23 MPG combined is an unremarkable figure for the 2022 Infiniti Q50 3.0L. It doesn’t make the Q50 a gas guzzler, but it places the car in the middle of the pack for fuel economy in the sport sedan segment. The Q50 buyer likely isn’t prioritizing Prius-level efficiency. This is a car purchased for its sleek styling, relatively accessible price point, and most importantly, its potent twin-turbo V6 engine. Fuel economy is a consideration, but rarely the deciding factor.

City and highway performance

The EPA estimates the Q50 3.0L will achieve 20 MPG in the city and 29 MPG on the highway. The difference between the two numbers indicates the engine is relatively efficient at steady speeds, but its fuel consumption increases noticeably in stop-and-go traffic. The automatic transmission’s seven gears help optimize fuel economy on the open road, keeping the engine in its most efficient operating range. In city driving, however, the frequent shifting and lower average speeds contribute to the drop in MPG. Aggressive driving habits will further reduce the city MPG, while disciplined highway driving can potentially exceed the EPA’s 29 MPG estimate.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2022 Infiniti Q50 3.0L is $2,500. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Individual fuel costs will vary depending on your driving habits and the prevailing fuel prices in your area. However, $2,500 provides a benchmark for estimating the potential expense of fueling the Q50 over the course of a year.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Q50 drivers who prioritize performance and enjoy the engine’s power output will likely see numbers closer to the low end of the EPA range, or even slightly below. Those who employ a more conservative driving style and spend a significant portion of their time on the highway may achieve results closer to, or even exceeding, the 29 MPG highway estimate. Factors such as traffic congestion, weather conditions, and vehicle maintenance can also impact fuel economy. It’s always best to track your own fuel consumption over time to get a more accurate picture of what to expect.

How it compares

The Q50’s fuel economy positions it competitively within its class, but it’s not a standout. The BMW 330i, for example, achieves a combined MPG of 28, offering a significant advantage in efficiency while still delivering a sporty driving experience. The Lexus IS 350, a naturally aspirated V6 competitor, manages a combined 23 MPG, matching the Q50’s figure, however some drivers may prefer its more reliable engine. The Acura TLX, specifically the base 2.0T model, boasts 25 MPG combined. For those prioritizing fuel efficiency, these alternatives offer advantages. Many choose the Q50 specifically for its VR30DDTT engine and the tuning potential it has, and this is what many performance-oriented customers are after.

Tips to maximize efficiency

One of the simplest ways to improve your Q50’s fuel economy is to adopt a smoother driving style. Avoid aggressive acceleration and hard braking, as these actions consume significantly more fuel. Instead, accelerate gradually and anticipate traffic conditions to maintain a more consistent speed.

Regular maintenance is critical for optimal fuel efficiency. Ensure your Q50’s tires are properly inflated, as underinflated tires increase rolling resistance and reduce MPG. Change your engine oil and filters according to the manufacturer’s recommendations. A well-maintained engine operates more efficiently and consumes less fuel.

Minimize unnecessary weight in your vehicle. Remove any items you don’t need to carry, as extra weight reduces fuel economy. The lighter the vehicle, the less energy it takes to accelerate and maintain speed.

Use cruise control on the highway to maintain a steady speed and minimize unnecessary acceleration. Cruise control can help regulate fuel consumption, particularly on long trips. Combine this with use of the Q50’s selectable drive modes, and Eco mode will help to improve gas mileage too.

Plan your trips strategically to minimize stop-and-go traffic. Use navigation apps to identify the quickest routes and avoid congested areas. Idling in traffic consumes fuel without covering any distance, so finding alternate routes can significantly improve your MPG.
