Aerodynamics, lightweight construction, power, and balance: RS models from Porsche are always the sharpest upgrade on this side of the racetrack.

The complete story of the RS is told with • more than 280 full-color photographs; • quotes from the engineers, designers, and other professionals who created and built the RS; and • a detailed data section with full technical specifications for every RS model. 256 pp | 280+ color photographs
