Owners of the 2019 Infiniti Q50 AWD with the 3.0L twin-turbo V6 average 22 MPG combined. It’s what you can expect if you want sharp styling, a potent engine, and all-weather confidence in a sedan that prioritizes driving engagement. Hyper-milers probably won’t buy this car; it’s for those who value spirited performance and a touch of luxury.

City and highway performance

The EPA estimates the 2019 Infiniti Q50 AWD at 19 MPG in the city and 27 MPG on the highway. The city numbers reflect the frequent stops of urban driving, where the V6 uses more gas. The 27 MPG highway figure is respectable, suggesting that the Q50 can deliver reasonable efficiency on longer cruises, assuming you don’t constantly accelerate.

Annual fuel cost

The EPA says the annual fuel cost for the 2019 Infiniti Q50 AWD is $2,650. This is based on driving 15,000 miles per year, with a mix of city and highway conditions, and using the national average fuel price when the test was performed. Your actual fuel costs will vary depending on how you drive, local fuel prices, and the type of fuel you use. Premium fuel is recommended, but the engine can run on regular fuel, though engine performance will suffer.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the Q50 AWD 3.0L can change a lot. Drivers who accelerate quickly are likely to see MPG figures closer to the low end, while those who accelerate smoothly and drive at consistent speeds may achieve results closer to, or even slightly exceeding, the EPA estimates. Terrain matters too. Driving in hilly areas will reduce fuel economy compared to flatter terrain. Don’t be surprised if your MPG is a little lower than the estimate, especially if you often use the engine’s power.

How it compares

The Q50’s fuel economy is about average for its class. The BMW 330i xDrive, gets a combined 28 MPG with its 2.0L turbocharged four-cylinder, a significant advantage. Those who want more power might find the BMW’s engine less desirable than the Q50’s V6. The Acura TLX SH-AWD with its 3.5L V6 offers 24 MPG combined. The Audi A4 allroad also offers 24 MPG combined, balancing practicality with fuel efficiency. Q50 buyers must consider if more efficient, but less powerful engines are worth the trade-off.

Tips to maximize efficiency

One of the easiest ways to improve fuel economy in the Q50 is to drive smoothly. Avoid accelerating quickly and braking hard, as these consume more fuel. Watch traffic and keep a steady speed when you can.

Check your tire pressure regularly. Underinflated tires increase rolling resistance, which reduces fuel economy. See the sticker on your driver’s side doorjamb for what your Q50’s tire pressure should be, and make sure your tires are properly inflated.

Don’t overuse accessories that put a load on the engine, like air conditioning and the defroster. While comfort is important, running these systems constantly, especially at their highest settings, will noticeably decrease fuel efficiency. A/C especially hurts fuel economy in shorter drives.

Consider taking a driving course. Proper driving has a big impact on fuel economy, and also reduces wear and tear on the car.

Keep your car well-maintained. Regular oil changes, air filter replacements, and spark plug replacements will ensure that your engine runs efficiently. A poorly maintained engine works harder and consumes more fuel. Browse all Infiniti fuel economy data and Q50 MPG across all years.
