MPG, running costs & CO2 Rating

4.5 out of 5

A CX-5 is likely to be a first large SUV for many buyers, and if you’re graduating from a compact family hatchback, you probably won’t be bowled over by its running costs. When compared to those of other SUVs, though, the Mazda stacks up quite well.

Mazda CX-5 MPG & CO2

The CX-5 engine line-up consists mainly of diesels, with a petrol alternative that might appeal if you cover a low annual mileage.

The most economical engine in the range is the 148bhp 2.2-litre diesel. When teamed with a manual gearbox and front-wheel drive, it can return 47.9mpg, while CO2 emissions of 130g/km mean an affordable Benefit-in-Kind (BiK) rating for company-car users. Adding an automatic gearbox increases fuel consumption to 43.5mpg and emissions to 143g/km – with the BiK rising too.

If you want four-wheel-drive, you'll need the 182bhp version of the same engine. Thus equipped, the CX-5 returns 42.8mpg, dropping to 39.8mpg with an automatic gearbox. CO2 figures are 137 and 145g/km respectively.

If you cover fewer than 12,000 miles a year or so, a diesel is far less likely to save you money overall and you may be better served by the 2.0-litre 163bhp petrol engine. It can only be chosen with front-wheel drive, but is the least expensive engine in the range. Mazda claims it will return 38.2mpg with a manual gearbox, or 36.7mpg as an automatic, with 145-150g/km CO2 emissions for BiK ratings of 30-31%

All Mazda CX-5 models will cost £145 a year in VED (road tax).


Insurance group ratings range from 15 for the entry-level 2.0-litre petrol to group 21 for the 2.2-litre diesel at the top of the range. Spec for spec, the CX-5 is ranked a little higher than its Nissan Qashqai rival.


Mazda service intervals can vary depending on how your car is driven, but the maximum time and distance between scheduled service visits is 12 months or 12,500 miles, whichever occurs first. A service plan can be bought up-front to cover the first three years of servicing for your new CX-5 and monthly payment schemes are also available. Your local Mazda dealer will be happy to discuss the service option that fits best with your circumstances.


Every Mazda is supplied with a three-year/60,000 mile warranty, which includes a specific three-year paint warranty as well as a 12-year anti-perforation corrosion warranty. Mazda Roadside Assistance is provided throughout the warranty period.

Although this is equal to the cover provided by VW group companies such as Volkswagen, Audi, Skoda and SEAT, it’s less generous than the three-year/unlimited-mileage warranties of BMW and Mercedes. It also can’t come close to matching the impressive five-year/unlimited-mileage warranty provided by Hyundai – a brand whose Tucson SUV is a rival for the CX-5.
