The DB name came from the name David Brown (later Sir David Brown), an individual who had purchased the Aston Martin Company.
The DB4 series was built from 1958 through 1963. A total of 1040 vehicles and five series were produced during this time frame. The coachwork was performed by Touring of Milan, Italy. The body panels were hand made of aluminum mounted on a steel tube frame and featuring the Superleggera method of construction. Superleggera means super light.
Initially, the DB4 series used disc brakes made by Dunlop but later switched to the Girling made disc brakes. Each of the five series featured improvements, design modifications, and technological enhancements. All of the DB4s received their power from a Tadek Mereck designed, 3670 cc, six-cylinder, all aluminum engine. The 220-240 horsepower engine could propel the car to a top speed of around 140 mph and the go from zero to sixty in just 8.5 seconds. David Brown, the owner of Aston Martin, produced the overdrive transmission.
The standard DB4 body style was the Saloon version; however, the Vantage series could be ordered and featured higher horsepower ratings.
In 1959, Aston Martin introduced the DB4 GT series. This series featured a shorter wheelbase and higher output than the standard DB4 Saloon. Due to the shorter wheelbase there were no rear seats. The engine had three twin-choke Weber Carburetors and twin distributors increasing the output of the standard engine to 302 bhp. This extra horsepower increased the top speed to around 153 mph and the zero-to-sixty time of around six seconds.
Other distinguishable features of the GT series were the exposed, racing style, fuel filer caps located on the rear wings. Perspex headlamp covers adorned the front of the vehicles.
The GT series was produced from 1959 through 1963. During this time period, 75 models were produced. The Italian coachbuilder Zagato was tasked at producing the bodies of 19 of these vehicles.
In 1960 the Zagato bodied cars were introduced at the London Motor Show. These hand-built vehicles were built to outperform Ferrari's. The short wheelbase, light weight construction, 314 horsepower engine, and a top speed of 160 mph made them very competitive.
The DB4 Drophead Coupe was produced from 1961 through 1963. During this time frame, 70 examples were created. They were convertibles built on the DB4 Saloon body style using the same aluminum, Superleggera body construction. The standard six-cylinder 3670 cc engine was now producing 260 horsepower. Thirty-two of the convertibles received the Vantage specifications which increased the output of the engine. The overdrive transmission was also available as an option.
In the 1960's, the DB4 Drophead Coupe was used in the movie 'The Italian Job.'
During the 1980's, an Aston Martin specialist named Richard Williams produced the remaining DB4's using the assistance of the Aston Martin factory and unused chassis.
