Alfa Romeo Stelvio review - MPG, CO2 and running costs

Although the Stelvio doesn't feature any form of hybrid technology, Alfa's efforts to keep the extra pounds at bay has helped its premium SUV return decent fuel consumption figures and reasonably competitive levels of CO2.

Looking at fuel economy, the 187bhp diesel manages up to 47.9 mpg on the WLTP combined cycle, while there seems to be little penalty in going for the more powerful 207bhp oil-burner, as Alfa claims it will deliver an average of 47.1mpg - CO2 emissions are 156g/km and 162g/km, respectively. For comparison, the Audi Q5 40 TDI is capable of 44.8mpg, with CO2 emissions from 164g/km.

The petrols naturally fare less well, although we'd question how the 197bhp and 276bhp models both have the same claimed fuel economy figure of 33.6mpg. CO2 emissions start from 191g/km.

Unsurprisingly, the Quadrifoglio version with its 503bhp 2.9-litre V6 petrol engine will be the least frugal and the most costly to tax – but it should be comparable to a Porsche Macan GTS and the Mercedes-AMG GLC 63 S.

Insurance 

Both 197bhp petrol and 187bhp diesel models in Sprint trim sit in group 31 for insurance. Upgrade to the 207bhp diesel and you'll probably be looking at more expensive premiums as it sits in group 34. The 276bhp petrol version is a few groups higher; 36 in Veloce or 37 in Veloce Ti trim.

Depreciation

The Stelvio should hold onto around 48 per cent of its original list price after a typical three-year/36,000-mile ownership period, with the more powerful (and expensive) Quadrifoglio versions performing a touch better at around 52 per cent.
