Iveco, the commercial vehicle unit of Fiat Group, expects to see explosive growth in the Chinese bus market as China's population continues to migrate from rural areas to China's cities. Speaking at the launch of Iveco's new Stralis model range in Turin yesterday, Iveco's CEO, Michel de Lambert, pointed out that China is already the biggest national bus market in the world, with annual sales of 50,000 to 60,000 units.
