While many modern vehicles easily get 20 MPG combined, the 2017 Infiniti Q70 AWD with the 3.7L V6 represents a conscious trade-off. This Q70 isn’t about saving fuel. It’s about offering a combination of luxury, all-weather capability, and engaging performance, a balance that appeals to a specific type of buyer willing to prioritize those attributes over outright efficiency. These owners value the Q70’s unique character and rewarding driving experience, understanding that its V6 engine requires more fuel.
City and highway performance
The EPA estimates the Q70 3.7 AWD at 18 MPG in the city and 24 MPG on the highway. The city figure reflects the engine’s need to work harder in stop-and-go traffic, where the all-wheel-drive system adds extra weight and drivetrain loss. The highway number is more respectable and shows the benefit of the seven-speed automatic transmission’s ability to cruise at lower RPMs. Even at 24 MPG on the open road, this Q70 is not class-leading in terms of fuel economy.
Annual fuel cost
The EPA calculates the annual fuel cost for the 2017 Infiniti Q70 3.7 AWD at $2,900. This figure is based on driving 15,000 miles per year and using the EPA’s assumed national average fuel prices at the time of testing. Your actual fuel costs will vary depending on your driving habits, fuel prices in your area, and the type of fuel you use. Premium fuel is recommended for optimal performance, further impacting the overall cost of ownership.
Real-world expectations
The EPA provides a standardized benchmark, but real-world fuel economy often deviates. Q70 owners who prioritize spirited driving and frequently engage the all-wheel-drive system can expect to see numbers closer to the city estimate, perhaps even slightly lower. On the other hand, those who primarily travel on highways and adopt a more conservative driving style could potentially achieve figures closer to, or even slightly exceeding, the 24 MPG highway rating. Ultimately, individual driving habits and conditions play a significant role in determining the actual fuel consumption of this vehicle. Check Q70 MPG across all years to see model year comparisons and driver reports.
How it compares
The 20 MPG combined rating places the Q70 3.7 AWD behind some of its competitors. For example, the Lexus GS 350 AWD achieves a combined 22 MPG, while the Acura TLX SH-AWD manages 24 MPG. The BMW 535i xDrive, known for its blend of performance and efficiency, gets around 23 MPG combined. Even the Genesis G80 3.8 AWD, a car similar in size, gets around 20 MPG in combined driving. The difference in MPG may seem small, but that difference can add up over time. Q70 buyers often accept this fuel economy trade-off for the Q70’s unique combination of styling and performance feel. Before making a purchase, review all Infiniti fuel economy data.
Tips to maximize efficiency
Avoid excessive idling, as this consumes fuel. The Q70’s engine is powerful, but it’s still burning fuel even when the vehicle is stationary. Minimize idling time, especially during colder months when warm-up periods are longer.
Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Check your tire pressure regularly and maintain the recommended levels, which can be found on a sticker inside the driver’s side doorjamb.
Reduce unnecessary weight in the vehicle. The 3.7L engine has plenty of power, but extra weight will impact fuel economy. Remove any items that aren’t essential. The less weight the Q70 has to haul around, the more efficiently it will operate.
Anticipate traffic flow and avoid aggressive acceleration and braking. Smooth, consistent driving is key to maximizing fuel economy. The Q70’s all-wheel-drive system can lead to a heavier foot on the accelerator; be mindful of your driving inputs.
Use cruise control on the highway. Maintaining a steady speed reduces unnecessary acceleration and deceleration, further contributing to improved fuel efficiency. This is especially beneficial on long trips, where slight improvements in MPG can have a noticeable impact.
