The ABC was an American high wheeler automobile built by Amedee B. Cole in St. Louis, Missouri, USA from 1905 to 1910. Known as the Autobuggy from 1906 to 1908, it was billed as "the cheapest high-grade car in America", and was available with 18 hp (13 kW) two-cylinder and 30 hp (22 kW) four-cylinder engines, friction drive, and pneumatic or solid tires. The drive system used a cone and two bevel wheels, one for forward and the other for reverse. This allowed it to reach its 30 mph (48 km/h) top speed in either direction. A larger engine was fitted in 1908, and the wheelbase grew from 72 in (180 cm) to 90 in (230 cm). Its high ground clearance made it popular in rural areas.
