Type 411 (Series 1)

Fitted 383 cu in. 6277cc engine installed with a Torqueflite 3 speed auto transmission. At first glance, the 411 body is very similar to the Type 410. Externally, the radiator grille is more trapezoidal than the 410's. The inner pair of driving lamps, housed in chromed shrouds, protrude from the radiator grille. Slimmer bumpers wrap round the body at front and rear. There is an air vent intersected by a short moulding strip on both rear wing flanks, linked by ducting to vents at the rear parcel shelf. Only one trim line is applied to the wing flanks. Door kick plates are narrower than on the 410. A wing mounted repeater flasher light is mounted on the top of the front wing flank. Bonnet badge is deleted in favour of a narrow Bristol nameplate on the grille and boot lid. The sculpting of the body around the outer headlamps is a particularly satisfying and attractive feature. Finally, the traditional twin-spoke Bluemel steering wheel is replaced by a smaller 3-spoke leather-trimmed wheel with a Bristol badge set into its central boss.


 Type 411 Series 2

Door locks and handles are semi recessed. Bumpers are marginally higher. A self-levelling suspension system was introduced. Odometer is also marked in Kph. Wheel rims are wider.


Type 411 Series 3

Body is completely restyled. New larger 6556cc 400c.i. engine introduced, but lower compression ratio (9.5:1) gives equivalent performance. Most noticeable changes in appearance are the front wings, bonnet and grille restyle. The wings are not notched and present 4 siamised 7 inch Headlamps, providing excellent illumination for night driving. A more powerful alternator is installed to supply more electrical current and to cope with the extra demand.

 Coach line replaces side trims; wider, higher kick-plate to protect door skins; indicator repeater lamps moved to front of wings. Raised wing crowns provide manoeuvring sightlines and air dam effect over bonnet surface at speed. At the rear, the exhaust is split into 4 tail pipes siamised to each side and finished with chrome trims. These are interesting because the pipe-ends are in fact dummies: the gases are vented downwards, some two inches further back, so as to spare the back garage wall a row of four unsightly soot-marks.


Type 411 Series 4

Power output is now down to 264 bhp at 4800 rpm, owing to still lower compression ratio of 8.2:1. New price in 1973 was 8973.


Type 411 Series 5

 Grille is of similar design to that used on the Series 4, but colour changed to matt black and centred coloured Pegasus emblem atop Bristol badge replaces the nameplate on the previous series. Inertia reel seat belts fitted as standard. Price new; 12,587.
