Aston Martin DB4 (1958 to 1963)

The Aston Martin DB4 was introduced in 1958, signaling a new era for the company. The DB4 was an entirely new car, using a new platform as well as a new engine. The new 3.7L dual-overhead camshaft straight six engine was designed by Tadek Marek and produced 240hp. During the course of production, five different series of the DB4 were made, including a top of the line GT model. The differences between each series are largely cosmetic, yet small changes such as ride height adjustments and interior updates are notable among the series. The GT model featured a more powerful engine as well as more aerodynamic features. Nineteen of these GT cars were reworked and rebodied by Zagato to create the DB4 GT Zagato.
