Aston Martin DB4
The DB4 is a grand tourer designed by Carrozzeria Touring, built at Newport Pagnell, and powered by a Tadek Marek–designed 3.7 L DOHC straight-6. It features servo-assisted disc brakes, independent front suspension with rack-and-pinion steering, and a live rear axle with Watt's linkage. Its design influenced later models including the DB4 GT Zagato and Lagonda Rapide. Technically distinct from both predecessor and successor, it was produced from 1958 to 1963.
