MPG, running costs & CO2 Rating

4.5 out of 5

Fuel economy is a real strong point of the Kadjar. The most economical engine can hit over 55mpg, meaning Renault's mid-size SUV stacks up well against the Skoda Karoq and Mazda CX-5, as well as the Nissan Qashqai on which it's based. 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

Most engines in the Kadjar range are relatively efficient and all feature in the same affordable Benefit-in-Kind (BiK) band for company-car drivers. The 1.5-litre dCi diesel steals the show with its 55.4-57.7mpg fuel economy. - but only when mated to the seven-speed automatic gearbox. Every version of the Kadjar costs the same £150 in annual road tax, but CO2 emissions are just 132g/km for the entry-level diesel model with a manual gearbox.

Opting for the 1.5-litre diesel engine in one of the higher trim levels with their larger alloy wheels does have an effect on economy, but perhaps by not as much as you might think. Even the thirstiest model, the GT Line with its 19-inch wheels, will still return almost over 57mpg and sits in a similar BiK tax bracket.

The 1.3-litre TCe 140 petrol returns solid fuel economy of 42.2-42.8mpg, 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.

Opt for the range-topping petrol engine, the TCe 160, and you'll officially see the same economy and emissions figures as the less powerful TCe 140 model. That equates to 42.8mpg, while CO2 emissions of 150g/km will net company car customers a high Benefit-in-Kind rating.

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.
