20 MPG combined is the price of entry for driving a modern classic like the 2021 Nissan 370Z. Forget terms like “efficiency” and “economy,” because this car prioritizes the raw, unfiltered driving experience that enthusiasts crave. It’s a rear-wheel-drive, naturally aspirated sports car with a willing V6 and a rewarding manual transmission, appealing to drivers who prioritize engagement over outright thrift. The 370Z buyer knows exactly what they’re getting into, and they accept the fuel consumption as part of the deal.

City and highway performance

The 370Z’s EPA estimates of 17 MPG in the city and 26 MPG on the highway reflect its sporty nature. City driving, with its stop-and-go traffic and frequent bursts of acceleration, is where the Z suffers most. The relatively short gearing and the engine’s eagerness to rev means you’ll be using fuel more often than you might like when navigating urban environments. However, on the open road, the 370Z fares better. At a steady cruise, it achieves a respectable 26 MPG, making it a viable, if not particularly economical, option for weekend getaways and longer road trips. Performance demands fuel, and the 370Z’s V6 is always ready to deliver it.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2021 Nissan 370Z 3.7L 6-cyl is $2,900. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Of course, this is just an estimate. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and fluctuating gas prices. Drivers who primarily use the 370Z for weekend fun runs and track days will likely exceed this figure, while those who use it mainly for highway commuting might see slightly lower costs. However, the EPA figure provides a useful baseline for understanding the car’s overall fuel expenses.

Real-world expectations

While the EPA estimates provide a good starting point, real-world fuel economy can differ significantly. Expect to see numbers closer to 15-16 MPG in the city if you enjoy the engine’s spirited performance, which most 370Z owners do. Highway figures are more likely to align with the EPA’s 26 MPG, but even then, aggressive driving or prolonged high speeds will decrease fuel efficiency. The key takeaway is that the 370Z’s fuel economy is directly tied to how you drive it. Drive it hard, and you’ll pay the price at the pump. Drive it conservatively, and you might get surprisingly close to the official numbers.

How it compares

Compared to other sports cars, the 370Z’s fuel economy sits in a predictable range. A similarly equipped 2021 Ford Mustang EcoBoost, with its 2.3L turbocharged engine, boasts a more frugal 25 MPG combined. However, the Mustang EcoBoost is often cross-shopped by buyers looking for broader appeal, not necessarily the purest driving experience. On the other hand, V8-powered competitors like the Mustang GT are often even less efficient. A 2021 Dodge Challenger R/T, with its 5.7L V8, manages just 19 MPG combined. For drivers prioritizing fuel consumption, it is beneficial to view all Nissan fuel economy data. Those seeking the best possible MPG from a sports car need to evaluate whether they are willing to tradeoff performance and handling.

Tips to maximize efficiency

While the 370Z isn’t known as a fuel sipper, there are a few things you can do to squeeze every last mile out of each gallon. Smooth and predictable driving is important. Avoid aggressive acceleration and hard braking, as these actions significantly increase fuel consumption.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly and inflate them to the recommended levels listed on the door jamb sticker. Doing so will improve fuel efficiency and extend tire life.

Use cruise control on the highway whenever possible. Maintaining a constant speed helps to minimize fuel waste. Cruise control can prevent unintended acceleration and deceleration, further optimizing fuel consumption on long journeys. Understand 370Z MPG across all years to better manage your MPG expectations.

Avoid unnecessary idling. If you’re stopped for more than a minute or two, turn off the engine. Modern cars are designed to restart quickly and efficiently, and idling wastes fuel. This simple habit can make a small but noticeable difference over time.
