Citroën has revealed an updated version of the C3 hatchback that will make its public debut at next month's Geneva Motor Show.

Although there are a few subtle cosmetic changes, perhaps the biggest news is the option of new three-cylinder petrol engines.

The VTi 68 and VTi 82 PureTech engines achieve between 62.8 and 65.7mpg, and CO2 emissions between 99 and 104g/km. A VTi 120 engine is also available with a manual or automatic gearbox.

The C3 will be available in the UK with four diesel engines - HDi 70, e-HDi 70, HDi 90 and e-HDi 115. The three powerplants with te-HDi technology offer CO2 emissions from 87 g/km.
