The Aston Martin DB6 Mark II is a grand tourer made by British car manufacturer Aston Martin from 1969 to 1971.
The car was first presented at the 1965 London Motor Show as a natural evolution of the DB5 from which the front part of the bodywork was entirely recovered, up to the door. The rear part of the cockpit with a new tail, was completely new. During the years of production, it underwent only one update in 1969; on this occasion various details were shared with the DBS which in the meantime had entered production and which since 1971 replaced it in the Aston Martin range. The new MkII had rear seats rearranged, larger wheels and tires with flared wheel arches to accommodate them better and, on request, AE Brico fuel injection system combined with the Vantage high compression cylinder head and power steering.
PERFORMANCE (standard specification)
- Speed in top at 1 ,OOO rpm: 26.1 mph, 34.8 km/h
- Max engine rpm: 6.000
- 282 b.h.p. at 5,500 r.p.m.
- Fuel consumption: 15 m/ imp gal, 12.5 m/ US gal
- Max speeds: 44 mph, 71 km/h in 1st gear: 74 mph, 119 km/h in 2nd gear; 106 mph. 170 km/h in 3rd 157 mph, 252 km/h 131 mph, 211 km/h in 4th gear; gear; in 5th gear
The "Vantage" engine with flow-tuned manifolds develops 325,b.h.p. at 5,750
The DB6 Mark II was announced on 21 August 1969 produced at the end of the construction period, this can be identified by distinct flares on front and rear wheel arches and sitting on wider 8.15 x 15 tyres with 1/2" deeper 6" wheels.
The DB6 Mark II shared many parts with the then-new DBS parts with the DBS presented in 1967, which was powered by a V8 engine. As a successor, the Aston Martin Vantage based on the DBS came onto the market in 1972 with the well-known six-cylinder engine, which was only built until 1973.Available as an optional extra for the Mark II was AE Brico electronic fuel-injection combined with the higher compression ratio cylinder head. The Mark II edition shared many parts with the then-new DBS. The front suspension is independent, equipped with double wishbones, coil springs, telescopic hydraulic shock absorbers and stabilizer bar. The Salisbury rigid -axle rear suspension with transverse Watt linkage, longitudinal connecting rods and stabilizer bar finally adopted Armstrong Selectaride 2-calibration adjustable lever shock absorbers. The braking system remained a 4-disc Girling dual-circuit servo -assisted.
Prince Charles, Prince of Wales (now King), owns a DB6 Volante MkII that has been converted to run on bioethanol. The car was given to him by his mother on his 21st birthday. There was also available the DB6 Volante version . It went out of production together with the DB6 after 140 examples, including 19 Vantage Volante and 38 of the MkII.
From a technical point of view almost nothing changed from the previous DB5 apart from the longer wheelbase; The 4.0-liter in-line 6-cylinder engine with three SU carburettors designed by Tadek Marek remained the same. In the basic version it produced 282 HP at 5,500 rpm; this power increased to about 325 hp (at 5750 rpm) in the sportier Vantage variant with higher compression ratio.
