1958→1963 Aston Martin DB4
One of the all-time great Aston Martins is the DB4 grand tourer. When it was launched, Aston Martin's motorsport campaign had reached an all time high after winning the 1957 24 Hours of Le Mans with their purposeful DBR1 sportscar. Developments from the LeMans car were lent over to the DB4 including its all-alloy Inline-6.
Like the DB2 it replaced, the DB4 had a body-on-chassis design and it was graced with a lightweight aluminum bodywork from Carrozzeria Touring of Milan. Under the skin, the DB4 introduced more sporting engineering to Aston's touring range with its coil-on-wishbone front suspension, rack & pinion steering and 3.5 liter engine.
In regular road spec, the DB4 car went through five series of upgrades, while the Vantage and short-wheel-base DB4 GT were for track excursions. The most definitive version of the DB4 was the GT Zagato, which was lower, lighter and more beautiful than any other DB4.
