The incredibly fast and beautiful Jaguar XK120, priced at just £998 (£1,298 with tax) was launched at the Earls Court Motor Show in London on this day (27 October) 1948. The name was based on top speed that made it the fastest production car in the world.To convince the sceptics who refused to believe what was being claimed for the XK120, Jaguar took over a closed section of dual carriageway at Jabbeke in Belgium where, in front of the assembled press, a standard XK120 proceeded to clock 126 mph. With the windscreen removed 133 mph was achieved. Orders came flooding in and Jaguar quickly realised that the couple of hundred originally intended could not possibly meet demand. The waiting lists were lengthened still further after the XK's racing debut at Silverstone in a Production Sports Car race. The factory loaned three cars to well known drivers, Peter Walker, Leslie Johnson and Prince Bira of Siam. Bira was unlucky enough to have a puncture, but the others finished first and second.
