One of the greatest drivers of his generation, Jim Hall is even better known as an innovator. From tiny Chaparral Cars in Midland, Texas emerged a series of vehicles that changed the face of racing. His high-winged Chaparral 2E Can-Am car and 2F World Sportscar Championship contender may be the most influential race vehicles of the 20th century. Today, every Formula 1 car uses net downforce, driver-adjustable wings, composite chassis, side-mounted radiators, semi-automatic gearboxes and advanced telemetry to optimize vehicle performance — all things Chaparral pioneered in the mid-1960s. Here he tells his story — his life, his cars, his relationship with Chevrolet, his partnership with Hap Sharp, his battles with sanctioning body bureaucracies — for the first time to award-winning author George Levy in this authorized biography.
