The 2020 Infiniti Q50 AWD with the 3.0L V6 engine gets 22 MPG combined. While this isn’t the highest, it reflects the car’s design. The Q50 is chosen for its style, performance, and available all-weather capability, not just fuel efficiency. Drivers understand there’s a trade-off.

City and highway performance

The EPA estimates the 2020 Infiniti Q50 AWD 3.0L V6 will achieve 19 MPG in the city and 27 MPG on the highway. This difference highlights the car’s responsiveness. In stop-and-go conditions, the 3.0L V6 works harder, using more fuel. On the open road, where the engine can cruise efficiently, the Q50 achieves better numbers. Drivers who spend most of their time in urban environments will likely see MPG at the lower end of this range, while those with longer commutes will likely see figures closer to the EPA’s highway estimate.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2020 Infiniti Q50 AWD 3.0L V6 at $2,650. This is based on driving 15,000 miles per year, with a split between city and highway driving, and factoring in national average fuel prices. Individual costs will vary depending on driving habits, location, and gasoline prices. This assumes the use of premium fuel, which is recommended for optimal performance with this engine. For a broader context, see Q50 MPG across all years.

Real-world expectations

Real-world fuel economy often differs from EPA ratings. Aggressive driving, frequent acceleration, and heavy traffic can negatively impact MPG. Smooth acceleration, consistent speeds, and prioritizing highway miles can help achieve figures closer to or even slightly above the EPA estimates. Many owners report averaging around 20-24 MPG in mixed driving conditions. Remember that tire pressure and proper vehicle maintenance also affect fuel efficiency.

How it compares

The Q50 competes in a competitive segment. The BMW 330i xDrive, for example, has a combined EPA rating of 28 MPG, better than the Q50. The Acura TLX SH-AWD with the 2.0T engine offers a combined figure of 24 MPG. The Audi A4 quattro manages 27 MPG combined. The Mercedes-Benz C300 4MATIC comes in at a similar 26 MPG combined. Q50 buyers often cross-shop these vehicles, weighing performance and features against fuel economy. The Q50 offers a unique driving experience. For some, that’s worth the trade-off. Be sure to examine all Infiniti fuel economy data for a broader comparison.

Tips to maximize efficiency

The 3.0L V6 in the Q50 encourages spirited driving, but resisting the urge to constantly accelerate hard will improve your fuel economy. Gentle and progressive acceleration allows the engine to operate more efficiently, especially in city driving. Anticipate traffic flow and maintain a steady speed whenever possible.

Ensure your tires are properly inflated to the manufacturer’s recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and using more fuel. Check your tire pressure regularly, especially during changes in temperature, as this can affect pressure.

Reduce unnecessary weight in your vehicle. Extra cargo in the trunk or back seat adds to the overall weight of the car, requiring more energy to move it. Removing unnecessary items can incrementally improve fuel economy over time. This is especially true for heavier items like tools or sporting equipment.

Proper vehicle maintenance is critical for optimal fuel efficiency. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine is running smoothly and efficiently. Following the manufacturer’s recommended maintenance schedule can prevent minor issues from becoming major problems that negatively impact fuel economy.

Use cruise control on the highway to maintain a consistent speed and avoid unnecessary acceleration and deceleration. Cruise control helps the engine operate at its most efficient point, maximizing fuel economy during long highway drives. However, avoid using cruise control in hilly terrain, as the system may downshift frequently, negating some of the fuel-saving benefits.
