Chevrolet has unveiled its new city car challenger – the Spark.

Due to go on sale in the UK early next year, the new five-door model made its world debut at the Detroit show.

It will be built in South Korea and will also be offered in the US as Chevrolet aims to bring more fuel-efficient cars to America.

The firm also confirmed that its seven-seat Orlando MPV will become a production reality in 2010.
