Ford has announced that the new C-Max and Grand C-Max will be more economical than their outgoing predecessors.

The new five and seven door models offer lower ownership costs according to Ford, based on improved residual values, lower insurance costs and CO₂ emissions and enhanced fuel economy.

Ford has calculated these savings at £800 a year compared to the current model.

Residual values increased over one year or 20,000 miles by up to 15 per cent, and by up to ten per cent for three years or 60,000 miles.

CAP Monitor set residual values at £9,475 for the five seat C-Max Zetec with a 1.6 litre petrol engine, and at £13,150 for the 2.0 litre TDCi Titanium model over 12 months. Ford expects similar figures for the seven seat Grand C-Max along with an improvement in Insurance group ratings.

The new MPVs come with a range of three petrol engines, including an all-new Ecoboost, direct-injection petrol engine.

The 1.6 litre, four cylinder powertrain has cut emissions and improved fuel economy by 20 per cent, unsurprisingly on the previous 2.0 litre version.

Alongside the petrol powertrain line-up sit two updated Duratorq diesel engines.

According to Ford, the new Grand C-Max with 1.6 litre TDCi offers class leading emissions of 129 g/km and a fuel economy of 57.7 mpg.

The new models will go on sale in October with the Ford C-Max priced at £16,745 and the Grand C-Max at £18,745 in the Zetec trim.
