From the reviews: "This comprehensive work on the automotive chassis covers a wide range of topics at a high level--both mathematically and in terms of the state-of-the-art in engineering. The first volume treats wheels, suspensions, steering, brakes, and transmissions. ... Genta's extensive teaching experience at the Politecnico di Torino in Italy combined with Morello's experience as director of vehicle engineering at Fiat allow them to write authoritatively on this topic. ... Summing Up: Recommended. Upper-division undergraduate through professional automotive and mechanical engineering collections." (A. M. Strauss, Choice, Vol. 46 (11), July, 2009)
