The new Jaguar roadster unveiled at the March 1961 Geneva Auto Show looked more like a racing car than a production model, and it was, indeed, based on a racer - Jaguar's own Type D. Known as the Type E in Europe and called the XK-E in the United States, it could surpass 150 mph. Looks, performance and a price below $6,000 - this car had everything. Completely different in appearance from its XK predecessors but powered by a 3.8-liter version of the same six-cylinder engine, the XK-E roadster (and accompanying coupe) were the products of wind-tunnel research that shaped the radically aerodynamic form. Built around a central monocoque, the XK-E had front and rear tubular subframes to support the engine, and it had Jaguar's first four-wheel independent suspension.
