Hot on the heels of the revolutionary XK120 Jaguar’s revised XK140 sports car was a careful evolution of its predecessor one that set to smooth out rough edges of the XK120. Thanks to the glorious twin-overhead cam six-cylinder engine the XK120 offered near 120 mph performance and had earned its place as a world-beating sports car. But Jaguar was eager to rectify some of the complaints it heard from customers– such as a tendency to overheat in traffic a cramped cabin and sometimes unpredictable handling on rough roads. With the XK140 Jaguar introduced important refinements such as rack and pinion steering telescopic dampers and a larger radiator grille and revised cooling system. The body of the XK140 retained the 120’s svelte and feline curves but gained larger more protective bumpers and some additional exterior trim.Â
