The diesel-powered three- and five-door Clios are priced from £12,690 on-the-road and are available to order now, Renault has announced.
Renault has cut emissions by 17g/km on the 115g/km dCi 86 model by improving the bodywork and refining the 1.5-litre engine for the eco range.
Fuel economy has been increased by 19 per cent to 76.3mpg – enough to travel the 456 miles from London to Lyon and back again according to Renault, which even claims there will be fuel to spare.
This has been achieved by reducing drag and introducing fuel-saving technology such as rolling resistance tyres.
Renault claims any exterior changes do not impact on driving pleasure or noise and the French marque was careful to avoid unsightly solutions such as rear lip spoilers and full disc wheel trims.
The new eco2 versions cost the same as the current dCi 86 models and benefit from zero vehicle exercise duty and, for commercial customers, a low benefit in kind rating.
The three-door version is available only in Extreme specification level and five-door model is offered in Expression trim and costs £13,290.
Standard specification on the Renault Clio eco² includes 4x20W RDS radio CD with fingertip remote control, front fog lights and electric front windows, while 15″ alloy wheels and fully integrated Carminat TomTom satellite navigation are optional.
