From Karl Benz's first gasoline-powered car in 1885 to today's family sedan, cars of the future, and exotic Formula 1 racers, kids learn how the internal combustion engine works, and how transmissions and drive trains propel cars of all types. The profusely illustrated How It Works Books present brief histories of engineering development. Detail drawings show mechanical parts and cut-away illustrations show how the parts are assembled and work together. This book's lift-the-flap illustrations reveal successive layers of detail in automobile construction.
