The exquisitely styled Bristol 403 aerodyne features the Superleggera method of body construction devised by the Carrozzeria Touring company that overlaid alloy panels on a lightweight tubular-steel framework, while the low-drag shape was achieved after hours of experimentation in the Bristol Aeroplane Company’s wind tunnel.

The 1971 cc six-cylinder engine was modified through the use of bigger valves and larger main bearings, which increased the power output to 100 horsepower as against 85 hp on the 401.
