Honda will make stop-start standard on 1.2-litre petrol-engine versions of its Jazz (known as the Fit in Japan) small car in Europe for the first time. 

The Jazz is built in Swindon, England, and exported to mainland Europe.

Honda says that adding stop-start to the car will reduce CO2 emissions from 123g/km to 120g/km.

The Jazz is its best-selling model in Europe, accounting for over one in three sales. Total Jazz sales in Europe in 2011 were 56,500 as Honda saw overall sales slump 20% to 159,000 in the region.
