Book excerpt: Leading F1 journalist David Tremayne unravels the mysteries of modern Grand Prix car design. The authoritative, extensively illustrated text explains just how an F1 car works, and this revised and updated third edition includes new material about the rules changes introduced for the 2009 season. The philosophy and technology behind the chassis, engine, transmission, electronics, steering, suspension, brakes, tires and aerodynamics are analyzed, and the important question of how these parts and systems interact is explored. This is an absorbing insight into the secretive and technology-driven world of racing car design at its highest level.
