2023 Alfa Romeo Giulia AWD: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 2023 Alfa Romeo Giulia AWD. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Fuel economy at a glance

These are the EPA's official ratings for the 2023 Alfa Romeo Giulia AWD. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 2023 Alfa Romeo Giulia AWD compares

The 2023 Alfa Romeo Giulia AWD returns 26 combined MPG. Cars in the Midsize Cars class for the same model year average 39.9 MPG, which puts this car behind the class average by about 35%.

The most efficient car in the Midsize Cars class for the 2023 model year is the Hyundai Ioniq 6 Long range RWD (18 inch Wheels) at 140 MPG. The bar chart below puts the Alfa Romeo Giulia AWD alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2023 model year (across all classes) returns 33.7 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2023 model year is on its own page.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for premium gasoline, which is $4.61/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 576.9 gallons (the car's annual consumption at the rated MPG).

Year-over-year MPG for the Alfa Romeo Giulia AWD

The EPA has rated the Alfa Romeo Giulia AWD across 10 model years, from 2017 Alfa Romeo Giulia AWD through 2026 Alfa Romeo Giulia AWD. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.

Combined MPG has stayed in roughly the same range across the run, hovering close to 26 MPG.

Specifications

The 2023 Alfa Romeo Giulia AWD runs a 2-liter 4-cylinder turbocharged engine paired with a automatic 8-spd, sending power through all-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.

Common questions about the 2023 Alfa Romeo Giulia AWD

Quick answers to the questions people most often search for when looking up the 2023 Alfa Romeo Giulia AWD.

• Is the 2023 Alfa Romeo Giulia AWD fuel efficient?

  Not particularly. The 2023 Alfa Romeo Giulia AWD returns 26 combined MPG, which trails the average car in the Midsize Cars class for the same model year by about 35%.
• What MPG does the 2023 Alfa Romeo Giulia AWD get?

  The EPA rates the 2023 Alfa Romeo Giulia AWD at 26 combined MPG, 23 MPG in city driving, and 31 MPG on the highway. Real-world numbers depend on your driving style, the weather, and how loaded the car is.
• How much does it cost to fuel a 2023 Alfa Romeo Giulia AWD per year?

  The EPA estimates an annual fuel cost of $2,650 for the 2023 Alfa Romeo Giulia AWD. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade.
• Does the 2023 Alfa Romeo Giulia AWD require premium gas?

  Yes. The EPA lists the 2023 Alfa Romeo Giulia AWD as requiring premium gasoline. Running it on regular can reduce performance and may affect engine warranties, so it is not a recommended way to save at the pump.
• Has the Alfa Romeo Giulia AWD become more fuel efficient over time?

  Combined MPG has stayed close to flat across the run. Both the earliest (2017 Alfa Romeo Giulia AWD, 26 MPG) and most recent (2026 Alfa Romeo Giulia AWD, 26 MPG) versions sit in the same range.
• How much CO₂ does the 2023 Alfa Romeo Giulia AWD emit?

  Tailpipe CO₂ emissions are 348 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 5,220 kilograms of CO₂.
• What is the difference between the city and highway MPG of the 2023 Alfa Romeo Giulia AWD?

  City driving returns 23 MPG and highway driving returns 31 MPG, a gap of 8 MPG. A spread that wide is typical of cars with conventional automatic or manual transmissions, where stop-start city traffic eats more fuel than a steady highway cruise.
• What engine is in the 2023 Alfa Romeo Giulia AWD?

  The 2023 Alfa Romeo Giulia AWD has a 2-liter 4-cylinder turbocharged engine (EPA description: SIDI). Smaller turbocharged engines like this one tend to deliver bigger-engine power on demand while keeping fuel economy closer to a non-turbo version of the same displacement.
• What transmission and drivetrain does the 2023 Alfa Romeo Giulia AWD have?

  The 2023 Alfa Romeo Giulia AWD comes with a automatic 8-spd transmission and all-wheel drive. All-wheel-drive variants typically read 1 to 3 MPG lower than the front-wheel-drive equivalent of the same engine, since the extra hardware adds weight and parasitic loss.
• How does the 2023 Alfa Romeo Giulia AWD compare to the best car in its class?

  The most efficient car in the Midsize Cars class for the 2023 model year is the Hyundai Ioniq 6 Long range RWD (18 inch Wheels) at 140 combined MPG. The Alfa Romeo Giulia AWD returns 26 MPG, a gap of 114 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
