The Bristol 404 and Bristol 405 are British luxury cars which were manufactured by the Bristol Aeroplane Company. The 404 was manufactured from 1953 to 1958, and the 405 from 1955 to 1958. The models were successors to the Bristol 403. The 404 was a two-seat coupé and the 405 was available as a four-seat, four-door saloon and as a four-seat, two-door drophead coupé.
Unlike previous or later Bristol models, there is considerable confusion in nomenclature when it comes to the Bristol 404 and 405. The 404 was a very short-wheelbase car introduced in 1953, whereas the longer 405 was introduced in 1955. The wheelbases are 8 ft for the 404 and 9 ft for the 405.
Design
The 405 itself was seen in two versions. The more common (265 of 308 built) is a four-door saloon built on the standard chassis of the previous Bristols, whilst the 405 drophead coupé or 405D (43 built) had a convertible body by Abbotts of Farnham. The body used aluminium panels over a steel and ash frame, mounted on a substantial horse-shoe shaped chassis.[2] Most cars built had a highly tuned (through advanced valve timing) version of the 2 litre six-cylinder engine called the 100C which developed 125 bhp as against the 105 bhp of the standard 100B 405 engine.
