1957 Aston Martin DBR2 news, pictures, and information

Racer
Chassis Num: DBR2/2
 
Aston Martin, in 1956, produced the DBR1/250 (2.5 litre) and DBR1/300 (3.0 litre) sports racing prototype for the World Racing Championship racing. For the 1957 Le Mans 25 Hour race, larger displacement engines were allowed. Two DBR2's were produced by Aston Martin with 3.7 liter engines. DBR2/1 DNF'ed at LeMans. The engine regulations were changed back to 3 liters which relegated the DBR2's to open events in England and the Americas. DBR2/1 won the 1958 US National Championship. The December 1959 appearance of DBR2/2 at the Nassau Speedweek driven by Stirling Moss was the last works sponsored race in an open Aston Martin.

DBR2/2 was driven by Stirling Moss to victory in the Governor's Trophy race in the Bahamas in 1958. It returned to the United Kingdom and was sold by Aston Martin in 1960. It was later owned by the late Victor Gauntlet, Chairman of the Aston Martin Company in the 1980s.

The DBR2 was designed with a tube frame derived from the 1955 Project Lagonda V-12 race car designed for long-distance racing. It had a dry weight of 1988 lbs and an Aston Martin designed 5-speed gearbox. In the front was a Porsche derived front suspension with a DeDion rear suspension setup. Top speed with the 4.2-liter engine was 197 MPH.
There were only two examples of the DBR2 constructed and both were a continuation of Aston Martin's racing efforts in Grand Prix competition, including the LeMans 24 Hour race. David Brown had purchased the company in 1946 and had made the necessary moves to guarantee Aston Martin would be a top contender. He had purchased the Lagonda rights including the designs of a six cylinder engine featuring two overhead camshafts. It was one of the last designs courtesy of the legendary W.O. Bentley and in the years to come, would be the foundation for Aston Martins success in racing.

The six cylinder engine was fast and provided the company with class victories, but it was never a contender for outright victory. The three-liter Aston Martin DB3S was introduced in 1953 and finally secured the company the podium finishes it was searching for, including the top three positions at Silverstone in 1954. A DBS3 finished in second place at the 24 Hours of LeMans in 1955. The cars would have many career highlights in the hands of factory drivers and by privateers.

The successor to the DB3S was the DBR1 and it was completely new, featuring a spaceframe type chassis designed by Ted Cutting, their chief designer. The design and construction resulted in a reduction in weight by 50 lbs when compared to the DBS3, all without compromising structural rigidity. The Lockheed disc brakes and suspension were similar to the DBS3. The engine placed in the first car was a 2.5-liter version of the twin-cam six while three-liter engines were used in a few of the other cars. The David Brown five-speed gearbox was mounted transversely in the car which allowed most of the weight to be properly distributed within the vehicle creating excellent balance. Ironically, the David Brown gearbox would later prove to be problematic.

The DBR1 made its racing debut at the 24 Hours of LeMans in 1956 where it was piloted by Tony Brooks and Reg Parnell. It was a refined sportscar that was still unable to keep pace with the more powerful V12 cars of Ferrari and Maserati, and retired prematurely from the race due to engine problems. This would be the DBR1's only racing appearance in 1956.

At the close of the 1956 season, John Wyer was named General Manager and Reg Parnell was given the duties of Racing Manager for the company. Under their guidance development would continue during the winter that involved many changes throughout the vehicle. The car was campaigned during the 1957 season and quickly proved it was a capable machine, scoring second place finishes in its first two races. A first place victory was in the near future but it required a modified version of the three-liter DB3S engine. Two more outright victories would follow, at Nurburgring 1000 KM and again at Spa. The three-liter engine was able to compete in sprint race, but on tracks with longer, fast straight stretches, more was needed. For this, a 3.7-liter DBR2 was constructed. In the hands of Roy Salvadori, it was able to earn a class victory at Silverstone. Unfortunately, it was not able to secure a victory at LeMans.

As the 1957 season came to a close, new regulations were placed on GP racing limiting the displacement size of engines to just three liters in the sports prototype category. For Aston Martin it meant their DBR2s with the 3.7-liter engine were ineligible to compete, but still used in non-championship races. The displacement limitation worked in their favor, as it made many of their competition obsolete, leaving just Ferrari to contend.

The 3.7-liter DBR2s scored several important victories in the hands of Moss. They were later sent to American privateers who used them in local events. The engines were later modified to 3.9-liters and then to 4.2. After two seasons, they were returned back to the factory and sold to privateers.

1999 European Grand Prix: The First and Last

However, on the 26th of September Herbert would show he still had some fight within and would actually be the one to earn a very important first for the team. Herbert's Formula One career would go through something of a renaissance af...[Read more...]

Following the news of Carroll Shelby's passing last month, Aston Martin was further saddened to learn of Roy Salvadori's death on Sunday (3 June) at the age of 90. The pair famously drove the Aston Martin DBR1 to victory at the 24 Hours of Le Mans in 1959 and to celebrate their contribution to the marque's heritage, Aston Martin is releasing images of the pair in race action. Salvadori, from Essex, Great Britain, made his Formula 1 debut in 1952 and went on to race in 50 Grands Prix, achievi...[Read more...]
1958 German Grand Prix: So Close Never Felt So Good!
On the 19th of July, at the 11th RAC British Grand Prix, Roy Salvadori would climb to the 3rd step on the podium. It would be the greatest result of his career in Formula One and it would be a most exuberant moment for the man from Dovercourt joining two other Brits on the podium of their home grand prix. However, it would be the race just two weeks later that would provide Salvadori with one of his greatest, and most disappointing, moments in Formula One. Salvadori's World Championship debut...[Read more...]
Aston Martin Racing Proves Winning Potential At Laguna Seca
Having started from pole position, Aston Martin Racing led the fiercely competitive GT category at Laguna Seca, California, until the first refuelling stops. Competing on the third round of the American Le Mans Series (ALMS), the team's #007 Vantage GTE had been on course for its best finish to date. However, it quickly became apparent that the time taken to refuel the Vantage GTE at pit stops – as a result of changes to ALMS fuelling restrictor regulations – would seriously harm the team's chan...[Read more...]
