MPG, running costs & CO2 Rating

3.0 out of 5

Fiat would like you to consider the 500X as a larger, more family-friendly version of the Fiat 500 city car – with running costs to match. But official fuel consumption figures for the petrol engines are unremarkable. However, road tax should be fairly painless; petrol models cost the standard rate in VED (road tax), while the mild-hybrid has a slightly reduced tax bill.

Fiat 500X MPG & CO2

Our pick of the range is the 1.0-litre petrol. This 118bhp engine offers better performance than the old 1.6-litre, but as it's turbocharged it's also more efficient, returning up to 45.6mpg and emitting from around 142g/km.

The 148bhp engine with its standard-fit automatic gearbox cost more to buy when it was on sale, but isn’t too expensive to run with up to 44.1mpg possible. Fiat has now replaced this engine with a 128bhp version equipped with mild-hybrid assistance, which achieves up to 49.6mpg. However, this engine is bafflingly expensive compared to the 1.0-litre petrol, so we don’t think it’s worth choosing it. The Ford Puma mild-hybrid is slightly more efficient and much cheaper to buy.

Its 129g/km CO2 emissions mean it’ll be slightly better for company-car drivers, but its Benefit-in-Kind tax ranking is still nothing to write home about. If this is important to you, a Toyota Yaris Cross or Renault Captur E-Tech may be better options.

The 500X falls into insurance groups 10 to 19. This is competitive with rivals such as the Nissan Juke (groups 8-20) and Renault Captur (groups 10-16). Dolcevita versions start in group 13.

Warranty

Like the rest of the Fiat range, the 500X is covered by a three-year warranty, which includes unlimited mileage for the first two years, but is capped at 100,000 miles for the third year. This outstrips many rival brands that put a 60,000-mile limit on their cover. Drivers intending to keep their car for longer may find Hyundai’s five-year cover or Kia’s seven-year policy more appealing, however.

Servicing

There's now an 'Easy Care' package that allows you to pay for up to five services up front. The first three years' worth of servicing can be covered when you buy the car and costs around £400, and we have seen promotions that bring this down to £200. This covers all parts and labour, including an oil and filter change when appropriate.
