21 MPG combined won’t win any awards for lower fuel costs, but it’s what you get with a specific brand of driving thrills delivered by the 2015 Nissan 370Z. This isn’t a car bought for saving money on gas; it’s purchased by enthusiasts who prioritize engaging handling, a strong V6 engine, and classic sports car styling. They understand the tradeoff. For them, the smile it puts on their face more than makes up for the fuel stops.

City and highway performance

The EPA estimates for the 2015 370Z with the automatic transmission are 19 MPG in the city and 26 MPG on the highway. These figures accurately reflect how the car behaves. While the 3.7-liter V6 is easy to manage around town, its true nature comes out when you rev the engine high, where the fuel consumption takes a hit. On the open road, cruising at a steady speed, the 370Z is surprisingly efficient, especially when equipped with the seven-speed automatic transmission. That transmission helps keep the engine in its sweet spot without burning excessive fuel.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2015 Nissan 370Z is $2,750. This calculation is based on driving 15,000 miles per year and using the national average fuel price at the time of assessment. Individual fuel costs will vary depending on driving habits and fluctuations in fuel prices. This figure is a benchmark for potential owners to consider when budgeting for their vehicle.

Real-world expectations

Official EPA numbers offer a way to compare vehicles, but real-world fuel economy depends on driving style, traffic, and even tire pressure. Expect to achieve figures close to the EPA estimates if you drive conservatively, but frequent bursts of acceleration and spirited driving will reduce your MPG. Owners reporting their own figures on fuel economy websites suggest a range of 17-24 MPG in mixed driving is common, with 28-30 MPG achievable on longer highway journeys at moderate speeds. To see 370Z MPG across all years, reviewing owner-submitted data gives a clearer picture of typical performance in varied conditions.

How it compares

Compared to its rivals, the 2015 Nissan 370Z is in the middle of the pack. Consider the Subaru BRZ/Scion FR-S twins (RIP Scion). Although they have less power, their lighter weight and focus on handling purity lead to considerably better fuel economy, around 25 MPG combined. A Ford Mustang GT has significantly more power but sacrifices some economy at roughly 19 MPG combined. However, it is more practical and larger. The now-discontinued Hyundai Genesis Coupe, with its available V6 engine, offered similar performance and fuel economy to the 370Z. This context matters because the Z buyer is often cross-shopping these types of vehicles. They are trying to weigh performance and style versus fuel economy. For these buyers, checking all Nissan fuel economy data is another good resource.

Tips to maximize efficiency

Use premium fuel as recommended. While the 370Z can technically run on regular unleaded gasoline, using premium fuel will ensure optimal performance and efficiency. The engine’s high compression ratio benefits from the higher octane, maximizing power output and reducing the risk of knocking, which helps maintain fuel economy.

Maintain optimal tire pressure. Underinflated tires increase rolling resistance. This forces the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels found on the driver’s side door jamb. This improves fuel efficiency and extends tire life and enhances handling.

Anticipate traffic flow and avoid aggressive acceleration. The 370Z’s powerful engine is tempting to unleash, but frequent hard acceleration and braking significantly reduce fuel economy. Drive smoothly, anticipate traffic patterns, and maintain a steady speed whenever possible. Using the cruise control on the highway can help maintain efficiency on longer drives.

Reduce unnecessary weight. Carrying extra weight in your vehicle reduces fuel economy. Remove any unnecessary items from the trunk and interior to lighten the load. This small change can make a noticeable difference over time, especially during city driving.

Keep your vehicle properly maintained. Regular maintenance, including oil changes, air filter replacements, and spark plug inspections, ensures that the engine is running efficiently. A poorly maintained engine consumes more fuel and produces higher emissions. Following the manufacturer’s recommended maintenance schedule will help keep your 370Z running at its best.
