The Chevrolet Viva has not been previously mentioned publicly by GM but is believed to be a B-segment car to replace the much-loved (not!) Aveo. The Viva is expected in 2011 to challenge the Ford Fiesta and Honda Fit. GM's announcement indicated that the factory would be tooled up for volumes of 160,000 units a year. It seems unlikely that the little Chevy Spark will be able to hit those kinds of numbers in the mid-term, but a slightly larger car s much more probable.
