Citroën has announced first details of mid-life revisions to its C1 city car.

The improvements include exterior styling, an upgraded interior, better fuel economy and lower CO2 emissions.

There are new wheels and trims whilst inside there are new upholstery and materials.

Citroën says the 1.0i 68hp petrol engine is now the lowest CO2 emitting petrol powered car currently on sale in the UK, with lowered CO2 emissions of just 106g/km (-2.7%), and a combined-cycle fuel consumption figure of 62.8mpg (+2.1%).

The new look C1 is set to go on sale early in 2009 when further details and prices will be announced.
