The 2021 Acura NSX gets 21 MPG combined, and that figure won’t deter its core customer. The NSX isn’t about maximizing miles per gallon; it’s about maximizing driving thrills with hybrid efficiency. Owners prioritize the cutting-edge technology, supercar design, and exhilarating performance that the hybrid powertrain delivers. They accept the fuel economy as a tradeoff for a unique driving experience.

City and highway performance

The NSX’s EPA ratings show a surprising consistency between city and highway driving: 21 MPG in the city and 22 MPG on the highway. This suggests the hybrid system is effectively used in both environments, providing electric assistance and regenerative braking benefits whether navigating urban streets or cruising on the open road. The driver’s acceleration habits will have a greater impact on fuel economy than the environment. A gentle right foot will be rewarded; aggressive launches will drain the tank faster.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2021 Acura NSX is $2,750. This is based on estimates of 15,000 miles per year and using national average fuel prices. Fluctuations in fuel prices will impact this cost, offering a baseline for budgeting. The $2,750 figure represents the monetary aspect of owning a performance car with a hybrid powertrain, a price some drivers happily pay for the NSX experience.

Real-world expectations

While EPA estimates offer a benchmark, real-world fuel economy in the NSX will vary significantly based on driving style and conditions. Drivers who frequently engage the Sport or Track modes and exploit the car’s performance should expect figures below the EPA estimates. Drivers who prioritize smooth acceleration and use the electric motor when possible may see slightly improved results, though matching the theoretical maximum is rarely achievable in a performance vehicle.

How it compares

The NSX is unique when considering fuel economy because its main competitors are not often hybrids. The Porsche 911 Carrera S, for example, achieves around 20 MPG combined, and its Targa version gets 19 MPG. These figures are close to the NSX’s, but without the hybrid system. The Audi R8 V10 performance offers around 16 MPG combined, highlighting the NSX’s relative efficiency in the supercar segment. The NSX can offer similar performance to these traditional gasoline-powered competitors with a modest improvement in fuel economy.

Tips to maximize efficiency

Take advantage of the NSX’s hybrid system in everyday driving. Gentle acceleration allows the electric motors to provide primary propulsion, reducing reliance on the gasoline engine and saving fuel. Resist the urge to show off the car’s acceleration, especially in city driving.

Use regenerative braking effectively. Anticipate traffic stops and coast when possible, allowing the electric motors to recapture energy and recharge the battery. This improves efficiency and reduces wear on the conventional brake pads. Avoid heavy braking unless necessary.

Monitor the energy flow display. The NSX’s infotainment system provides a visual representation of the hybrid system’s operation. Pay attention to when the electric motors are engaged, and adjust your driving style to maximize their presence. This visual feedback allows drivers to understand how their driving habits affect fuel consumption.

Consider tire pressure and alignment. Properly inflated tires reduce rolling resistance, improving fuel economy. A misaligned suspension can increase drag and negatively impact efficiency. Regularly check tire pressure and ensure the alignment is within factory specifications.
