“This book is written with three distinct, if related, sections. The first of these gives a summarised history of Grand Prix racing in 1906-39 ; the second paints a broad picture of engineering development in this period by describing seventeen typical Grand Prix cars [including a Blower Bentley see p.182 et seq] with specification lists.... ; whilst the third section provides a contiuous historical narrative of technical change and relates engineering factors to road performance”. - from the Foreword.
The exceptional line drawings and cross-sectional views are by L. C. Cresswell, the finest engineering draughtsman of his age.
