Unveiled at the October 1959 London Motor Show, the DB4GT was a shorter-wheelbase, lightweight, higher-performance development of the DB4: faired-in headlamps, a twin-plug 3,670 cc twin-cam straight-six with triple Weber carburettors producing around 302 bhp, and a kerb weight roughly 85 kg below the DB4. 75 Touring-bodied DB4GTs were built, including lightweight racing examples.
The DB4GT Zagato, unveiled at the October 1960 London Motor Show, clothed the GT chassis in Ercole Spada's lighter, more aerodynamic aluminium body with plain oval grille, faired headlamps, Borrani wire wheels and a smoothed, finless tail; 19 were built 1961–1963 (23 chassis numbers were set aside), and all 19 originals survive. Four originals (0191, 0193, 1 VEV/0182, 2 VEV/0183) were built to lightened DP209 racing specification.
Later factory-sanctioned continuations — four Sanction II (1988–1991) and two Sanction III cars — were built from unused chassis numbers. Combined DB4GT and Zagato volume is around 94 cars; examples regularly exceed £1m at auction.
The DB4GT Zagato is among the most revered of all 1960s GTs; the Touring GT is a seven-figure blue-chip in its own right.
