The Volkswagen Jetta is an automobile produced by German automaker Volkswagen since 1979. Depending upon the model year, country of origin, and country of sale, it is sometimes known as the Atlantic, Bora, City Jetta, Fox, GLI, Sagitar, or Vento. It is essentially the saloon / sedan version of the compact car / small family car Volkswagen Golf, and spans five generations. The Jetta name was derived from the Jet stream, following Volkswagen's long tradition of naming cars for various winds. The Jetta body style was developed due in part to the Volkswagen marketing group's observation that the North American market leaned more towards sedans as opposed to the Golf's hatchback configuration. The new saloon variant was marketed as a more upscale car than its tailgated brethren, with nicer interior trim and a higher price. This proved to be a wise move on Volkswagen's part, as the Jetta became the best-selling European car in the United States, Canada, and Mexico. Over the years, the car has been offered in two and four-door sedan and five-door station wagon variants. As of 2005, over 6.6 million cars have been sold worldwide, with over 2.2 million alone sold in the United States. Since the original version in 1980, the car has grown in size and power with each successive generation.
