A barn find in FH4, the DB4 GT Zagato has sadly not made its way to FH5. The beautiful body hides an improved I6, developing 318 PS (357 and 400 in later continuation models). Ercole Spada was the chief designer, tasked with making the DB4 lighter and smaller. Aluminium replaced steel wherever possible, and the bumpers disappeared, which gave the added benefit of a cleaner design. The GTZ never achieved the racing success of the DBR1. Aston Martin has collaborated with Zagato for limited-run models several times again, but as is often the case, the first one remains the best.
