22 MPG combined. No one buys a 2018 Nissan 370Z expecting Prius-level fuel efficiency. This is a two-seat sports car with a V6 engine designed for spirited driving. The 370Z buyer prioritizes performance and driving experience over saving a few dollars at the pump, and they accept the fuel economy tradeoff as part of the overall package.

City and highway performance

The 2018 Nissan 370Z, equipped with its 3.7-liter V6 and the automatic (S7) transmission, achieves 19 MPG in the city and 26 MPG on the highway. These numbers reflect the engine’s responsiveness and the transmission’s tuning. The city MPG figure is largely affected by stop-and-go traffic where the engine is working harder to accelerate the Z’s weight from a standstill.

Highway MPG is more palatable because at cruising speed, the engine isn’t working as hard, allowing it to achieve its best possible fuel economy. The difference between city and highway numbers also shows the car’s design: backroad blasts and weekend jaunts are preferable to bumper-to-bumper commuting, and the car’s fuel economy reflects that.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Nissan 370Z at $2,650. This is based on driving 15,000 miles per year and using national average fuel prices. Fuel prices can fluctuate significantly depending on location and time of year, so your actual fuel costs may vary. The EPA’s number provides a baseline for comparison against other vehicles, but individual driving habits will play a big role in determining your real-world expenses. Buyers can find all Nissan fuel economy data to determine whether another model would be a better fit for their driving habits.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can differ. Aggressive driving and frequent short trips where the engine doesn’t reach optimal operating temperature impact fuel efficiency, and even tire pressure affects it too.

Owners who prioritize smooth acceleration, maintain proper tire inflation, and minimize idling are more likely to approach the EPA estimates. Those who frequently exploit the engine’s power and enjoy spirited driving should expect slightly lower numbers. Given the 370Z’s performance-oriented mission, most drivers will enjoy the car, resulting in fuel economy on the lower end of the EPA range.

How it compares

Compared to its rivals, the 2018 Nissan 370Z’s fuel economy is typical of sports cars in its class. The BMW M2, while offering superior performance, gets around 20 MPG combined. A Ford Mustang GT, depending on the engine and transmission configuration, lands around 19 MPG combined. Even the four-cylinder Chevrolet Camaro manages only around 25 MPG combined in its most efficient configuration.

The 370Z isn’t trying to be an economy car, it’s a focused sports car. Potential buyers should review the 370Z MPG across all years to see if other model years could offer a better balance. This comparison matters because the 370Z isn’t intended to be the most fuel-efficient option, but understanding its place within the sports car landscape helps buyers align their expectations and priorities.

Tips to maximize efficiency

The 3.7-liter V6 responds well to smooth, deliberate inputs. Avoid aggressive acceleration and abrupt braking, as these actions force the engine to work harder and burn more fuel. Gentle acceleration and anticipating traffic flow will help you optimize fuel consumption without sacrificing too much enjoyment of the car’s performance.

Proper tire inflation is important for maximizing fuel economy. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure and check your tire pressure regularly, especially during temperature changes. Underinflated tires increase rolling resistance, which negatively impacts fuel efficiency. A small investment in a tire pressure gauge can save you money at the pump.

Minimize idling whenever possible. Modern engines are designed to be efficient at operating temperature, and unnecessary idling wastes fuel without contributing to meaningful engine warm-up. If you anticipate being stationary for more than a minute or two, turn off the engine. Every little bit helps.

Use the highest gear possible without lugging the engine. The automatic transmission is designed to shift efficiently, but you can further optimize fuel consumption by avoiding aggressive downshifts and choosing a gear that allows the engine to operate in its optimal range. Listen to the engine and avoid pushing it harder than necessary to maintain your desired speed.
