There are several cars that start with a "K." Among them is the Koenigsegg super car. The Kia car company, which is based in Korea, has the Kia K900 among its models. Ford makes the Ka, and Chevrolet makes the Kalos.
The Volkswagen Karmann-Ghia, which was produced from 1955 to 1974, allowed Volkswagen to expand its market share by breaking out of the economy car market. The car has since become a much-loved collector's item. The Chevrolet K car was the basis of many of Chevrolet models in the early 1980's but was used as a suffix to the actual model itself.
