22 MPG combined isn’t going to win the 2023 Infiniti Q50 Red Sport 3.0L any fuel economy awards, but that’s not why anyone buys this car. This is a rear- or all-wheel-drive sport sedan with 400 horsepower. Fuel efficiency is likely near the bottom of the priority list for the buyer who values performance and sharp styling over practicality. The Q50 Red Sport is about driving enjoyment, and its fuel economy reflects that.

City and highway performance

The EPA estimates for the 2023 Infiniti Q50 Red Sport 3.0L are 20 MPG in the city and 26 MPG on the highway. The lower city figure is typical for turbocharged engines, which tend to be more sensitive to stop-and-go driving. The 26 MPG highway rating is respectable. It allows for comfortable road trips without excessive fuel stops, assuming you can resist the urge to use the twin-turbo V6’s considerable power.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2023 Infiniti Q50 Red Sport 3.0L will be approximately $2,650. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway, using national average fuel prices. Keep in mind that premium fuel is recommended for optimal performance in the Red Sport, but that higher octane premium fuel will contribute to that $2,650 figure.

Of course, your actual fuel costs will change depending on your driving habits, location, and fuel prices, but the EPA estimate provides a useful baseline for comparison.

Real-world expectations

While the EPA estimates offer a standardized benchmark, real-world fuel economy can vary significantly based on driving style and conditions. Aggressive acceleration, frequent hard braking, and sustained high speeds will all negatively impact fuel consumption. Conversely, a smoother, more conservative driving style, particularly on the highway, can potentially yield results closer to or even slightly above the EPA estimates.

However, since most Q50 Red Sport owners are buying the car for its performance capabilities, expecting to consistently achieve the EPA highway figure might be optimistic.

How it compares

Compared to its competitors in the sport sedan segment, the 2023 Infiniti Q50 Red Sport’s fuel economy is in the middle of the pack. For example, the BMW M340i xDrive, while offering similar levels of performance, manages around 25 MPG combined. The Audi S4 checks in at around 24 MPG combined. The Lexus IS 350 F Sport, with its naturally aspirated V6, achieves around 23 MPG combined.

The comparison matters in the character of the engine. The Lexus V6 doesn’t offer the same punch, and some buyers will accept a slight fuel-economy hit for the Q50’s rewarding turbo power. Before buying, checking Q50 MPG across all years will help you get a better idea of how the Red Sport’s efficiency has trended.

Tips to maximize efficiency

While the Q50 Red Sport prioritizes performance, there are still steps you can take to improve its fuel efficiency without sacrificing the driving experience.

Use the drive mode selector. Selecting the “Standard” or “Eco” mode will result in a less aggressive throttle response and more conservative transmission programming, and that can noticeably reduce fuel consumption, especially in city driving. It’s okay to use the “Sport” setting periodically, just be mindful that it comes at a fuel-economy cost.

Reduce idling time. Modern engines consume fuel even when stationary. Avoid unnecessary idling, such as warming the engine for extended periods. The Q50 Red Sport’s engine warms up quickly under normal driving conditions.

Ensure proper tire inflation. Under-inflated tires increase rolling resistance. That leads to reduced fuel economy. Regularly check your tire pressures and inflate them to the recommended levels, which can be found on the driver’s side doorjamb.

Maintain your vehicle properly. Regular maintenance, including air filter changes, spark plug replacements, and oil changes with the correct viscosity oil, ensures that the engine operates at peak efficiency. Consult your owner’s manual for the recommended maintenance schedule.

By implementing these strategies, Q50 Red Sport owners can make improvements in fuel efficiency without compromising the performance they love. Reviewing all Infiniti fuel economy data can help you see how Infiniti’s models compare beyond the Q50 Red Sport.
