In 1994, General Motors de México first marketed the Corsa B as the Chevy, which would quickly replace Volkswagen's Sedán as the people's favorite. For 2004 (after the Corsa C was introduced), a Mexican designed and produced version of the hatchback and sedan, known as the Chevy C2, was released, which is also sold in Colombia. All Mexican previous versions were known as the Chevy, with the names Monza used on the sedan, and Swing (5-door) and Joy (3-door) for the hatchbacks. The latter 2004 and 2008 redesigns were simply named Chevy and Chevy Sedán. The Chevy was a favorite among taxicab drivers and one of the best-selling cars in the country. The Chevy ended production in late August 2011 at the Ramos Arizpe assembly plant. This move is because the Chevy´s sales have been dropping constantly since early 2010 and also because it doesn't meet with the new safety requirement rule in Mexico that forces it to have standard front airbags. The Chevy 5 hatchback was dropped after the 2010 model year, leaving only the four-door sedan and the 3-door hatchback, this last one being the most popular model. The Chevy is now discontinued, with only a short run of 2012 models after almost 18 years on the market. The successor for the 3-door & sedan, the Chevrolet Sonic will be built in Ramos Arizpe starting 2012 instead, while GM suddenly replaced the 5-door Chevy with the Chevrolet Spark.
