The Aston Martin DBR2 was a sports racing car built in 1957 as a sibling to the Aston Martin DBR1, yet competing in a larger engine capacity group. Development The DBR2 was created from a short lived Lagonda project known as DP166 (DP for Development Project), This was a multi tube, back bone space frame chassis designed by Willy Watson. This was a progression from the DP115 'wide tubed ladder type' chassis which was similar to that used in the DB3S. Both the DP115 and the DP166 chassis were originally fitted with the failed Lagonda 4.5L V12 engine. All Three of the DP166 chassis made were leaning up against the wall of the Feltham racing department awaiting their fate, that was until the chief race car designer for Aston Martin at that time Ted Cutting was asked by John Wyer to build two race cars from two of the three chassis. The engines to be used were the new Tadek Marek designed 6 cylinder, 3.7 litre unit. He had just completed this engine for the forthcoming DB4. Ted Cutting was allocated four of the six prototype DB4 engines made, these to be used in the DBR2 cars. This was much to the dismay of Tadek Marek. When Ted Cutting got his hands on the newly designed DB4 engines, he made some fundamental changes to the oil delivery system before the unit was fitted into the production DB4s. In 1958 a 3000 cc engine capacity limit was placed on prototype cars competing in the World Sportscar Championship, so the DBR2s at 3.700 cc could no longer compete at championship events. Sir David Brown then had the idea to send both the DBR2s to the USA and to use them as a promotional tool for his new DB4. Both DBR2s were sent to the USA with Rex Woodgate and used to good effect. The all aluminium bodies for the DBR2 were also designed by Ted Cutting. This was a similar design to the one he later used on his Le Man winning Aston Martin DBR1. The DBR2 was slightly larger and more aerodynamic. These cars would be christened DBR2/1 and DBR2/2. Racing history DBR2/1 initially began competition at the 1957 24 Hours of Le Mans, where it unfortunately retired, this was due to a poorly performing carburation system, which in effect was a single carburetor for each cylinder, this problem was resolved
