USER-choosers toying with the idea of a 4x4 could be swayed by research which shows the cost savings of opting for a diesel.

Findings from CAP Motor Research show that fleets opting for a diesel 4x4 can save more than £5,000 a year compared to a petrol equivalent.

Analysis of running costs by CAP has also shown that diesel 4x4s can be worth thousands of pounds more than petrol counterparts after just 12 months.

Mark Norman, managing editor of future residual value guide CAP Monitor, said: ‘The cost benefits of diesel in the heavy 4x4 market are unarguable, although this should not be assumed to translate across to other vehicle sectors.

‘Diesel fulfils the required characteristics for a large 4x4, favouring low-end torque over sports-type performance, as well as delivering lower fuel bills. With lower list prices than petrol variants, the diesel advantage looks assured.’
