Here's some happy news for Cummins. For the third year in succession, it has seen turnover in its Chinese business top $1 billion. According to the report, the US engine builder now makes 50 per cent of its money away from its domestic market - probably a good thing given the current state of the NAFTA Truck business - with India and Russia coming second and third to China in terms of value.

How does Cummins celebrate? It buys out partner Tata's stake in the Tata Holset JV. Does this mean Tata is looking elsewhere for engine assistance?

Maybe the fog has just lifted a bit in terms of the Iveco-Tata relationship.
