Aston Martin DBR3 : ウィキペディア英語版 | Aston Martin DBR3 The Aston Martin DBR3 was a sports racing car built in 1958 as an alternative to the DBR1, using a different engine and front end setup. The car was very short lived and eventually converted into a DBR1. ==Design== The DBR3 was built from a DBR1 chassis and body but featured two major changes. First, the Lagonda based 2.9L Straight-6 was replaced by an engine based on that used in the newly released Aston Martin DB4 road car. While the DBR2 used this engine in its original 3.7L form, the DBR3 had the engine destroked to 3.0L (2990cc) in order to compete in the 3-Liter Sportscar category, just like DBR1. The second difference between the two was that instead of the standard front suspension from DBR1, DBR3 used a new wishbone suspension that was being developed for the DBR4 Formula One car at the same time. It was believed this setup would be superior to the one used on DBR1 and DBR2. Only one DBR3 chassis was built, known as DBR3/1.
