Hi there!

First driven in 1885 by German mechanical engineer Karl Benz (1844-1929), this innovative vehicle was the first in the world designed and built stem to stern for mechanized transportation via an internal combustion engine.
Benz's auto boasted a tubular steel frame, electric coil ignition, rack and pinion steering, an evaporative cooling system, and differential rear-end gears. Its 1600-cc., ¾ horsepower engine topped out at 8 mph.
