THE ASTON MARTIN DB4 GT ZAGATO
L The Sanction 2 DB4 GT Zagatos An additional 4 “Sanction 2” DB4 GT Zagatos were authorised by Aston Martin in 1987, to complement the V8 Zagato project that Aston Martin had commissioned earlier. The “Sanction 2” project was entrusted to Richard Williams of RS Williams, with Zagato being approached to fabricate 4 new bodies and trim them. The project was duly completed and the 4 cars shown to the public in July 1991.Unused DB4 GT chassis numbers were given to each of the 4 cars, these being DB4GT/0192, 0196. 0197 and 0198. The Sanction 2 cars have benefited significantly from the experience, improved materials and general up- rating of the specification. Notable changes include an increase in engine capacity from 3670cc to 4212cc, new high lift camshafts and revised carburation using 50 DCO1/SP carburettors. The result increased power yet again from the nominal 314 BHP to a staggering 352 BHP. A back-to-back comparison between the original 19 Zagatos and the Sanction 2 cars can be found in Annex A. The Sanction 3 DB4 GT Zagato Following on from the commissioning of Zagato to produce body shells for the 4 Sanction 2 cars, Zagato actually made 6 body shells, leaving 2 unused. Richard Williams who had been entrusted with the production of the Sanction 2 cars, went back to Aston Martin and asked their permission to use the final 2 shells in yet another small batch of 2 cars. Known as Sanction 3 cars, they were allocated original DB4 chassis numbers. As such these cars are replicas in the true sense of the word. The mechanical specification was as Sanction 2.
