After revealing pictures of the Chevrolet Beat production version last week, GM seems to have more surprises in store. At the Detroit Auto Show, General Motors revealed that its all-new Chevrolet Spark would go on sale in the United States by 2011 and would reach South Korea & Europe in early 2010. The Beat concept small car which was showcased at the New York Auto Show in 2007, has been selected to become a global car – The Spark. Sources at Chevrolet confirmed that the production car will make its world debut at March’s Geneva Motor Show. The five-door compact small car will be sold as a world car to replace the current Matiz.
