 testing, begun in February 1965, showed development was necessary to counteract a tendency toward aerodynamic lift [a result of the fastback styling] causing reduced rear-wheel traction at high speed. Final development phases relied upon DB5 chassis, suitably lengthened and titled MP 219, with rear lip-spoiler and abbreviated Kammback

A Kammback is a car body style that derives from the research of the German aerodynamicist Wunibald Kamm in the 1930s. The design calls for a body with smooth contours that continues to a tail that is abruptly cut off. This shape reduces the drag of the vehicle."Kammback" is an American term...

. The DB6 shares a large resemblance to its predecessor, the DB5; with the most noticeable differences being its wheelbase, side profile, split front and rear bumpers and rear panels incorporating the Kammback tail rear end. The tail, combined with the relocated rear-axle and the 3.75 inches (95.3 mm) lengthened wheelbase, provide more stability at high speed. Though fashionable-the rear-end Kamm-styled design was similar to the Ferrari 250

-it did not prove popular with conservative, tradition oriented Aston clientele when the DB6 was introduced. Performance was satisfactory: road-tests of the day observed top speed of the Vantage model between 145 mph to 148 mph, with intrepid and fearless John Bolster aboard a Vantage spec DB6 reaching a two-way average of 152 mph.

The DB6 continued with then high-tech Armstrong Selectaride cockpit-adjustable rear shock absorbers as available on the DB5. Other highlights include adopting front-door quarter windows, an oil-cooler air scoop low on the front valance, quarter-bumpers at each corner, revised tail-lamp clusters; additionally the spoiler with the luggage capacity affected overall proportions of the DB6, to an increased length approximately two inches.

Other notable changes:
  • Roof line raised by two inches improving headroom especially for rear seat passengers
  • Genuinely useful leg room for rear passengers
  • More steeply raked albeit taller windscreen
  • Split front and rear bumpers
  • Standard chrome wire wheels on bias-ply whitewall tyres [in USA market]

construction technique patented by coachbuilders/stylist Touring of Milan. For later DB6's construction, the more common body-on-platform technique was used; this was primarily due to the extended rear requiring a stronger and more rigid design using folding sheet metal frames. Surprisingly the modifications combined to add only seventeen pounds weight compared to the DB5.
