The 2017 Infiniti Q50S Red Sport AWD 3.0L 6-cyl gets 22 MPG combined. This isn’t going to win any hypermiling contests, but that’s not the main focus. This is a performance sedan with sharp handling, aggressive looks, and a strong engine. Owners aren’t typically cross-shopping with Prius drivers; they’re prioritizing driving thrills over less gas.

City and highway performance

The EPA estimates the Q50S Red Sport AWD will achieve 19 MPG in the city and 26 MPG on the highway. The difference between city and highway figures shows where this car performs best: stretching its legs on the open road. The turbocharged 3.0L V6 thrives at higher speeds, and the all-wheel-drive system provides confidence in various conditions. While 19 MPG around town isn’t terrible for a car with this much power, expect to see that number drop if you’re frequently driving hard. Highway figures are more attainable, especially if you resist the urge to constantly use the engine’s ample torque. But really, who can resist?

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2017 Infiniti Q50S Red Sport AWD will be $2,650. This figure is based on driving 15,000 miles per year and using current national average fuel prices for premium gasoline, which this engine requires for optimal performance. Your actual fuel costs may vary depending on your driving habits, the type of driving you do, and the price of gasoline in your area. If you predominantly drive in the city, or have a heavy foot, expect that annual cost to climb significantly. Owners who log primarily highway miles and drive conservatively might see a slightly lower figure.

Real-world expectations

While the EPA estimates offer a useful benchmark, real-world fuel economy for the Q50S Red Sport AWD often falls slightly below those numbers. Aggressive driving, stop-and-go traffic, and weather conditions all affect fuel economy. Owners report average combined fuel economy in the 19-23 MPG range. Some have seen closer to 26 MPG on long highway trips when cruising at a steady speed, but that requires effort and a willingness to dial back the fun. This car is designed to be enjoyed, and enjoying it typically involves using more fuel.

How it compares

Compared to its competitors, the Q50S Red Sport AWD is in the middle in terms of fuel economy. A comparable BMW 340i xDrive, for instance, is rated at 25 MPG combined, offering a slight edge in efficiency. The Mercedes-AMG C43 sedan, while delivering even more power, achieves a similar 22 MPG combined to the Infiniti. The Audi S4, with its more efficient engine, manages a combined 24 MPG. These differences matter to buyers who want a balance between performance and lower fuel costs. The Infiniti often wins on value: offering similar levels of performance and luxury at a more accessible price, making slightly lower fuel economy a worthwhile tradeoff for many.

Tips to maximize efficiency

The Q50S Red Sport AWD responds favorably to smooth, deliberate driving. Avoid harsh acceleration and braking, which consume more fuel and wear down components faster. Instead, gradually build speed and anticipate traffic flow to maintain momentum. This will help you stay out of the turbocharger’s boost zone, saving fuel.

Use the Infiniti Drive Mode Selector. The “Eco” mode dials back throttle response and adjusts shift points to prioritize fuel efficiency. While it won’t transform the Q50S into a hybrid, it can help squeeze out a few extra miles per gallon, especially during city driving.

Ensure that your tires are properly inflated. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly and inflate them to the recommended levels as noted on the sticker inside the driver’s side door jamb.

Reduce unnecessary weight. Carrying excessive cargo in the trunk adds extra load, making the engine work harder and consuming more fuel. Remove any items you don’t need to improve efficiency, especially on longer journeys.

Consider using cruise control on the highway. Maintaining a constant speed minimizes fluctuations in fuel consumption. Be mindful of hills and traffic conditions, and disengage cruise control when necessary to avoid excessive downshifting or acceleration.
