MPG, running costs & CO2 Rating

3.5 out of 5

Fuel economy is a strong point of the Kadjar, although the frugal diesel engine is no longer available and that might limit the car’s appeal to some buyers. That engine could hit over 55mpg, while the remaining petrol returns up to 44mpg, which is on par with rivals. Renault's EasyLife package provides a tempting selection of benefits including affordable servicing, while insurance costs will be largely comparable to other cars in this class.

Renault Kadjar MPG & CO2

The 1.3-litre petrol engine in the Kadjar is relatively efficient but doesn’t have a particularly appealing Benefit-in-Kind (BiK) band for company-car drivers. Rivals with hybrid engines will be more suitable for business users. The 1.5-litre dCi diesel steals the show with its 55mpg fuel economy but it’s no longer available new. Every version of the Kadjar costs the same £150 in annual road tax.

The TCe 140 petrol returns solid fuel economy of 44.1mpg, but its CO2 emissions are relatively high, with the top-spec GT Line version putting out 152g/km placing it in the higher end of the BiK tax bandings.

Insurance group

The Kadjar’s insurance groups range from 17 for the entry-level 1.5-litre diesel, rising to group 19 for the top of the range diesel. Petrol-engined models range from group 19 to group 23. Those groups are generally on par with the Nissan Qashqai and even a regular family hatchback like the Ford Focus.


Renault’s warranty was lengthened to five years at the end of 2019. Mileage is limited to 100,000 miles during that time, and three years’ roadside assistance is included. The Kadjar's warranty is more generous than the three-year cover offered with the Nissan Qashqai.


Every version of the Renault Kadjar requires servicing after 18,000 miles or annually, whichever happens sooner. This could mean longer gaps between visits for high-mileage drivers, with most rival SUVs needing a service after 12,000 miles. Renault has introduced an optional EasyLife Pack that includes a three-year warranty, three years of servicing and three years of roadside assistance with prices starting at £299, so we expect the vast majority of owners to go for it. It’s worth noting that while this is a good deal, prices shoot up in the fourth year.
