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.
The DB5 is a tightly specified British grand tourer, designed by Touring, built by Aston Martin, and defined by disciplined evolution — not revolution.
The DB6 is a functional evolution — not a revolution — in Aston Martin’s grand touring line. Its Kammback tail and lengthened wheelbase directly address aerodynamic lift identified in wind tunnel testing. It retains the live-axle layout, rejecting the more complex de Dion prototype to prioritise production readiness. It is recognisable, stable, and rooted in continuity — not novelty.
The Maserati 3500 GT was Maserati's first successful Gran Turismo and series production vehicle, developed 1956–57 and launched in late 1957. Its bodywork was designed by Carrozzeria Touring following an introduction by Franco Cornacchia; Touring's 2+2, superleggera 'Dama Bianca' prototype was selected for series production after being shown alongside an Allemano prototype at the March 1957 Geneva Salon. It featured a front-mounted 3.5 L straight-six engine and rear-wheel drive, and 2,226 units were built between 1957 and 1964.
The Maserati 5000 GT is a rare, bespoke grand tourer commissioned by the Shah of Persia and built by Maserati in collaboration with Carrozzeria Touring, featuring a modified 4.9 L V8 engine derived from the 450S and mounted in a strengthened 3500 GT chassis. It was produced from 1959 to 1966, with 34 units made, primarily as two-seat coupés.
