22 MPG combined isn’t going to win any awards, but the Q50 isn’t about maximizing fuel economy. It’s a compact luxury sedan engineered for drivers who prioritize a smooth and responsive driving experience, all-weather capability, and understated elegance. These buyers understand that the twin-turbocharged 3.0L V6 and standard all-wheel drive carry a cost at the pump, but they willingly accept this trade-off.

City and highway performance

The EPA estimates put the Q50 AWD at 19 MPG in the city and 27 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the engine works harder, and the all-wheel-drive system engages more frequently. The highway MPG acknowledges the Q50’s ability to cruise comfortably at higher speeds, where the engine can settle into a more efficient operating range. While 27 MPG is respectable for a V6 AWD sedan, drivers with longer commutes will see a greater benefit.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2022 Infiniti Q50 AWD is $2,650. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation, which drivers may find to be higher now. This cost emphasizes the need for prospective buyers to consider their average annual mileage, the type of driving they do (city vs. highway), and current fuel prices in their area to get a more realistic estimate of their yearly fuel expenses. The EPA uses figures at the time of the vehicle’s release to establish an objective standard and allow for fair comparisons between vehicles.

Real-world expectations

While the EPA figures provide a benchmark, real-world fuel economy for the Q50 AWD can vary considerably based on individual driving habits, road conditions, and even weather. Drivers who frequently accelerate aggressively or spend a lot of time in heavy traffic are unlikely to achieve the EPA estimates.

Those who adopt a more relaxed driving style and spend more time on the highway may see slightly better fuel economy. Tire pressure and regular maintenance also play a role in optimizing fuel efficiency. For those seeking further information, Q50 MPG across all years can be found on our site to review trends.

How it compares

The Q50’s fuel economy sits in a competitive but not class-leading spot within the luxury sedan segment. The Acura TLX SH-AWD with the turbo 2.0L manages about 24 MPG combined, making it more fuel-efficient. The BMW 330i xDrive also achieves around 28 MPG combined, a meaningful advantage. However, these vehicles often come with smaller engines and different driving dynamics. Buyers of the Q50 are often drawn to the V6 engine’s smooth power delivery, and that performance comes with a fuel consumption penalty.

Tips to maximize efficiency

Take advantage of the Q50’s drive mode selector. Opt for the “Eco” mode when you’re not in a hurry. This mode adjusts the engine and transmission settings to prioritize fuel efficiency over performance, resulting in a more relaxed throttle response and earlier upshifts.

Avoid aggressive acceleration and hard braking whenever possible. The twin-turbo V6 is eager to unleash its power, but gentle acceleration and smooth braking conserve fuel. Anticipate traffic flow and maintain a steady speed to minimize unnecessary fuel consumption.

Ensure your tires are properly inflated. Underinflated tires create more rolling resistance, which increases fuel consumption. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side doorjamb.

Keep your car properly maintained. Regular oil changes, air filter replacements, and spark plug maintenance all contribute to optimal engine performance and fuel efficiency. Following the manufacturer’s recommended maintenance schedule ensures that your Q50 is running at its best.
