The Volkswagen Jetta () is a compact car/small family car manufactured and marketed by Volkswagen since 1979. Positioned to fill a sedan niche slightly above the Golf hatchback, it has been marketed over seven generations, variously as the Atlantic, Vento, Bora, City Jetta, Jetta City, GLI, Jetta, Clasico, and Sagitar (in China). The Jetta has been offered in two- and four-door saloon/sedan and sometimes as five-door wagon/estate versions. Since the original 1980 version, the car has grown in size and power with each generation. By mid-2011, almost 10 million Jettas had been produced and sold around the world. As of April 2014, Volkswagen marketed over 14 million Jettas, becoming its top-selling model.
