The Automobile — Julie L. Sinclair
Published by Capstone Press, 2004.
During the 1800s, the average person would not travel more than 1,200 miles in his or her lifetime. There were few roads, and stagecoaches and trains were the main ways of getting around. But in the 1870s, two German engineers named Nicolaus Otto and Gottlieb Daimler built an engine that ran on gasoline, and in 1885, Karl Benz built the first modern automobile. This simple introduction to the automobile explains how a car works, how cars became popular, and how cars are made today. |
