30 MPG combined is a respectable figure for the 2015 Infiniti Q50 Hybrid AWD. This Q50 variant is an interesting choice for buyers who want both luxury and efficiency, especially those who don’t want to give up the security of all-wheel drive or the satisfying power of a V6 engine.

City and highway performance

The EPA estimates the 2015 Q50 Hybrid AWD at 28 MPG in the city and 34 MPG on the highway. These numbers show what the hybrid powertrain can do: the electric motor helps the gasoline engine when you’re stopping and starting, improving efficiency in cities. The highway figure shows that the Q50 Hybrid can drive quietly and economically at higher speeds, making it a good choice for longer commutes or road trips. The automatic transmission (S7) makes for smooth transitions for efficiency. Keep in mind that these figures are benchmarks, your driving style and the conditions will change your real-world results.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Infiniti Q50 Hybrid AWD at $1,950. This is based on driving 15,000 miles per year and using the national average price of gasoline when the EPA tested the car. Fuel prices change, but this figure gives you a standard to compare the Q50 Hybrid’s running costs to other vehicles. It’s a useful figure for those thinking about the upfront cost of a luxury car and how affordable it will be over time.

Real-world expectations

The EPA estimates give you a good starting point, but your fuel economy may be different. If you accelerate hard, brake often, and speed, your MPG will go down. But if you drive more smoothly, you may get closer to the EPA’s numbers, or even better. How warm it is, your tire pressure, and if you use accessories like air conditioning will also affect your fuel use. The Q50 Hybrid rewards careful drivers, but it’s also a car that invites spirited driving, so be mindful of your right foot.

How it compares

The 2015 Q50 Hybrid is competitive among luxury hybrid sedans with all-wheel drive. A similar 2015 Lexus ES 300h (front-wheel drive only) gets an EPA-estimated 40 MPG combined, showing its great efficiency, but it doesn’t have the Q50’s sporty driving. The Acura RLX Sport Hybrid SH-AWD, from the same time, offers a similar performance-focused hybrid, but its fuel economy (29 MPG combined) is a little lower than the Q50 Hybrid. If prestige matters, some BMW models have hybrid options, but they often need premium fuel and cost more. For a look at all Infiniti fuel economy data, resources like FuelEconomyHub can provide useful comparisons. Buyers who want to know about Q50 MPG across all years can do more research.

Tips to maximize efficiency

Use the Q50 Hybrid’s regenerative braking system. Plan your stops and slow down slowly, which lets the system get energy back and recharge the battery. This works especially well when you’re driving in the city and stopping often.

Watch how you drive and try not to accelerate hard or brake hard. The Q50 Hybrid has displays that show you your fuel economy in real-time, which helps you see and change what you do that hurts efficiency. Drive smoothly and consistently to get the best MPG.

Make sure your tires have the right amount of air. If your tires don’t have enough air, they create more rolling resistance, which makes the engine work harder and use more fuel. Check your tire pressure regularly and keep it at the levels in your owner’s manual.

Don’t use accessories as much, especially air conditioning, since they put a lot of strain on the engine and reduce fuel economy. When you can, use the Q50 Hybrid’s ventilation system or open the windows instead. But on the highway, air conditioning can be more efficient than opening windows because of aerodynamic drag.
