About the 1948 Jaguar XK120 Roadster
William Lyons' XK120 revolutionized sports car design when it debuted at the 1948 London Motor Show. Originally intended as a limited-production showcase for Jaguar's new twin-cam inline-six, overwhelming demand led to 7,631 roadsters being built over six years. The 120 mph top speed, unheard of for a production car under $4,000, came courtesy of the advanced 3.4-liter XK engine that would power Jaguars for decades. Early cars featured hand-formed aluminum bodies over ash frames, while later examples used steel construction. The roadster's pure lines and dramatic proportions established the template for British sports cars. Today, XK120 roadsters represent the most accessible entry into serious Jaguar collecting, with restored examples offering genuine 120-mph performance wrapped in timeless style. Racing provenance adds significant value, as many competed successfully in period.
