The
Bristol 401 2-litre saloon was introduced in 1948 and
was the second car produced by the still very new company.
The main difference between this car and the earlier
400 was that the body panels were now all aluminium
and were fitted to a tubular steel framework that was
attached to the steel box section chassis. The car was
now slightly larger than its predecessor, and this resulted
in a more spacious interior that could now seat five
adults comfortably. The engine was the same six-cylinder
unit that was used in the 400. Some minor changes were
made during its production run, which included redesigned
bumpers and headlamps. The 401 was discontinued in September
1953 after the introduction of the 403 in May of the
same year, for which the engine had been redeveloped
to produce 100 bhp. This engine was also fitted to the
last few 401 models. Outwardly the 403 is very similar
in appearance to the 401 with only minor styling changes
distinguishing the two cars. The last few models of
the 403 had had an increase in engine power to 105 bhp
with production ending in 1955.
