"Campbell had not revised The Sports Car since 1959. The new third edition is thus most welcome in this fast-moving field. Ten years have brought great changes not only in engines, suspensions, brakes and transmissions, but also in performance characteristics and even fuels. Campbell brings all of the latest developments up to date. Highly informative and technical graphs, tables, and illustrations accompany each section of the book, making it an important addition to any library desiring a comprehensive automotive collection. Perhaps the most important section of Campbell's book is 'The Sports Car in the Future,' a major part of which describes the Wankel rotating combustion engine."
