摘要

The last time the automotive industry in the United States experienced rapid technological change was more than a century ago. In 1900, the industry (whose primary competitor was the horse) comprised 40% steam-powered, 38% electric-powered, and 22% gasoline-powered vehicles. After the advent of mass-production, made famous by Henry Ford's 1908 Model T, the internal combustion engine rapidly became the dominant automotive technology, and by the 1930s competing technologies were all but extinct. Since then, the industry has followed a century-long trajectory of steady, incremental innovations that have gradually improved vehicle performance across a variety of metrics such as horsepower, fuel efficiency, emissions, and safety.
