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 few petrol alternatives 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 up to 50.4mpg, while CO2 emissions of 147g/km mean it sits in a reasonable Benefit-in-Kind (BiK) band for a diesel SUV. Adding an automatic gearbox increases fuel consumption to 46.3mpg and emissions to 160g/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 44.8mpg, dropping to 42.8mpg with an automatic gearbox. CO2 figures are 165 and 173g/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 up to 42.2mpg with a manual gearbox or 38.7mpg as an automatic, with 166-182g/km CO2 emissions also placing the CX-5 in high BiK bands. There's also a single 2.5-litre petrol range-topper but as it manages just 35mpg, we imagine this will remain a niche choice in the UK.

All Mazda CX-5 models will cost the standard rate each year in VED (road tax)

Insurance

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.

Servicing

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.

Warranty

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. The Toyota RAV4's warranty of up to 10 years is even more generous.
