Karl Benz is honoured throughout the world as the man who designed and built the first workable motor car driven by an internal combustion engine. It is established that in 1885 his first Benz car was ready and made its first trials. Benz’s ideas were concentrated from the beginning on a car as an organic unit of chassis and engine, not on motorization of existing vehicles. The first Benz car was a three-wheeler with two driven rear wheels. The engine was a horizontal single-cylinder with a vertical crankshaft which had a horizontal flywheel. It developed ¾hp and a speed of 8mph is recorded for one of the first trial runs. This prototype Benz car had some featured which are still very extensively used in automobile construction: the water-cooled engine, electric ignition, mechanically operated inlet valve, and a differential gear. This first Benz car still exists and belongs to the Deutsches Museum, Munich, to which it was presented by its inventor. Several Benz Patentwagen replicas were built and are now in different museums.

Only a few Benz cars were produced and for sale in the following years. At the Munich Exhibition of 1888 Benz had the opportunity of showing his improved Benz car to a wider public. Instead of the wire wheels of the first Benz Patentwagen the later models had wooden-spoked wheels. Engine output was increased to 2hp. Sales of Benz’ stationary gas engines were quite satisfactory, while interest in Benz motor cars was very limited and it was not until 1890 that Benz started a real, if small, ‘to order’ production. This was partly a result of exhibiting his Benz car at the Paris World Fair in 1889 which led to increasing sales by his French agent Emile Roger, who already sold Benz stationary engines. The other important factor was that Benz was joined by two new partners in 1890. These two men who possibly saved Benz from the fate of numerous other inventors, driven aground by financial difficulties, were Friedrich von Fischer and Julius Ganss. Fischer took over internal administration and Ganss became responsible for sales. Benz himself was free for further developments on the technical side of the business, which made sound progress. 1893 saw the production of the first 4-wheeled Benz car, the Benz Victoria. This model was also the basis for the first Benz van and Benz bus in 1895; its technical conception was also adopted for the Benz Velo of 1894. This model has a place in the history of motoring as the world’s first production car. Production figures for 1885 to 1893 were 69 cars. 67 cars left the factory in 1894, mainly Benz Velos. These figures increased to 135 cars in 1895 and 181 in 1896.

In 1896 the first Benz Kontra-Motor appeared, an engine with two horizontally opposed cylinders. The first Benz lorry was produced in the same year. In 1898 pneumatic tyres were adopted for the Benz Comfortable. Production in 1899 was 572 cars, which brought Benz into the first rank of car producers. This number was surpassed in the following year with a production of 603 units. The first Benz racing car appeared in 1899 and was the start of numerus racing successes.

After 1901 sales of Benz cars declined as Benz stuck to his now outdated designs. Mercedes’ successes led him to evolve new concepts of construction; the result was the 2-cylinder front-engined Parsifal presented in 1903, available with cardan or chain drive and various engine outputs. In the same year a new 4-cylinder engine appeared and was used in all subsequent Benz models. A 1903 racing car developed 60hp and participated in the Paris-Madrid race. Karl Benz himself left the company in 1903 although he rejoined shortly afterwards. In 1906 he joined his sons in the firm of C. Benz Söhne.

1906 saw Benz gaining a second place in the Herkomer Trial while in the same event in 1907 a 5hp Benz finished first. Second and third place in the Coppa Florio, 1907, first place in the Florida 100-Miles Race, 1908, second and third place in the French Grand Prix, 1908, and second and fourth place in the American Grand Prix, 1908, led the world records which were set with 150hp and 200hp Benz cars by Bruce-Brown, Robertson, Oldfield and Hémery. With the 200hp Blitzen Benz Burman covered a mile in 25.4 seconds from a flying start at Daytona Beach in 1911. This was a speed of 140.8mph, but was not recognized internationally as a Land Speed Record.

In 1910 Benz acquired the Süddeutsche Automobil-Fabrik of Gaggenau. Production of private Benz cars in this factory was given up and in the following years Benz concentrated on commercial vehicles there.

A wide range of Benz cars for sale was marketed in the 1910-1914 period, ranging from the 2-litre Benz 8/20ps up to really big machines like the 10.1-litre Benz 39/100ps, all with side valve engines and shaft drive. However, the 22-litre Benz 200hp (which cost £1800 in England in 1912, and must have been the largest-engined private car to go on the market) had ohv and final drive by side chains. Benz were successful in the Austrian Alpine Trials, the Tatra-Adria Trial and various trials in Russia, to name only a few. The great promoter of German motoring, Prince Henry of Prussia, used only Benz cars.

The first Benz 6-cylinder car was produced in 1914 with the type Benz 25/65ps 6.5 litre. In 1918 the Benz 6/18ps 4-cylinder 1540cc appeared, a type developed during the war. A very important Benz development was the precombustion chamber diesel engine. It was first used in 1922 for Benz Sendling agricultural tractors, and the first diesel-engined lorry by Benz appeared in 1924. These were steps towards later Mercedes-Benz diesel-engined cars. Another idea introduced by Benz which also appeared in later Mercedes-Benz cars was the swing axle. It was one feature of the 2-litre 6-cylinder Benz ‘teardrop’ racing car designed on Rumpler principles. However, this car was not a great success either in its racing or in its sports version. In the Grand Prix of Italy in 1923 they gained fourth and fifth place. In 1924 Benz and Mercedes began to combine their interests, amalgamating in 1926.

Cadillac

US, 1903 to date

(1) Cadillac Automobile Co, Detroit, Mich., 1903 – 1905

(2) Cadillac Motor Car Co, Detroit, Mich., 1905 to date

The ‘Standard of the World’ started humbly as a single-cylinder car selling for $750. Henry M. Leland, its creator, had been associated with Henry Ford and has also built engines for Oldsmobile. The Model-A Cadillac was markedly similar to the early Fords in having a horizontal underfloor engine, 2-speed planetary transmission and central chain drive via a spur-type differential, but Cadillac’s 1½-litre inlet over exhaust power unit had one cylinder where Ford used two. There was no bonnet on the early Cadillac models. This very successful design remained in production until 1908, later improvements including rack-and-pinion steering, transverse front suspension and a dummy bonnet. The Cadillac marque was introduced to Britain by F.S. Bennett, who in 1908 conducted a ‘standardization test’ at Brooklands. Three single-cylinder Cadillac cars were dismantled and the parts mixed up – they were then reassembled and the vehicles run on the track. The R.A.C. awarded Cadillac the Dewar Trophy for this achievement.

A 30hp 4-cylinder Cadillac car with separate cylinders and copper jackets was announced for 1906 and 75.000 of this type Cadillac were sold before it was discontinued in 1914. The original planetary transmission gave way first to a conventional 3-speed box, and finally in 1914 to a 3-speed box with 2-speed back axle. Cadillac was one of the firms organized into the General Motors group in 1909 by W.C. Durant, and in 1910, when a 4-cylinder Cadillac tourer could be bought for $1600, the company was claiming that tolerance on 112 parts of the car were accurate to one-thousandth of an inch. 1912 saw a most important Cadillac innovation: the standardization of the Delco system of electric lighting and starting on the Cadillac, now of 5½-litres capacity and capable of 60mph. The first left-hand drive Cadillac of 1915 was also the first of the company’s V8s, to become as much a hallmark of the breed as were Buick’s overhead valves. Inspired by the De Dion Bouton of 1910 it had 5.1-litre engine and sold for $2700. 13.000 V8 Cadillac  cars were sold in the first year of production and the model was widely used by the U.S. Army in World War 1. Cylinder heads were detachable from 1917 on, and 1924 Cadillac versions had Duco cellulose finish and front wheel brakes.

In 1927, when 47.000 Cadillac cars were sold, a less expensive companion make, La Salle appeared, and the cars were restyled in 1928. The synchromesh gearbox made its world debut with the 1929 Cadillac models, which also featured chromium plating and safety glass, with a price range from $3.295 to $5.995. 1930 saw the advent of the ohv Cadillac V16 of 7.4-litres, which gave 185bhp and had a wheelbase of 12ft 4in. This sold at an average rate of 500 Cadillac cars a year for eight seasons in the $6.000-$9.000 price backet. It was joined in 1931 by an equally impressive ohv 6-litre V12 Cadillac for sale. Improvements over the next few years included power brakes (1931), ride control (1932), no-draught ventilation (1933), Dubonnet type independent front suspension (1934) and ‘turret-top’ all-steel bodies (for sale in 1935). 1938 Cadillac models had column change as standard, a year ahead of other GM products, while the V12 and V16 were dropped in favour of a side-valve short-stroke Cadillac 16-cylinder model which was made until 1940. Another new model for Cadillac in 1938, the 8-cylinder Cadillac Sixty Special, anticipated GM’s 1940 styling with its absence of running boards and 4-light sedan bodywork. 5.7-litre side-valve V8s in three wheelbase lengths made up the 1941 Cadillac range, on which Hydramatic transmission was optional for the first time.

The post-war era was to see Cadillac outstrip all its competitors in the top-price class and become an international symbol of wealth. Sales climbed from 66.000 cars in 1941 to 103.857 Cadillac cars in 1950, and to a new record of 165.959 Cadillac cars in 1964. Tail fins made their first appearance on Cadillac’s 1948 fastback coupé, and in 1949 Cadillac, along with Oldsmobile, adopted overhead valves and oversquare cylinder dimensions, their new 5.4-litre engine developing 160bhp. Cadillacs were raced at Le Mans in 1950 by Briggs Cunningham and the Cadillac engine was also used in export editions of Britain’s J2. Allard. Power output increased steadily: 190bhp in 1952 (by which time manual transmission was no longer offered), 210bhp in 1953 (when a 12-volt electric system was standardized), and 230bhp in 1954, the year when panoramic wrap-around windscreens and power-assisted steering became standard on the Cadillac for sale.

The expensive Cadillac Eldorado Brougham of 1957 (it cost over $13.000) was the first car to have air suspension (dropped after a few seasons) as standard equipment, while Cadillac, along with Lincoln, started the fashion for four headlamps, that later became universal in the USA. 1966 Cadillac cars featured GM’s perimeter-type chassis frame, a 340bhp 7-litre engine, variable-rate power steering, full air conditioning, electric door locks and seat controls, a time switch for the headlamps and a six-position steering wheel. Prices started at $4.650. In 1967 Cadillac set a new sales record of 213.161 cars, bettered in 1969 with 266.798/ They introduced a fwd car on Oldsmobile Toronado lines, the Fleetwood Cadillac Eldorado with torsion-bar ifs, self-levelling suspension, and front disc brakes, these last being applied to the more expensive Cadillac Fleetwoods with conventional drive, and to all the 1969 Cadillac range. Capacity of the Cadillac V8 engine was increased – to 7.735cc in 1968 and to 8.2 litres in 1970, but otherwise there were no major changes. In 1973 Cadillac were one of the few firms offering a nine-seater limousine: the Cadillac 75 with a wheelbase of 12ft 7½in and an overall length of 20ft 8in.
