to the sporting Pontiac Grand Prix coupé with 303bhp and a revolution counter as standard equipment, at $3.489. The Tempest’s 4-cylinder engine was dropped on the Pontiac car in 1965 in favour of a 140bhp six or 5.4-litre eight. Sporting qualities were emphasized in 1966, by which time the Pontiac Tempest had grown from a 9ft 4in wheelbase to 9ft 8in, and the range of Pontiac cars included the Pontiac GTO Grand Prix and 2 plus 2 models, all Pontiac cars disposing of more than 330bhp from engines of 6.4 and 6.9 litres’ capacity. In 1967, 3.8-litre ohc 6-cylinder engines were introduced: in the sporting Pontiac Firebird Sprint this unit developed 215bhp.

By 1970 the more sporting Pontiac cars (GTO, Firebird and Grand Prix) had front disc brakes, and all full-sized Pontiac cars came with automatic transmission as regular equipment. New for 1971 was a compact Pontiac car, the Pontiac Ventura II on a 9ft 3in wheelbase. The 1972 Pontiac car range covered most sectors of the market, from the Pontiac Ventura at $2.394 up to the luxury Pontiac Grand Ville with 220bhp 7.456cc V8 engine at $4.368. For the sporting motorist there were the Pontiac Le Mans Sport, the Pontiac GTO, and a wide selection of Pontiac Firebirds up to the Pontiac Trans Am with 300bhp V8 unit, giving the Pontiac car a top speed of about 120mph. Peculiar to Canada was the Laurentian, a hybrid Chevrolet-Pontiac on a 10ft 3½in wheelbase, available with  110bhp 6-cylinder or 165bhp V8 unit. In the main 1973’s improvements concerned styling, the Pontiac cars being longer and wider, but new Pontiac cars were the Grand Am 2- and 4-door hardtops, with 6½- or 7½-litre V8 engines, power steering, power disc front brakes and 3-speed automatic gearbox.
