Alfa Romeo Giulietta hatchback - MPG, running costs & CO2 (2010-2021)

The Alfa Romeo Giulietta diesel engines offer fuel economy of 50mpg but the petrol is noticeably thirstier. A Giulietta should return a reasonable chunk of its value when you go to sell it on after three years – around 42 to 45% of the original price, according to industry experts.

Alfa Romeo Giulietta MPG & CO2

The 118bhp 1.6-litre petrol engine that powers the Alfa Romeo Giulietta returns a slightly disappointing 38.2mpg and has CO2 emissions of 172g/km. This places the petrol-engined Giulietta in the highest Benefit-in-Kind (BiK) company car tax bracket, which is very steep for a car of this type.

To put those figures into context, a similarly powered Skoda Scala returns 47.8mpg and 129g/km of CO2, and you can achieve 51.4mpg from a Ford Focus EcoBoost engine. That means you could stretch to a highly specced car and still save money compared with buying a Giulietta.

Given the petrol-engined model’s high running costs it might be wiser to opt for one of the diesel versions of the Giulietta. The Super trim offers a 1.6-litre diesel with a choice of transmissions: either a six-speed manual or a six-speed ‘TCT’ twin-clutch semi-automatic, which both offer 50.4mpg.

The 2.0-litre diesel available on the Veloce trim is actually slightly more economical, returning 51.4mpg. It’s only offered with the automatic gearbox, and makes the car an expensive choice. Each diesel engine is one band lower than the petrol for company-car drivers.

No matter which engine you choose your Giulietta will cost £150 per year in VED (road tax).

Warranty

Alfa offers a three-year warranty on the Giulietta. There’s no mileage cap for the first two years of the policy, but a 100,000-mile limit is introduced for the third year. The paintwork is also guaranteed against defects for three years and there’s an eight-year warranty against rust.

In its class, this is similar to the Mercedes A-Class’ and BMW 1 Series’ warranties, while the Audi A3, Ford Focus and SEAT Leon come with slightly less generous three-year/60,000-mile policies.

Servicing

The Giulietta's main service falls due every two years or 36,000 miles, whichever comes first. It needs a minor service after one year or 18,000 miles – again, whichever comes first. You can opt for Alfa's 'Easy Care' service plan, which means you can pre-pay for your services, including all parts and labour. A three-year plan costs £500 for a petrol model and £550 for a diesel version.
