The 2016 Infiniti Q50 AWD with the 3.0L V6 gets 22 MPG combined. This is not a class leading figure, but it’s an understandable compromise for drivers seeking a blend of performance, luxury, and all-weather confidence. This Q50 prioritizes a spirited driving experience with the added security of all-wheel drive rather than hybrid-like fuel efficiency. This balance will likely appeal to professionals who appreciate a well-appointed vehicle for daily commuting and weekend getaways, because they put refinement and quick power ahead of maximum fuel savings. These drivers will be paying a bit more at the pump, but the all-around driving experience justifies it.

City and highway performance

The EPA estimates show 19 MPG in the city and 27 MPG on the highway. The city figure reflects the reality of stop-and-go traffic for many Q50 owners. The highway number demonstrates the engine’s ability to deliver respectable efficiency when cruising at consistent speeds. The 3.0L V6 supplies good torque, which reduces the need for aggressive acceleration that would negatively impact fuel consumption. Also, the seven-speed automatic transmission optimizes efficiency by keeping the engine in its ideal power range.

Annual fuel cost

The EPA-estimated annual fuel cost for the 2016 Infiniti Q50 AWD 3.0L is $2,650. This calculation assumes 15,000 miles driven per year and factors in national average fuel prices. Of course, individual spending will vary depending on driving habits, local fuel costs, and the grade of fuel used. While premium fuel is recommended for optimal performance, many owners find that regular unleaded works fine, potentially reducing the annual fuel cost.

Real-world expectations

While EPA estimates provide a useful benchmark, real-world fuel economy often differs. Expect that aggressive driving, frequent short trips, and bad weather will reduce your MPG. Mindful driving, consistent highway speeds, and proper maintenance can help you achieve numbers closer to, or even slightly exceeding, the EPA estimates. Owners report that careful driving mode selection can produce a measurable impact on fuel consumption.

How it compares

The Q50’s fuel economy is near other vehicles in its class. The Lexus IS 350 AWD, for example, achieves a similar EPA combined rating of 22 MPG. The BMW 340i xDrive (25 MPG combined) is slightly better, but it comes with a higher price. The Acura TLX SH-AWD (25 MPG combined with the V6 engine) is in the same neighborhood, but its driving character is different. These comparisons are important for buyers who want a balance of luxury, performance, and all-weather capability, acknowledging that absolute fuel economy is not the highest priority.

Tips to maximize efficiency

Take advantage of the Infiniti Drive Mode Selector. Selecting “Eco” mode prioritizes fuel efficiency by adjusting throttle response and transmission mapping. That might reduce some of the car’s responsiveness, but it can improve MPG during daily commutes.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Regularly check your tire pressure and inflate them to the levels that are posted on the sticker inside the driver’s side door jamb.

Avoid idling your engine. Turn off the engine if you’re waiting for more than a minute. Modern engines restart quickly and efficiently, and prolonged idling wastes gas. This is important in colder climates where some drivers let their cars idle for extended periods.

Drive smoothly. Avoid rapid acceleration and hard braking because these consume more fuel. Anticipate traffic flow and keep a consistent speed whenever possible. Gentle acceleration will save fuel.

Make sure your Q50 is maintained properly. Regular oil changes, air filter replacements, and spark plug maintenance can contribute to optimal fuel economy. A well-maintained engine runs more efficiently.
