A.C. Bertelli was an Anglo-Italian racing driver, designer, mechanic, and businessman. He works as a consultant for companies such as Armstrong Siddeley, Coventry Simplex, and Rover. While working at Armstrong Siddeley he had met William Renwick, an engineer who had inherited a large amount of money. The two formed a company called Renwick & Bertelli Ltd in Birmingham in 1924 and produced a car called the R&B. It was powered by a four-cylinder 1.5-liter overhead camshaft engine installed in an Enfield-Alldays chassis. The car performed well and came to the attention of the Hon. John Benson whose mother Lady Charnwood had recently bought Bamford and Martin. In 1926, Bertelli and Renwick both joined the board of what became Aston Martin Motors Ltd., with the R&B providing the basis for a new range of cars.
The Aston Martin Company went through a succession of owners and in 1928 was acquired by Sidney Whitehouse who also bought Renwick & Bertelli and merged the companies. Bertelli remained with Aston Martin until 1938.
By the late 1930s, the company had turned its attention from producing racing and sports cars to building road-going cars. The Atom prototype was built in 1939 and had a steel spaceframe chassis designed by Claude Hill and clothed in four-door sedan bodywork. The car impressed gearbox manufacturer David Brown and convinced him to buy Aston Martin. The push-rod engine in the Atom was inadequate, so David Brown bought Lagonda, specifically for the W.O. Bentley-designed twin-cam six-cylinder engine. Soon, a small series of two-liter sports cars based on the Atom design had been built. Although commonly referred to as the DB1, they were officially called the 2-Liter Sports.
After World War II and at the New York Auto Show in April of 1950, Aston Martin introduced the six-cylinder DB2. The Lagonda straight-6 with dual SU carburetors produced just over 100 horsepower. It was placed within a shortened version of the tube-frame chassis designed by Hill for the 2-Litre Sports, with a fastback coupe body designed by Frank Freeley.
Three pre-production examples had been previewed even earlier, as they raced at the 24 Hours of Le Mans in 1949. One of those three became the development car for the production DB2. It had the Lagonda straight-6, while the other two were powered by four-cylinder 2-liter engines. The six-cylinder car, driven by Leslie Johnson, retired after six laps due to overheating caused by a broken water pump. One of the 2-liter cars was in 4th place when it crashed two hours short of the finish, fatally injuring driver Pierre Maréchal. The remaining car, driven by Arthur Jones and Nick Haines, finished 7th overall.
The following month, the six-cylinder car raced at the Spa 24-Hour race where Leslie Johnson and Charles Brackenbury finished 3rd. Nick Haines and Lance Macklin drove one of the 2-liter cars to a 5th place finish.
For the 1950 season, all three of these cars were fitted with the larger Lagonda engine. George Abecassis and Lance Macklin finished 5th at the 1950 LeMans race. Brackenbury and Reg Parnell finished in 6th, which won Aston Martin 1st and 2nd in the 3-liter class. A DB2 driven by Briggs Cunningham finished 2nd in class at the inaugural Sebring race meeting in December of 1950.
At the 1951 LeMans, Macklin and Eric Thompson finished 3rd overall, with Abecassis and Brian Shawe-Taylor 5th.
Production of the DB2 would continue until April of 1953 with 411 examples being built. At least 102 examples were Drophead Coupes. The first 49 examples had a different grille and larger large rectangular cooling vents in the front wings than the subsequent cars. The later cars had a one-piece grille with horizontal chrome slats while the early cars had a chrome-framed front grille in three separate parts.
Originally, the only body style available was a fixed-head coupe. It had a spare wheel located at the rear in a small compartment, and luggage space was located behind the front seats. In the front was a single-piece hood that was hinged at the front. The Drophead Coupe became available near the close of 1950.
The Vantage engine upgrade was introduced in April of 1950, and it came with larger SU carburetors and a higher compression ratio, boosting power to 125 bhp. Briggs Cunningham received the first DB2 Vantage, LML 50/21.
