In the early 1970's, the Bristol 411 was claimed by some to be 'the fastest true 4-seater touring car' made. The series V Bristol 411 represented all that was 'grand' in British grand touring cars.
The 411 made its debut in 1969, however the Series V was introduced at the 1975 London Motor Show, the car being powered by a 6½-litre Chrysler engine (modified by Bristol), producing a gargantuan 418 Ib ft of torque which was enough to give it a top speed in excess of 140 mlph and to push it to 70 mph in a mere 9.5 seconds.
Not only did the 411 have tremendous performance, its 8.2:1 compression ratio meant that it could run on 2-star petrol to the order of approximately sixteen miles per gallon. Power was transmitted from the front-mounted engine, via a Torqueflite three-speed automatic transmission
(standard) and a hypoid-bevel final drive to the rear wheels.
was independent by wishbones, coil springs, an anti-roll bar
and adjustable telescopic dampers. Rear suspension
was by a live axle, long itudinal torsion bars
, trailing lower radius arms, upper torque arms, transverse Watts linkage and adjustable telescopic dampers.
An automatic levelling control was also used on the rear suspension
to keep the car stable. Braking was admirably taken care of by servo-assisted discs all round, giving a total swept area of 420 sq ins.
Power-assisted, recirculating-ball type steering
, along with the automatic transmission
and the servo brakes, made the 33 cwt 411 a lightweight to drive. The elegant two-door four-seater body housed a sumptuous interior, which featured leather reclining front seats, air-conditioning
(which we believe was an optional extra), electrically operated windows and an automatic speed control.
