from classic to modern
CAR
The first Aston Martin sports car appeared in 1914.
In 1939, the Aston Martin Atom was introduced, a two-door, four-seater coupe, powered by a two-litre SOHC four-cylinder engine with twin Zenith carburettors.
In the early 1940s this unit was replaced by a 2-litre four-cylinder OHV engine with twin SU carburettors and a 7.25:1 compression ratio.
Linked to a four-speed semi-automatic gearbox, it developed 90 bhp at 4,750 rpm.
There was independent front suspension and leaf springs at the rear with Armstrong hydraulic shock absorbers. Production of the Atom ended in 1944.
In 1947, it was decided to design a new car but, at the time, the company was in financial difficulties and needed a cash injection.
The story goes that when industrialist David Brown drove the Atom in 1947, he was so impressed that he bought the Aston Martin company, having already acquired the Lagonda company.
Using the Atom as a base, David Brown felt that a convertible or convertible coupe variant, with a long and wide body style, would be the most appropriate format for production of the new car.
To withstand the additional stresses encountered when removing the roof section, the chassis would need additional reinforcement.
Although larger reciprocating twin-overhead six-cylinder engines were available to Lagonda, it was decided to retain the same 2-litre unit, as used in the Atom, and fitted with a four-speed, fully synchronized David Brown manual gearbox.
It had a steel body, with a very distinctive three-part grille, on a steel chassis, with a curb weight of 1,140 kg.
It used Girling 12-inch hydraulic drum brakes on 16-inch wheels, with worm and roller steering.
An intriguing design feature was the presence of a compartment in one of the front wings to store the spare wheel.
The new sports car was named the Two Liter Sports and was launched at the 1948 London Motor Show, when production would continue until the introduction of the DB2 in 1950, at which time the car would receive the alternative name Aston Martin DB1.
Unfortunately, the presence of a heavy two-seater cabriolet-style body and a modestly powered engine made the car underpowered, which was reflected in the fact that only 13 DB1s were built.
Furthermore, the chassis was only suitable for limited production, which meant that the car was expensive to produce and therefore not a profitable venture.
THE ASTON MARTIN SPA CONVERTIBLE
Prior to the launch of the DB1 sports car, it was decided that, as a means of extensively testing the chassis and engine, the car would be entered in the 1948 Belgian Spa 24-hour race.
The existing bodywork was replaced by a special version based on a small two-seater convertible.
As a result, the car won the race outright and was duly designated the Spa car.
After the race this car was rebuilt and displayed alongside the DB1 at the 1948 London Motor Show.
However, this single replica of the Spa, as it was known, failed to generate enough interest to warrant actual production, and it was subsequently displayed at the Dutch Motor Museum.
COMPETENCE
The market in which the Aston Martin was launched included the following sports cars: Triumph 2000, Cisitalia 202 SMM Spider Nuvolari, Bristol 401 and Maserati A6.
