21 MPG combined isn’t going to win any hypermiling contests. But the 2020 Acura NSX isn’t about squeezing every last mile from a gallon of premium fuel; it’s about delivering supercar performance with a touch of hybrid efficiency. This isn’t a car purchased for commuting, it’s a statement, an experience, and a technological showcase, where acceptable fuel consumption is merely a side effect.

City and highway performance

The EPA ratings for the 2020 NSX are surprisingly consistent. The City rating mirrors the Combined figure at 21 MPG, while the Highway rating edges slightly higher to 22 MPG. This consistency shows the well-integrated nature of the hybrid powertrain. The electric motors provide a boost off the line and fill in the torque gaps, reducing the need to aggressively use the gas engine in stop-and-go situations. On the highway, the NSX’s aerodynamic design, combined with intelligent powertrain management, maintains respectable efficiency at cruising speeds. While these numbers won’t rival a Prius, Acura’s engineering balances performance and efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Acura NSX at $2,750. This figure is based on driving 15,000 miles per year and using the national average fuel prices for premium gasoline. Remember that this is an estimate. Your actual fuel costs will vary depending on your driving habits, location, and fuel prices in your area. However, it provides a standardized benchmark for comparing fuel costs between different vehicles, but realistically, the NSX buyer isn’t cross-shopping with econoboxes to save on gas. They’re willing to pay for the performance and exclusivity that the NSX offers.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can vary. NSX owners who primarily drive in congested urban environments will likely see figures closer to, or even slightly below, the 21 MPG city rating, especially if they frequently use the instant torque of the electric motors. Conversely, drivers who spend more time on the open highway, using cruise control and avoiding excessive acceleration, might see numbers closer to or slightly above the 22 MPG highway rating. Aggressive driving, track days, and spirited weekend blasts will, of course, significantly reduce fuel economy. Ultimately, the NSX’s fuel economy is heavily dependent on the driver’s style and the driving conditions.

How it compares

Compared to other high-performance machines, the NSX acquits itself reasonably well in the fuel economy stakes. A comparable Porsche 911 Carrera S typically achieves around 20 MPG combined. The Audi R8 V10 fares worse, often struggling to reach 18 MPG in mixed driving. Even the BMW M8 Competition finds it difficult to best 17 MPG. These cars offer similar levels of performance and prestige, but often at the cost of substantially worse fuel efficiency. For buyers considering the NSX, the relatively better mileage is a welcome, if not decisive, factor. For a complete picture, consider all Acura fuel economy data. Also, examine NSX MPG across all years.

Tips to maximize efficiency

Take advantage of the NSX’s electric motor assist during acceleration. Gentle throttle inputs will allow the electric motors to provide a significant boost, reducing the demand on the gasoline engine and improving fuel economy, especially in city driving. Use the “Quiet” drive mode when ultimate performance isn’t required. This mode prioritizes electric operation and reduces throttle response, thereby minimizing fuel consumption during everyday driving.

Maintain consistent highway speeds. The NSX’s aerodynamics are optimized for cruising, but excessive acceleration and deceleration will quickly erode fuel economy. Use cruise control on long stretches of highway to maintain a steady speed and minimize unnecessary fuel burn. Proper tire inflation is also important for maximizing fuel efficiency. Check your tire pressures regularly and maintain them at the recommended levels. Underinflated tires increase rolling resistance, which leads to increased fuel consumption.

Anticipate traffic flow to make the most of regenerative braking. By carefully lifting off the accelerator and allowing the car to coast, the NSX can recover kinetic energy and recharge the battery, further improving fuel economy. Avoid abrupt braking, as this wastes energy and doesn’t allow the regenerative braking system to function optimally.
