Drivers who choose the 2024 Infiniti Q50 Red Sport 3.0L 6-cyl accept 22 MPG combined. The focus isn’t on efficiency, but on the experience of a strong twin-turbo V6 in a sharply styled sedan. Buyers want satisfying performance and distinctive design, understanding there’s a fuel cost.
City and highway performance
The EPA estimates the Q50 Red Sport achieves 20 MPG in the city and 26 MPG on the highway. These figures reflect real-world driving conditions you might encounter in urban environments with frequent stops and starts, and sustained speeds on open roads. The difference between city and highway MPG shows the efficiency gains possible when the engine operates at a more consistent and optimal load, rather than constantly accelerating and decelerating. The Red Sport prioritizes responsiveness, and the turbocharged engine delivers instant power even when pushed hard around town. The seven-speed automatic transmission is also optimized for quick shifts and acceleration, which can impact fuel efficiency in stop-and-go traffic.
Annual fuel cost
The EPA estimates the annual fuel cost for operating a 2024 Infiniti Q50 Red Sport is $2,650. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price at the time of calculation. Actual fuel costs may vary depending on your driving habits, the type of fuel you use, and fluctuations in gas prices. Aggressive driving, prolonged idling, or using premium fuel can all increase your annual fuel expenses beyond the EPA estimate. The figure is a helpful benchmark, but not a guarantee.
Real-world expectations
EPA provides estimates, but real-world fuel economy often varies. Expect figures slightly lower than the official numbers, especially if you frequently drive hard or spend most of your time in congested urban areas. Drivers who prioritize fuel efficiency and practice smooth, consistent driving may achieve results closer to, or even slightly above, the EPA estimates. The Q50 Red Sport’s power encourages enthusiastic acceleration, which directly impacts fuel consumption. The fun comes at a price.
How it compares
The Q50 Red Sport’s fuel economy is in the middle of the sport sedan segment. The BMW M340i, with its turbocharged inline-six, manages around 26 MPG combined, offering similar performance with slightly better efficiency. The Audi S4 achieves around 24 MPG combined, balancing performance and fuel consumption. The Lexus IS 500 with its V8 engine gets around 20 MPG combined, showing that more power often means lower fuel economy. Buyers often weigh these fuel economy differences against each vehicle’s overall driving experience, features, and styling. If fuel efficiency is a top priority, comparing Q50 MPG across all years is an option before buying.
Tips to maximize efficiency
One often overlooked factor is tire pressure. Make sure your tires are inflated to the recommended pressure listed on the driver’s side doorjamb. Properly inflated tires reduce rolling resistance, improving fuel economy, and ensuring better handling and tire wear.
Gentle acceleration and braking can significantly impact fuel consumption, especially around town. Avoid aggressive starts and hard braking. Anticipate traffic flow and maintain a steady speed whenever possible. The Q50’s turbochargers are responsive, and excessive boost is unnecessary for smooth progress.
Consider using the Q50’s drive mode selector. “Eco” mode changes the engine and transmission to prioritize fuel efficiency over performance, making the throttle less sensitive and encouraging earlier upshifts. While it may slightly diminish the car’s sporty character, it can help save fuel during routine commutes.
Regular maintenance, including timely oil changes and air filter replacements, is essential for optimal engine performance and fuel efficiency. A clean air filter ensures proper airflow to the engine, while fresh oil reduces friction and wear. Follow the manufacturer’s recommended maintenance schedule for the best results, and explore all Infiniti fuel economy data.
