Citroen has introduced savings on diesel models throughout February and March, including up to £1,700 off the new C4 and £3,900 off all Xsara Picasso diesel models.

Diesel sales rose by almost 20% last year, meaning that a third of all new cars bought in the UK are now diesel powered.

These offers mean that the 92bhp Citroen C4 1.6HDi LX, which can return 60mpg, is now available for £10,995.

There are savings of £1,600 on all other diesel C4 models, while £1,100 off petrol variants allows the C4 range to start at £9,995.

Xsara Picasso buyers will save £3,900 on all diesel models (or £3,400 if they choose petrol), putting the price down to £10,495.

Citroen’s other MPVs also benefit from special diesel deals, with savings of up to £3,500 and £1,700 on C8 and Berlingo Multispace models respectively.

Buyers of superminis can save up to £1,300 off the C2 1.4HDi, up to £2,200 off all diesel C3 models and a £1,500 saving on all C3 Pluriel models.

Buyers choosing petrol are offered savings from £1,100 to £3,400 depending on model.
