The Aston Martin DB3

L & # 39; car

The final evolution of the DB2 sports car, introduced in 1950, took the form of the DB2 / 4 Mark 3, whose production ended in 1959.

Although based on the DB2, the two-seater Aston Martin DB3, launched in 1951, was a pure racing variant of which, in 1953, ten cars had been built in total.

The first five pilots were assigned as work machines, while the remaining five were sold on the open market.

His race debut was the Tourist Trophy of 1951, during which he was forced to retire.

In 1952, he worked on the DB3, equipped with a 2.6-liter engine, finishing from second to fourth place at Silverstone against the tough competition from Ferrari and the Jaguar C-Type.

Overall, the DB3 sports car was not successful on the track since, in most cases, it was forced to retire for a variety of reasons.

The only great victory of the cars for the Aston Martin was the 1952 Goodwood 9 Hour race.

THE ENGINE

The first DB3 was powered by a 2.6-liter, DOHC, six in-line cylinders, mounted on the DB2 Vantage which developed 140 hp at 5200 rpm and produced a top speed of 131 miles per hour, with 0-60 kilometers per hour in 8.6 seconds.

With a compression of 8.2: 1, it was equipped with a five-speed David Brown manual transmission, with all-round drum brakes and an aluminum body on a tubular steel frame.

However, it was soon discovered that the 2.6-liter unit was inadequate and, in mid-1952, it was replaced by the larger 2.9-liter engine that produced 165 hp.

A small number of DB3 was also produced as a coupe variant.

The Aston Martin DB3S

L & # 39; car

Due to its weight, the DB3 proved to be non-competitive.

However, introduced in 1953, the two-seater DB3S sports car was the light version of the DB3, featuring a shorter wheelbase and a lighter chassis.

By the time production ended in 1956, a total of 31 DB3Ss had been built, of which 11 were jobs (like two fixed-head coupons and 9 open tops), the remaining 20 were sold to customers (like 3 fixed-head coupes) and 17 open tops).

The coupe variant was more aerodynamic and with lower drag than the open top, and thus produced a higher top speed.

Unfortunately, it tended to be less stable at high speeds, resulting from additional lifting.

In 1954, both working coupes were equipped with 225 hp engines, which were then modified with the addition of a compressor to develop another 15 hp.

However, instability caused both cars to crash in those years at Le Mans.

Returning to the open top variant, the DB3S took second place in the 24 Hours of Le Mans in 1955 and 1956, with Stirling Moss behind the wheel in this last race.

The DB3S was replaced by the enigmatic DBR1, which was victorious in Le Mans in 1959.

THE ENGINE

The 2.9-liter DOHC, six in-line cylinders, was now developing 210 hp at 6000 rpm and producing a top speed of 145 mph.

With a compression of 8.7: 1, it was equipped with a David Brown four-speed close-ratio manual transmission, three Weber dual choke carburettors, all-round disc brakes and its aluminum body produced an empty weight of 914 kg.

COMPETITION

At the head of the competition for the Aston Martin DB3S were the following sports cars: the Jaguar C-Type and the Ferrari 250 Testa Rossa
