When
the Type 603 was first unveiled, it was available in two versions, 603 S
(Sports) or 603 E (Economy), both having the same body style, which
was once more designed in house. The ground clearance was somewhat better than
that of the 411, and the pillars at front and rear
slimmed to give unparalleled all-round vision. As in the 411, the cabin was
vented at the rear via two grilles in the rear parcel shelf. Unlike the 411,
however, these led into a void above the boot lid and were exhausted via a
series of holes just above the boot lid seal. To prevent ingress of water, the
holes were covered on the outside by a soft rubber flap that acted as a valve,
and was held in place with an aluminium strip. Another new feature was the
ventilation intake, inset into the bonnet just in front of the windscreen. The
cabin had become still more luxurious, with the provision of electric seats
and air conditioning as standard. Two levers mounted on the gearstick console
operated solenoids to release the boot lid and fuel filler flap, just behind
the left rear quarterlight.

When the S2 was introduced, the alternate performance specifications were dropped and the engine performance package standardized. One of the most obvious differences is that the rear cabin venting scheme reverted to the 411 formula, i.e. the two rear exhaust grilles were ducted down to the rear wing flanks where they issued in vents fitted with attractive matt black vanes.

The third series marked a more radical departure. Not only was there a new body treatment: two performance specifications were once more on offer, each now bearing the name of one of the Bristol Aeroplane Company products. The standard version, using the 360 cu. in. engine of the Series 2, was known as the Britannia, while the performance model, the Brigand, was equipped with a Rotomaster turbocharger — its presence being betrayed by the distinctive bonnet hump and the single exhaust.

Obviously this is a Brigand, with "Roz" from Britannia Airways in an early
publicity shot. What is not so obvious is that this early car does not have
the larger compound headlamp units, and has a larger radiator grille. Note new
alloy wheels and bulge in bonnet skin, also broad stainless steel strip insert
in bumpers.
Note the distinctive bulge in the bonnet (not properly closed in this photo.
This was necessary to clear the Rotomaster turbocharger. This later Brigand
has more refined bumpers with a narrower bright strip trim and showing showing
more black rubber than its predecessor.
The fourth series amply justifies not only the adoption of another famous Bristol Aeroplane Company name, but also a page of its own.
