MPG, running costs & CO2 Rating

4.0 out of 5

The SEAT Arona uses a thoroughly modern range of petrol and diesel engines, and with both the 1.0-litre petrol and 1.6-litre diesel engine producing excellent fuel economy figures, the lower starting price of the petrol models could be a deciding factor for most buyers.

SEAT Arona MPG & CO2

The Arona uses the newest, most fuel-efficient engines offered by the VW Group, with an entry level 1.0-litre petrol, a more powerful 1.5-litre petrol and a 1.6-litre diesel engine.

The entry-level 94bhp 1.0-litre petrol engine is claimed to return 49.6mpg when combined with the standard manual gearbox, with CO2 emissions of 129g/km placing it in a reasonable bracket for Benefit-in-Kind company-car tax.

A 148bhp 1.5-litre petrol engine is offered with the FR and FR Sport models. It uses cylinder-deactivation to effectively reduce its size when full power isn't required – when cruising steadily, for example. This can return up to 48.7mpg, with emissions of 130g/km of CO2 placing it in an affordable BiK band.

The 1.6-litre diesel engine is now only offered in 94bhp form, with the more powerful 113bhp version discontinued in late 2019. It manages up to 58.9mpg and emits 125g/km, but it’s in a higher BiK band than the petrols because of the extra tax levied on diesel models. Fitting a DSG automatic gearbox affects running costs slightly, with fuel economy dropping to 54.3mpg with a slight rise in CO2 emission to 135g/km.


Insurance group ratings for the Arona start from eight for the entry-level 1.0-litre petrol, stretching to group 17 for the sporty 1.5-litre petrol.


SEAT offers fixed-price servicing plans for all its cars, which can be taken out on new cars until three months after the date of purchase. Customers can pay just over £400 upfront to cover the first two years/20,000 miles of routine maintenance, or spread the cost over 18 monthly payments of around £23.


Although SEAT's three-year/60,000-mile warranty is competitive against Ford and Peugeot, it's far from the most impressive on the market, coming well short of the five-year/unlimited-mileage policy enjoyed by Hyundai customers or Kia’s seven-year/100,000-mile warranty. The MG ZS, meanwhile, comes with a seven-year/80,000-mile warranty.
