Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.

Fuel economy

Petrol engines 24.6 - 30.7 mpg
Diesel engines 39.2 - 47.9 mpg
  • All versions bar QV top 40mpg on paper
  • Diesels best for claimed fuel economy
  • Depreciation is proving to be heavy

If you want the most economical Stelvio, the rear-wheel drive 2.2-litre diesel with 190hp will be the one for you, claiming between 41.5mpg and 46.3mpg. The all-wheel drive version is only slightly behind at 39.2-44.1mpg. The 210hp diesel almost matches this, claiming between 39.2mpg and 43.5mpg. 

The petrols aren't quite as frugal. The 200hp model will manage 28-30.4mpg according to Alfa Romeo, while the 280hp model offers up 28.3-30.4mpg. In reality, you're unlikely to manage these claimed figures, so the diesel is your best option if you need to keep an eye on costs. 

As you may expect from a car with 510hp, running costs for the quickest Stelvio aren't going to be inconsequential. Depending on certain situations, three cylinders can switch off, unnoticed, to cut fuel consumption by 10%. The official claimed fuel economy is 28.8mpg, but if you use the engine even to half its full potential then expect that figure to drop markedly. 

Also, don't forget to factor in the huge, seriously sticky (and very expensive) Pirelli P Zero tyres and insurance that's bound to make a dent in your finances. 

All meet the latest Euro 6 emissions standard, so should have NOx (nitrogen oxides) well under control. All models come with stop-start technology to save fuel when stationary, helping to keep CO2 emissions at a reasonable level. The best performer here is the 190hp diesel, claiming 138g/km, while the AWD version emits 147g/km (the 210hp version matches this). Petrols are higher at 176g/km and 175g/km for the 200hp and 280hp models respectively. 

Is it reliable?

  • Alfa reliability isn't traditionally a strong point
  • But things have improved in recent years
  • Three-year, unlimited-mileage warranty

The Stelvio shares its platform with the Giulia, and while the company has seen its reliability improve in recent years, the Stelvio has still been the subject of three recalls so far.

This doesn’t mean you should expect the Stelvio to be unreliable, but you should be prepared for the possibility. Especially since Alfa Romeo has never built a vehicle of this type before, so doesn’t have any historic experience understanding the different stresses that SUVs have to withstand.

On early models we experience some niggles with the sat-nav system, while some quality issues in parts of the cabin could struggle to stand the test of time. 

You do get a three-year, unlimited mileage warranty for added peace of mind, though.
