22 MPG combined is what you can expect from the 2023 Infiniti Q50 AWD with its 3.0L twin-turbo V6. To be clear, this isn’t a Prius, and no one buys a Q50 expecting hybrid-like efficiency. It is a compact luxury sedan built for drivers who value a responsive engine and all-weather capability more than maximizing fuel savings. The Q50 buyer appreciates a bit of old-school feel and is willing to trade some MPGs for strong power.

City and highway performance

The EPA estimates the Q50 AWD at 19 MPG in the city. This reflects typical stop-and-go traffic, where the engine idles more and accelerates from stops often. The 27 MPG highway number is better, reflecting the benefits of maintaining a consistent speed. The Q50’s seven-speed automatic transmission helps achieve this by allowing the engine to run at a more efficient speed when cruising. While 27 MPG isn’t best-in-class, it’s respectable for highway commutes and road trips, where the Q50 really shines with its comfortable ride and easy passing. The MPG difference between city and highway driving is significant.

Annual fuel cost

The EPA says the annual fuel cost for the 2023 Infiniti Q50 AWD is $2,650. This is based on driving 15,000 miles annually, with 45% of those miles in the city and 55% on the highway. It also assumes gasoline is priced at the national average. Your actual fuel costs will vary depending on your driving, the type of gas you use, and where you live, since fuel prices change regionally.

Real-world expectations

EPA estimates are a good starting point, but real-world fuel economy is often different. Aggressive driving, excessive idling, and carrying extra weight in the car can all lower your MPG. On the other hand, a driver with a light foot who drives mostly on the highway might see numbers close to or even slightly better than the EPA’s 27 MPG estimate. Watch the Q50’s trip computer to better understand how you are using fuel. Driving style is very important.

How it compares

The Q50’s fuel economy is average when compared to its rivals. The BMW 330i xDrive, for example, gets a combined 28 MPG with its turbocharged four-cylinder. The Audi A4 quattro is also better than the Q50, with a combined fuel economy of 27 MPG. Even the Lexus IS 350 AWD, with its naturally aspirated V6, gets 22 MPG combined, matching the Q50 despite its more traditional engine design. This comparison matters because buyers in this segment often compare these vehicles, weighing performance, luxury, and fuel efficiency. For drivers who desire better MPG, these alternatives might be better picks, although they lack the strong power of the Q50’s V6.

Tips to maximize efficiency

Avoid hard acceleration and hard braking. The Q50’s responsive engine can be tempting, but being gentle with the accelerator will greatly improve fuel economy. Accelerating smoothly and anticipating traffic will help the automatic transmission stay in higher gears, which consumes less fuel.

Make sure your tires are inflated correctly. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check your tire pressure often and inflate them to the recommended PSI. You can find this information on a sticker inside the driver’s side doorjamb.

Reduce weight. Carrying extra cargo in the trunk adds weight to the vehicle, which hurts fuel economy. Remove any items you don’t need to lighten the load and improve efficiency. A lighter car needs less power, and therefore less fuel, to move.

Consider using cruise control on the highway. Maintaining a consistent speed with cruise control can help with fuel economy, especially on long trips. Pay attention to traffic and disengage cruise control when needed.

Stay on top of maintenance. Regular oil changes, air filter replacements, and spark plug maintenance help the engine run efficiently. A well-maintained engine consumes less fuel and performs the best.
