25 MPG combined won’t win any fuel economy awards, but it’s an acceptable figure for the 2021 Infiniti QX50 AWD. This isn’t a hybrid or an economy car. It’s a compact luxury crossover designed for comfort, style, and all-weather confidence. Buyers drawn to the QX50 prioritize a premium experience over segment-leading efficiency and understand there’s a trade-off. They appreciate the comfortable interior, the sleek exterior design, and the availability of advanced technology features. These buyers aren’t hypermilers, but they aren’t oblivious to fuel costs either. They’re looking for a balanced package, and the QX50’s MPG fits within their acceptable range, especially when considering its upscale features.

City and highway performance

The EPA estimates the 2021 QX50 AWD at 22 MPG in the city and 28 MPG on the highway. These numbers reflect the car’s 2.0-liter turbocharged four-cylinder engine and its automatic (AV-S8) transmission. The city MPG aligns with typical stop-and-go driving, where the turbo engine works harder to get the QX50 moving from a standstill. The highway MPG is better because of more consistent speeds and less reliance on hard acceleration. Remember that the all-wheel drive system will also slightly reduce efficiency compared to a front-wheel drive model. To examine QX50 MPG across all years, you can compare older generations to find what works best for you.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Infiniti QX50 AWD at $2,300. This is calculated based on driving 15,000 miles per year and using national average fuel prices. Individual fuel costs will vary depending on local prices and driving habits, but this provides a standardized baseline for comparison. If you drive significantly more or less than 15,000 miles annually, you can adjust the estimate proportionally. Likewise, if fuel prices in your area are higher or lower than the national average, you can account for that difference as well.

Real-world expectations

While EPA estimates provide a useful benchmark, real-world fuel economy can vary. Factors like driving style, traffic conditions, and even tire pressure can impact MPG. Aggressive acceleration and frequent hard braking will decrease fuel efficiency, while smooth, consistent driving will improve it. Mountainous areas will also lead to lower MPG than flat terrain, and cold weather can negatively affect fuel economy as well. You might find the QX50’s real-world MPG to be slightly lower or higher than the EPA estimates, depending on your specific driving conditions. It’s always a good idea to track your own fuel consumption to get an accurate picture of your vehicle’s fuel efficiency.

How it compares

The Acura RDX SH-AWD, another popular compact luxury crossover, achieves a similar 23 MPG combined. The Lexus NX 300h AWD hybrid fares much better, boasting 31 MPG combined. The BMW X3 xDrive30i, with its sporty driving dynamics, returns around 24 MPG combined. This range presents buyers with a clear choice: Prioritize fuel efficiency with a hybrid like the NX, enjoy a sportier driving experience with the X3 and accept the slight MPG penalty, or find a balance of luxury and reasonable efficiency with the QX50 and RDX. The QX50’s buyers are often cross-shopping these vehicles, so the MPG differences become important in their decision-making process.

Tips to maximize efficiency

Use the QX50’s drive mode selector. Switching to “Eco” mode will adjust the throttle response and transmission mapping to prioritize fuel efficiency over performance. While this mode might feel less responsive, it can make a noticeable difference in MPG, especially during city driving.

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

Avoid unnecessary idling. If you’re stopped for more than a minute, turn off the engine. Modern cars are designed to restart quickly and efficiently, so idling is a wasteful practice that burns fuel without moving the car.

Minimize aerodynamic drag. Remove roof racks or cargo carriers when not in use, as they create drag and reduce fuel efficiency, especially at highway speeds. Even small changes to the vehicle’s aerodynamics can significantly impact MPG.

Plan your trips efficiently. Combine errands into a single trip to avoid multiple short drives. A cold engine is less efficient than a warm engine, so minimizing the number of cold starts will help improve your overall fuel economy.
