The 2019 Infiniti Q50 AWD 2.0L gets 24 MPG combined, placing it in the middle of the entry-level luxury sedan segment. It isn’t a hybrid focused on fuel efficiency, nor is it a high-performance model prioritizing power. Instead, it balances style, comfort, and all-weather capability with reasonable gas mileage. This Q50 appeals to buyers who like the Infiniti brand’s blend of luxury and sportiness, and who also want all-wheel drive for bad weather or added stability. They are willing to trade a few MPG for that extra assurance, but still expect respectable fuel economy for daily driving and longer trips.

City and highway performance

The EPA estimates for the 2019 Infiniti Q50 AWD with the 2.0L 4-cylinder engine are 22 MPG in the city and 28 MPG on the highway. The city number reflects stop-and-go traffic, where frequent acceleration and braking hurt fuel economy. The 28 MPG highway number is more achievable when cruising, showing the engine’s efficiency at a constant speed. The smooth-shifting 7-speed automatic transmission helps both city and highway performance, keeping the engine in its optimal power range for efficiency. Drivers who spend more time on the open road will likely see figures closer to, or even slightly above, the EPA’s highway estimate.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Infiniti Q50 AWD 2.0L at $2,400. This number is based on driving 15,000 miles per year, with 45% of those miles in the city and 55% on the highway, using national average fuel prices. Your actual fuel costs may change depending on your driving habits, local fuel prices, and driving conditions. Aggressive driving, frequent short trips, and idling can all increase fuel consumption and annual fuel expenses.

Real-world expectations

The EPA provides a standard estimate, but real-world fuel economy depends on several things. Expect lower mileage if you often drive fast, spend much time in traffic, or live in a hilly area. Well-maintained vehicles get better gas mileage, so following the manufacturer’s maintenance schedule is important. Tire pressure, air filter cleanliness, and spark plug condition can all affect fuel efficiency. Driving conservatively, with gentle acceleration and predicting traffic, will give you results closer to the EPA estimates.

How it compares

The 2019 Infiniti Q50 AWD 2.0L competes with other entry-level luxury sedans that offer all-wheel drive and similar engines. The Acura TLX 2.4L with all-wheel drive gets about 24 MPG combined, similar to the Q50, but the TLX has a less engaging driving experience. The BMW 330i xDrive, while a bit more expensive, delivers around 28 MPG combined, making it more fuel-efficient. The Mercedes-Benz C 300 4MATIC gets roughly 26 MPG combined, a slight improvement over the Q50. These comparisons are important for buyers who see fuel economy as a major factor in their decision. The Q50 isn’t the best in fuel efficiency, but it is competitive in its class, especially considering its price and features. You can also find Q50 MPG across all years to learn more.

Tips to maximize efficiency

Avoid fast acceleration and hard braking. The Q50’s 2.0L engine works well with a smooth and steady driving style. Anticipate traffic and keep a consistent speed when you can. Quick starts and stops waste gas.

Check your tire pressure often. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure at least once a month and make sure it matches the manufacturer’s recommended pressure, usually on a sticker inside the driver’s side door.

Reduce extra weight. Carrying extra weight in your car lowers fuel efficiency. Remove anything from your trunk or backseat that you don’t need. Even a little weight can add up and affect your MPG.

Use cruise control on the highway. Keeping a constant speed on the highway can improve fuel economy. Cruise control helps you maintain a consistent pace, leading to better mileage.

Limit idling. Idling wastes gas. If you’re stopped for more than a minute or two, turn off the engine. Modern engines restart quickly, so you won’t cause damage by turning the engine off and on.
