1906 National Model E

National built cars from 1900 to 1924 in Indianapolis, originally powered by electric motors. Electricity was phased out as a power source in 1906 when Arthur C. Newby became the company president. Newby was one of the four founders of the Indianapolis Motor Speedway where National won the 500-mile race in 1912 at an average speed of 78.72 mph. National still holds the record as the largest engine to ever win the Indy 500 with a four-cylinder engine that displaced 490 cubic inches!
