How much is it going to cost to run?

The Giulia is class competitive when it comes to fuelling and taxation costs, but servicing tends to be pricier than its rivals – which is worth considering if you’re a high-mileage driver. Since early 2021, the diesel models have been dropped, meaning you need to go elsewhere if you’re chasing maximum MPG.

MPG and CO2

The 2.0-litre, 200hp four-cylinder petrol has a claimed fuel consumption figure of 47.1mpg, but if you upgrade to the 280hp version, you see very slight drop to 46.3mpg. The CO2 output is 138 and 141g/km respectively.

You can rightfully expect the Giulia Quadrifoglio to cost more to run. Given its 2.9-litre twin-turbo V6, how could it be anything else? Don’t read too much into the claimed economy of 34.4mpg – we found the low 30s to be achievable, but 20-odd is much more typical in daily driving.

Servicing and maintenance

Alfa Romeo offers a number of service plans, depending what you want to spend on it up-front. The most comprehensive is what Alfa Romeo calls Easy Care, which covers all servicing and can be paid for when you buy the car or factor it into your monthly payments. Service Care is a similar package designed for Alfa Romeos older than a year, while Oil Care allows you to buy oil and filter services in advance.

Service plans are transferable between owners as long as the schedule is adhered to via Alfa Romeo dealers.


  • Alfa Romeo has not been a byword for reliability
  • Still, this is a new car from the ground up
  • Is that reassuring or alarming? Only time will tell…

There’s a big question mark here. Alfa Romeo’s reliability record is best described as ‘eventful’ but the Giulia is is proving dependable in service, including its engines. This isn’t always the case, which is a poor reputation with buyers, and not backed up by the marque’s non-appearance in the latest UK JD Power Vehicle Dependancy Survey.

The good news is there haven’t been any major recalls yet and Alfa Romeo fan forums have reported only a few niggling electronic issues. Still, it’d be worth watching this space.
