21 MPG combined might raise eyebrows for a modern hybrid, but for the 2019 Acura NSX, it shows the vehicle’s main focus: performance. It’s not a Prius; it’s a mid-engine, all-wheel-drive supercar with a complex hybrid system designed to improve acceleration and handling, not maximize efficiency. The NSX buyer isn’t primarily concerned with fuel costs. They’re buying a statement, advanced technology, and a driving experience that few cars can match. Fuel economy is a secondary consideration for an enthusiast vehicle like this.

City and highway performance

The EPA estimates that the 2019 NSX gets 21 MPG in both city and highway driving. This consistency shows how the NSX’s hybrid system supplements the powerful 3.5L twin-turbocharged V6 engine. The electric motors provide instant torque, improving acceleration in urban environments and helping the gasoline engine during highway cruising. Some hybrids become less efficient at higher speeds, but the NSX’s strong powertrain maintains consistent fuel consumption. The 9-speed dual-clutch automatic transmission (AM-S9) helps provide stable fuel economy, choosing gears for performance and efficiency. This makes the NSX fuel consumption predictable, even if it isn’t class-leading.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Acura NSX is $2,750. This is based on 15,000 miles per year and the national average fuel price when calculated. It’s a good way to compare running costs with other vehicles. Fuel prices change, and driving habits affect your actual cost. The EPA’s $2,750 is a standard for assessing the NSX’s fuel expenses but likely isn’t the primary factor when deciding to buy.

Real-world expectations

EPA estimates are a guide, but real-world fuel economy varies. Aggressive driving, using the car’s acceleration, and outside temperature can all affect MPG. NSX owners who track their cars or enjoy weekend drives will likely see lower numbers than the EPA estimates. Alternatively, those who cruise may get better mileage. The NSX’s hybrid system complements performance, which results in driving that doesn’t achieve the highest possible fuel economy.

How it compares

The Acura NSX is unique in the supercar market. It’s a hybrid, but not one focused on efficiency. A Porsche 911 Carrera S, which isn’t a hybrid, gets around 20 MPG combined, like the NSX, but offers a different driving experience. The Audi R8, a V10-powered competitor, typically gets around 16 MPG combined, highlighting the NSX’s fuel efficiency in this performance class. The BMW i8, a hybrid sports car with a focus on efficiency, achieved 28 MPG combined, but its performance is different from the NSX. Considering all Acura fuel economy data reveals the NSX’s place within the brand’s lineup, and checking NSX MPG across all years emphasizes its position relative to past versions. This comparison shows that the NSX buyer is prioritizing a blend of performance and technology over fuel savings.

Tips to maximize efficiency

The NSX is a performance car, but you can still improve fuel economy slightly.

Avoid accelerating quickly and braking hard. The hybrid system is most efficient when operating smoothly. Sudden bursts of speed drain the battery and force the gasoline engine to work harder.

Use the NSX’s driving modes. The “Quiet” mode drives on electric power at lower speeds, reducing fuel consumption in stop-and-go traffic. It won’t make the NSX an efficient commuter, but it can make a difference in city driving.

Keep your NSX maintained. Checking tire pressure and following the service schedule will improve performance and fuel efficiency. Underinflated tires increase rolling resistance, requiring more energy to move the car, and a well-maintained engine runs more efficiently.

Consider driving without using the automatic paddle shifters unless you need to. Allow the 9-speed’s computer to keep the engine within its best range of power and fuel consumption. When you use the paddles, remember to take the car out of manual mode to allow the computer to achieve optimal MPG.
