30 MPG combined is a respectable figure for the 2017 Infiniti Q70 Hybrid, a car that prioritizes a smooth, refined driving experience over outright efficiency. While some hybrids loudly advertise their frugality, the Q70 Hybrid quietly offers a fuel-efficient alternative for buyers who value luxury and performance as much as they do economy.

City and highway performance

The Q70 Hybrid achieves an EPA-estimated 28 MPG in the city and 33 MPG on the highway. This split reflects the inherent advantage of hybrid powertrains in urban environments where stop-and-go traffic allows the electric motor to contribute more significantly. The electric motor assists the 3.5L V6 engine, reducing the need for the gasoline engine to work as hard during acceleration and low-speed cruising. On the highway, the Q70 Hybrid uses its aerodynamic design and efficient engine management to maintain strong fuel economy, although the benefits of electric assist are less pronounced at higher, sustained speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Infiniti Q70 Hybrid at $1,750. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. It is a yardstick for comparison, allowing potential buyers to assess the running costs relative to other vehicles in the luxury sedan segment. However, individual fuel costs will vary based on driving habits, local fuel prices, and the proportion of city versus highway driving.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy can differ. Q70 Hybrid drivers have reported experiences that vary based on driving style and conditions. Aggressive acceleration and frequent hard braking will negatively impact fuel economy, while a smoother, more measured approach will yield results closer to the EPA figures. Owners who prioritize maximizing the hybrid system’s benefits in city driving are more likely to meet or exceed the 28 MPG city estimate. The Q70 Hybrid rewards a deliberate driving style that anticipates traffic flow and uses regenerative braking.

How it compares

The 2017 Q70 Hybrid competes in a segment where other hybrid and non-hybrid options exist. The Lexus GS 450h, for example, has a slightly higher combined MPG of 31, with 29 MPG city and 34 MPG highway. While seemingly small, this edge might sway buyers extremely focused on saving fuel. Conversely, the BMW 530e iPerformance, another plug-in hybrid rival from that year, offered a lower combined MPG (27) when running as a standard hybrid (without utilizing its plug-in capability). This shows the Q70 Hybrid’s appeal to those wanting hybrid efficiency without the charging complexities. For those not wholly committed to hybrid technology, the non-hybrid Q70 models with gasoline engines offer more power, but at a cost. The non-hybrid 2017 Infiniti Q70 3.7L V6 achieves a combined MPG of only 21. These factors are important to consider; the Q70 Hybrid positions itself as a balance, offering a refined luxury experience alongside commendable fuel savings.

Tips to maximize efficiency

Use gentle acceleration. The Q70 Hybrid’s electric motor provides instant torque, allowing for effortless acceleration without needing to press the accelerator pedal hard. Gradual acceleration allows the hybrid system to operate more efficiently, reducing the reliance on the gasoline engine and maximizing electric motor usage.

Anticipate traffic and brake smoothly. Look ahead and anticipate traffic flow to minimize the need for hard braking. Smooth, gradual braking allows the regenerative braking system to recapture energy and recharge the battery, improving overall fuel economy. Avoid sudden stops whenever possible.

Use the ECO drive mode. The Q70 Hybrid features an ECO drive mode that optimizes various vehicle settings to enhance fuel efficiency. This mode adjusts throttle response and transmission shift patterns to promote a more economical driving style. While it may slightly reduce performance, the ECO mode can noticeably improve fuel economy, especially on longer drives.

Maintain proper tire inflation. Ensure that your tires are inflated to the recommended pressure, which can be found on the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Regularly checking and maintaining proper tire pressure is a simple yet effective way to optimize efficiency.
