IMPROVED green credentials are on offer from the latest three-cylinder versions of the Citroen C3 which go on sale from this month.

And the even better news is that it won't cost buyers a penny more to be even more environmentally friendly.

The latest development work carried out by Citroen's engineers on the PureTech petrol engine have resulted in reductions of between three and seven g/km of CO and, despite the increased efficiency, prices of the latest models, which go into production this month, are unchanged.

For company car drivers, the lower CO emissions result in BIK tax band reductions of up to two per cent - reducing the monthly tax bill of a 40 per cent tax payer driving a Flair Plus PureTech 83 S&S manual model by over £140 in the 2021-22 period.

The developments include new batteries on versions equipped with a manual gearbox, with the entry-level PureTech 83 Stop and Start manual also receiving a new alternator to further optimise efficiency. In addition to this, all new C3 PureTech petrol models will also benefit from a fuel consumption meter as standard fitment ahead of the January 2021 regulations that sees their installation become mandatory.

Prices of the new C3 range, which is available in three trim levels, start from £16,280.
