Aston Martin DB6

Overview

Introduced at the 1965 Paris Motor Show, the DB6 was Aston Martin’s most comprehensive reworking of the DB series platform to date. While retaining the basic structure of the DB4 and DB5, the DB6 featured a longer wheelbase, a wider body, and substantially revised aerodynamics with a Kamm-style tail, Gurney flap, and larger front spoiler — all developed with genuine wind tunnel testing. The result was a car that was significantly more stable at high speed and more comfortable for long-distance continental touring than either predecessor.

The engine remained the 3,995 cc twin-overhead-cam straight-six developed by Tadek Marek, but with improved breathing and reliability. Standard cars used twin SU carburettors producing 282 hp; the Vantage option added three twin-choke Weber carburettors and raised output to 325 hp, giving a verified top speed of 257 km/h — genuinely competitive with the fastest cars of the era. The ZF five-speed gearbox was standard, with a Borg-Warner automatic available as an option.

The DB6 holds a special place in Aston Martin history as the last DB-series car to be produced under the ownership of Sir David Brown, who sold the company in 1972. Production at Newport Pagnell continued until 1971, making the DB6 the final expression of the original DB vision. With 1,753 produced — significantly more than the DB5 — it remains more accessible in the collector market, though equally prized for its driving qualities and historical significance.

Variant Comparison

What Makes It Stand Out

• Aerodynamic maturity: The DB6 was the first Aston Martin developed with genuine wind tunnel work — the Kamm tail and front spoiler meaningfully improved high-speed stability over the DB5.
• Superior passenger comfort: The extended wheelbase and repositioned seats made the DB6 a significantly better grand tourer for two passengers on long journeys than either the DB4 or DB5.
• Final David Brown-era car: The DB6 is the last of the line bearing David Brown’s personal imprint on the company and its products — a distinction that resonates deeply with Aston Martin historians.
• Vantage specification: The triple-Weber Vantage engine transforms the DB6 into a genuinely fast car even by modern sports car standards, with a characterful engine that rewards hard use.
• Greater production numbers: With nearly twice as many cars built as the DB5, the DB6 is more accessible in the collector market — yet retains the same hand-built Newport Pagnell quality.
• Royal patronage: HRH Prince Charles owned a DB6 Volante — a fact widely noted by the press and which contributed to the car’s elevated public profile in the United Kingdom.

Maintenance & Service in Azerbaijan

• Engine service: The Marek straight-six requires periodic valve clearance adjustment, carburettor balancing, and timing chain inspection; annual servicing is recommended for regularly driven cars.
• Weber carburettors (Vantage): Triple Webers demand careful synchronisation by an experienced classic car tuner; correct jetting for modern fuel compositions is important.
• Gearbox service: ZF 5-speed units are robust; use correct grade oil and inspect synchronisers every 50,000 km.
• Suspension and steering: Kingpin front suspension requires periodic greasing; steering rack play should be checked regularly for safe high-speed cruising.
• Body care: Like all aluminium-bodied Astons of this era, the DB6 is susceptible to corrosion at aluminium-to-steel interfaces; use recommended treatments and keep drainage channels clear.
• Fuel system: Upgrade fuel hoses to modern ethanol-compatible materials; the original rubber deteriorates with modern pump fuels and can cause fuel leaks.

Used DB6 Buying Checklist

• Original specification: Confirm whether the car is standard or Vantage specification; Vantage cars command a significant premium and should have the correct triple Weber carburettors in situ.
• Numbers matching: Verify chassis, engine, and body numbers correspond; unmatched numbers reduce value significantly even if the car is otherwise excellent.
• Aerodynamic components: Check that the front spoiler, Gurney flap, and roof vents (where fitted) are original items rather than reproductions.
• Body structure: Inspect the sill sections, inner wings, and floor for corrosion; the extended floorpan has more surface area than the DB5 and therefore more potential corrosion points.
• Gearbox operation: The ZF box should select all gears cleanly; crunchiness into second or third gear suggests worn synchronisers requiring rebuild.
• Volante hood: For Volante variants, test the hood mechanism fully and inspect the material for tears, shrinkage, or water ingress at the seals.

Frequently Asked Questions

Should You Buy an Aston Martin DB6?

The DB6 represents perhaps the most accessible entry point into the classic David Brown-era Aston Martin collection — more numerous than the DB5, yet equally hand-crafted and historically significant. For buyers who value the driving experience above pure provenance cachet, the DB6 is arguably the better car: more comfortable, more aerodynamically stable, and better suited to modern roads.

Acquisition requires the same diligence as any classic Aston Martin — numbers matching, full provenance, and specialist maintenance are non-negotiable. The Vantage specification and Volante body style command justified premiums. A well-maintained DB6 is not merely a collector car but a genuinely rewarding driving machine that connects its owner to the finest tradition of British grand touring.
