After Aston Martin had rejected proposals for a replacement for the DB5 from Touring of Milan, the decision was made to focus on their own development car, registered, 4 YMC. Wind tunnel testing, begun in February 1965, showed work was needed to counteract the cars tendency to lose rear-wheel traction at high speed. So the final development phases saw a DB5 chassis, suitably lengthened and titled MP 219, with a rear spoiler and abbreviated Kammback tail that Aston Martin had previously incorporated in sports racers. The decision was made to produce MP 219 as the Aston Martin DB6 although its de Dion rear axle was replaced with a live axle to reduce cost.
Introduced at the 1965 Motor Show, the Aston Martin DB6 was notable as the first model to be engineered following a factory move from Feltham to Newport Pagnell. From the front, the DB6 looked almost identical to the DB5; the greatest difference is in the rear panels which incorporate the Kammback. The tail, combined with the relocated rear axle and the 3.75-inch (95 mm) lengthened wheelbase, provide more stability at high speed. Though the rear-end Kamm-styled design was similar to the Ferrari 250, it did not prove popular with buyers when the DB6 was introduced.
Other recognition points include the return of front-door quarter windows, an oil-cooler air scoop low on the front end, quarter-bumpers at each corner and an overall length of the DB6 was increased by approximately two inches.
Other notable changes:
- Roof line raised by two inches
- More leg room for rear passengers
- More steeply raked windscreen
- Split front and rear bumpers
- Standard chrome wire wheels
- Optional power steering
- Optional air conditioning
- Standard ZF five speed manual unit and a Borg Warner or optional three speed automatic gearbox available at no extra cost
The DB6 is powered by the 3,995 cc twin overhead camshaft, straight, six engine Aston Martin engine designed by the legendary Tadek Marek. The engine, with its triple SU carb setup produces 282 bhp (210 kW; 286 PS) at 5,500 rpm; the Vantage engine option is quoted at 325 bhp (242 kW; 330 PS) against the 314 bhp (234 kW; 318 PS) of the DB5. Although the weight of the DB6 was approximately 17 lb (7.7 kg) heavier than its predecessor, the stability at high speed and comforts for passengers in this grand tourer more than offset the small loss in performance cause by the additional weight.

The DB6 Mark 2 was announced on 21 August 1969, identified by distinct flares on front and rear wheel arches and wider tyres. Available as an optional extra for the Mark 2 was AE Brico electronic fuel injection combined with the higher compression ratio cylinder head. The Mark 2 car shared many parts with the then-new DBS.
As with previous Aston Martin models, a high-power DB6 Vantage was built. It was equipped with three Weber carburetors and higher compression ratio cylinder head.
A convertible body style was also offered, per Aston tradition, called the DB6 Volante and first presented at the 1966 London Motor Show. It was the first time that Aston Martin used the Italian title "Volante" for a convertible, a name still used by the company today for its other convertible models. Early (1965-1966) DB6 Volantes had a "short chassis" body. Just 140 were built, including 29 high-output Vantage Volante versions.
A total of six DB6 Shooting-brakes were produced by British coachbuilder Harold Radford. The engine options (282 and 325 hp) were the same as for the DB6 Saloon.
