The DB 2/4 Mark III (normally simply called DB Mark III, even at the time of its introduction) is a grand tourer sold by Aston Martin from 1957 until 1959. It was an evolution of the DB2/4 Mark II model it replaced, using an evolution of that car's Bentley-designed L (2922 cc/178 in³) Lagonda straight-6 engine, redesigned by Tadek Marek. It was succeeded by the Aston Martin DB4 in 1958. Changes included the front grille, that would become the shape of all future Aston Martin models (designed by Bert Thickpenny), a new instrument panel, and available Girling disc brakes. The hydraulically operated clutch was new as well, and an optional Laycock-de Normanville overdrive that was attached to the standard four-speed gearbox after the first 100 cars or even an automatic transmission were available. Worm-and-sector steering and a live axle rear end were carryovers. At the rear, the DB2/4 Mark II's tailfins (after the earliest few cars) were altered to use the rear lights from the Humber Hawk. The standard DBA engine model with twin SU carburettors produced 162 hp (121 kW), though an optional dual-exhaust system raised this to a reputed 178 hp (133 kW). Thus equipped, the car could reach 60 mph (97 km/h) in seconds and hit 120 mph (193 km/h). A mid-level DBD option with triple SU " carbs and dual exhaust produced 180 hp (134 kW), and was fitted to 47 cars. A high-output DBB engine with three twin-choke Weber 35 DCO 3 carburettors, special long duration camshafts, high compression :1 pistons and the dual-exhaust system was rated at 195 hp (145 kW) and ordered on just 10 cars. One car was fitted with the special DBC competition engine with a reputed 214 , this was fitted with racing camshafts, special connecting rods, very high compression pistons (possibly :1) & three twin-choke Weber 45 DCO 3 carburettors.
