22 MPG combined might raise eyebrows, but it’s important to consider the context: the 2019 Infiniti Q50 Red Sport AWD is not a commuter car focused on fuel efficiency. It’s a performance sedan that offers strong acceleration, confident handling, and a luxurious interior. Q50 Red Sport buyers prioritize power, style, and all-weather capability, accepting the associated fuel consumption.

City and highway performance

The EPA estimates 19 MPG in the city and 26 MPG on the highway. In urban environments, the Q50’s turbocharged 3.0-liter V6 is responsive, but stop-and-go traffic decreases fuel efficiency. The smooth-shifting 7-speed automatic transmission generally performs well, but its programming focuses on performance and it holds gears longer and downshifts to maintain boost. On the open road, the Q50’s fuel economy improves, and the 26 MPG highway rating showcases the engine’s ability to cruise at higher speeds with less demand on its power. However, aggressive driving decreases fuel economy. All-wheel drive also adds a small penalty compared to the rear-wheel drive model.

Annual fuel cost

The EPA projects an annual fuel cost of $2,650 for the 2019 Infiniti Q50 Red Sport AWD. This is based on 15,000 miles per year and national average fuel prices at the time of calculation. Individual fuel costs will vary based on driving habits, local fuel prices, and fuel type. While the Q50 Red Sport doesn’t require premium fuel, its performance is optimized for it, and lower-octane gasoline may slightly reduce power and efficiency. Considering the available performance, the fuel cost is justifiable for drivers who want the all-weather driving experience of the Q50 Red Sport.

Real-world expectations

EPA estimates offer a standardized benchmark, but real-world fuel economy can vary. Drivers who accelerate quickly or drive aggressively will likely see numbers closer to the city rating, or even lower. However, drivers who accelerate smoothly and maintain consistent highway speeds may achieve results closer to, or slightly above, the EPA’s highway rating. Ambient temperature, tire pressure, and the use of air conditioning also influence fuel consumption.

How it compares

The Infiniti Q50 Red Sport competes with the BMW 340i xDrive (25 MPG combined), the Mercedes-AMG C43 Sedan (22 MPG combined), and the Audi S4 (24 MPG combined). The C43 matches the Q50’s fuel economy, but the BMW and Audi offer slightly better numbers. However, the Infiniti offers a good value, with similar levels of performance and luxury at a potentially lower price. Shoppers considering vehicles across all years may also wish to examine Q50 MPG across all years. Ultimately, the decision comes down to individual priorities; those wanting the best gas mileage may prefer the BMW or Audi, while others may find the Q50’s performance, style, and value more appealing.

Tips to maximize efficiency

Anticipate traffic and drive smoothly. Avoid quick acceleration and hard braking, as these increase fuel consumption. The Q50’s torque makes it easy to accelerate without straining the engine.

Ensure tires are inflated properly. Underinflated tires increase rolling resistance, making the engine work harder, decreasing fuel economy. Check tire pressure regularly and inflate them to the recommended levels.

Minimize idling. If stopped for more than a minute or two, turn off the engine. Modern engines restart quickly and efficiently, and idling consumes fuel without moving.

Use cruise control on the highway to maintain a consistent speed and minimize throttle input. This can help you achieve or exceed the EPA’s highway fuel economy rating.

Consider using the Q50’s adjustable drive modes. In “Eco” mode, the throttle response is softened, and the transmission shifts earlier, increasing fuel efficiency. While this mode may slightly reduce performance, it can help conserve fuel during everyday driving.
