Aston Martin DB4 GT

2014-04-07 Read: 526x

One year after the DB4's debut, Aston Martin launched the DB4 GT competition version. Designed to break Ferrari's GT-racing stronghold, the DB4 GT was built for both the works teams and privateers. Outwardly, subtle changes distinguished the the GT from the standard DB4. Under the Touring styled body various modifications were carried through that really turned the DB4 into a racer.

Weight reduction was one of the objectives in the GT's design. Most weight was saved by the wheelbase reduction of just over 12 cm. For the body construction the 'Superleggera' principle of body panels fixed on a tubular frame was used. The alloy panels of the DB4 were replaced by 18 gauge magnesium aluminium alloy panels on the GT. Most distinguishable features of the GT were the large air scoops and the cowled front lights.

The DB4 was the first road going Aston Martin to be equipped with the all-alloy 3670 cc straight six engine, designed by Tadek Marek. In stock form the engine produced a decent 240 bhp, sufficient for road use but not enough to face the competition on the track. Power was increased to a factory claimed 302 bhp by fitting a twin-plug head, 3 Weber Carburetors instead of the two SUs and twin distributors.

As mentioned before, the DB4 GT made its public debut at the London Motorshow of 1959, but earlier in the year the prototype made an impressive competition debut in the hands of Stirling Moss in the International Trophy meeting at Silverstone. Moss took the victory in its class from a mediocre field. In the remainder of the season the DB4 GT proved fast and on pace with the less powerful long wheel base (LWB) Ferrari 250 GTs. Ferrari, however, were already working on a more powerful and short wheel base (SWB) version of the 250 GT.

Production started in all earnest in 1960 and at the end of the year many DB4 GTs were raced by privateers in Great Britain with considerable success. Although it was intended as a competition car, quite a few of the 74 DB4 GTs constructed were used as road cars. Unfortunately, it soon became evident that the much lighter 250 GT SWB had the run on the new Aston Martin. To gain competitiveness, a 'Lightweight' version was created, which featured additional alloy components and several holes drilled in non-vital chassis components.

More drastic measures were nevertheless needed to bring the DB4 GT up to 250 GT pace. Aston Martin commissioned Italian coachbuilder Zagato to design and construct an even lighter body. Zagato had earned quite a reputation with their lightweight bodies, mostly fitted on competition Abarths and Alfa Romeos. Lighter and more powerful than ever, the DB4 GT Zagato was still not able to beat the Ferraris. The final DB4 GT constructed was fitted with a Bertone styled body and was shown at the 1961 Geneva and Turin Motorshows. The passing of the DB4 GT in 1963 meant the end of the factory competition effort.

Although the DB4 GT was not the success Aston Martin hoped for, it holds a special place in Aston Martin history. The rare Zagato bodied version is considered by many as one of the best looking cars ever constructed. Many of the 74 DB4 GTs are still regularly used in a wide variety of events and have in recent gradually gained in value with the best examples now commanding seven-figure prices in most currencies.

Chassis: DB4GT/0110/R

This right-hand-drive DB4 GT was ordered new by an amateur British racer. He regularly campaigned the car in minor events throughout the country, including the 1966 Brighton Speed Trials. In recent years, the car has been meticulously restored and prepared for historic racing by Aston Engineering. It has since been campaigned in many of the major events with considerable success. Chassis 0110/R is seen here during the 2012 Goodwood Revival where it was driven by Joe Twyman and Romain Dumas in the RAC TT Celebration race.

Aston Martin DB4 GT is reborn (2016)

The trend of resurrecting ghostly automobile legends continues with Aston Martin, which announced Friday it's building a limited run of 25 more DB4 GTs. Originally built from 1959 to 1963, the DB4 GT was among the most powerful British cars of its era and a precursor to the modern supercar.

Just 75 DB4 GTs were built during the first run. The GT model was lighter and more powerful than the stock ...

Aston Martin DB4 buying guide (1958-1963)

It’s a tragedy that the Aston Martin DB4 – as well as its DB5 and DB6 successors – have now become so valuable that generally the only people buying them are collectors who have no intention of using them. Beautiful, superb to drive and genuinely usable grand tourers in the classic mould, it’s easy to see why the DB4 is so highly revered.

Aston Martin DB4GT & DB4GT Zagato

Aston Martin reached the pinnacle of sports-car racing in 1959. Helped by victory in that year’s Le Mans 24 Hours, it won the World Manufacturer’s Championship with the very special DBR 1/2. Of course, ordinary folk couldn’t buy a DBR 1/2, but they continually asked for faster and more specialized DB4s. Aston Martin responded between 1959 and 1963 with two distinctly different cars: the DB4GT and ...

Aston Martin DB4

The Aston Martin DB2 had been on sale five years before Aston Martin began contemplating a successor. Christened Aston Martin DB4, it was all-new, which helps explain why it took three years to be finalized, delaying its public launch until autumn 1958.

Key personalities behind the new Aston Martin DB model were general manager John Wyer (who would mastermind the birth of the Ford GT40 in the 196...

Evanta Aston Martin DB4 GT Zagato

Spend hundreds of thousands of pounds on a slice of classic automotive exotica and you can be sure of many things: rarity, raw simplicity and individuality. Unfortunately for many, lying on the hard shoulder of the M25, spanner in driving-glove-clad hand, is another unavoidable ingredient.
