I really enjoyed this book. It was easy to read and informative. The author clearly showed a great deal of familiarity with race cars and does a good job of laying out concepts without overcoming the reader with formulas or technical jargon. At the same time, he addresses some very cutting edge concepts such as the use of micro-vortex generators for drag reduction, and ground effects and exhaust powered ejectors for down force. There is certainly enough material covered to keep the most avid aerodynamicist interested and looking for more. Personally, I would love to see a follow up book published that goes into more technical detail, but I'm sure the author doesn't want to give up all of his secrets.
The only place where I did find the book lacking was in addressing vortex flow. Passenger automobiles are using turbulent air flow more often these days, primarily to reduce drag, yet none of the tricks you see commonly on Porsches or Corvettes, or even on every day sedans were addressed. Hopefully the author is saving this for his next book.
Overall I would definitely recommend that anyone interested in exotic cars, either as a spectator or operator, add this book to their collection.
