The 2024 Infiniti QX50 2.0L delivers 26 MPG combined, a figure that places it in the compact luxury crossover segment, but it’s not a standout. This isn’t a vehicle designed to prioritize ultimate fuel efficiency; it’s built for drivers who want a premium experience with a distinctive style, advanced technology, and a punchy, unconventional engine. Consider young professionals, empty nesters, or small families who value curb appeal and a comfortable, connected driving experience more than squeezing every last mile out of a gallon. They’re willing to trade a few MPG for the QX50’s unique character and upscale features.

City and highway performance

The EPA estimates the 2024 QX50 at 23 MPG in the city and 29 MPG on the highway. The city number reflects urban driving, where the QX50’s turbocharged engine and eight-speed automatic transmission deliver responsive acceleration. On the open road, the 29 MPG figure is attainable during steady-state cruising because the transmission selects the optimal gear for efficiency. However, aggressive driving habits, especially frequent bursts of speed, will noticeably lower the highway MPG. The QX50’s 2.0L VC-Turbo is designed to deliver performance, and using that performance will impact your fuel bill.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2024 Infiniti QX50 2.0L is $2,250 per year. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and assumes the national average fuel price. Your actual fuel costs will vary depending on your driving habits, local fuel prices, and the type of fuel you use. For example, drivers with longer commutes or those who frequently encounter heavy traffic may find themselves exceeding the $2,250 estimate. It’s a useful benchmark, so consider your individual circumstances.

Real-world expectations

While the EPA estimates provide a valuable baseline, real-world MPG often differs. QX50 owners report combined MPG figures from the low 20s to the mid-20s, depending on driving style and environment. Drivers who spend most of their time in stop-and-go traffic tend to see numbers closer to the city estimate, while people with more highway miles may achieve figures slightly above the EPA’s highway rating. The QX50’s fuel economy is sensitive to aggressive acceleration and high speeds, so gentle driving habits are crucial for maximizing efficiency. Factors like tire pressure, vehicle maintenance, and the weight of cargo can also influence real-world MPG.

How it compares

The 2024 QX50’s fuel economy puts it in direct competition with other compact luxury crossovers. The Acura RDX, with its standard 2.0L turbo engine also delivers 28 MPG combined. The Lexus NX 350h hybrid achieves a much better 41 MPG combined, but at a potentially higher purchase price, making it the clear choice for less gas. The BMW X3 xDrive30i, with its 2.0L turbo, manages 25 MPG combined, essentially matching the QX50. These comparisons are critical for the QX50 buyer as they illuminate whether the Infiniti’s distinctive styling and technology are worth the slight trade-offs in fuel economy compared to its rivals. Some buyers may be willing to sacrifice 2 MPG for the QX50’s edgier design or its advanced ProPILOT Assist features.

Tips to maximize efficiency

One of the most effective ways to improve the QX50’s fuel economy is to adopt a smoother driving style. Avoid aggressive acceleration and braking, and maintain a steady speed whenever possible. The QX50’s VC-Turbo engine is responsive enough to provide adequate power without needing to constantly push it to its limits.

Regular maintenance is also important. Ensure that your tires are properly inflated to the recommended pressure, and follow the manufacturer’s recommended service schedule for oil changes and other routine maintenance. A well-maintained engine will run more efficiently and deliver better fuel economy.

Consider using the QX50’s drive mode selector to optimize fuel efficiency. The “Eco” mode adjusts throttle response and transmission settings to prioritize fuel economy over performance. While it may slightly reduce the vehicle’s responsiveness, it can help with fuel savings, especially during city driving.

Minimize unnecessary weight in the vehicle. Remove any heavy or bulky items that are not needed for your trip. Extra weight increases the engine’s workload and reduces fuel economy. This is especially important for those who frequently use their QX50 for cargo hauling.
