1954 Jaguar XK 120 Fixed Head Coupe
An official 132.6 mph run on Belgium’s Jabbeke motorway established the XK120 as the world’s fastest production car, validating both its name and Jaguar’s performance claims. Introduced at the October 1948 Earls Court Motor Show, the XK120 debuted as an open two-seater before the Fixed Head Coupe variant arrived in early 1951.
William Lyons’ flowing body design adapted successfully to the fully enclosed coupe configuration, retaining the car’s elegance and proportions.
Approximately 2,680 Fixed Head Coupe examples were built through the end of XK120 production in 1954, with the majority produced in left-hand drive for the American export market.
Power came from Jaguar’s 210-cubic-inch (3.4-liter) dual-overhead-cam inline-six with twin SU carburetors, producing 160 horsepower in standard form or 180 horsepower with the Special Equipment package. The aluminum-alloy cylinder head carried the twin overhead camshafts, while the crankshaft was supported by seven main bearings.
