21 MPG combined isn’t going to win any hypermiling competitions, but for the 2017 Acura NSX Hybrid, it’s a figure born of compromise, a balance between supercar velocity and some responsibility. This isn’t a car purchased by those prioritizing fuel efficiency above all else. It’s chosen by individuals seeking cutting-edge technology, breathtaking performance, and a distinctive presence, accepting the fuel economy as a necessary consequence.

City and highway performance

The EPA estimates a city MPG of 21 and a highway MPG of 22 for the 2017 NSX. The relatively consistent figures highlight the efficiency of the hybrid system working with the 3.5L twin-turbocharged V6. While some cars see a significant drop in city MPG due to stop-and-go traffic, the NSX’s electric motors assist during acceleration, reducing the reliance on the gasoline engine. On the highway, the NSX excels as a grand tourer with passing power. That power comes at a price, though; push the car hard, and those MPG numbers quickly diminish. The nine-speed dual-clutch transmission (AM-S9) is programmed for rapid shifts during spirited driving, and optimized gear selection for relaxed cruising.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Acura NSX to be exactly $2,750. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, using the EPA’s fuel consumption estimates and national average fuel prices. It provides a standardized benchmark allowing consumers to compare the cost of fueling different vehicles. Remember that individual driving habits, fuel prices in your location, and the grade of fuel used can all impact your actual fuel expenditure.

Real-world expectations

Drivers who frequently exploit the NSX’s immense performance capabilities will likely see fuel economy figures below the EPA estimates. On the other hand, conscientious drivers who prioritize smooth acceleration and anticipate traffic flow can potentially achieve MPG closer to, or even slightly above, the EPA numbers. This car rewards a smooth driving style. The instant torque provided by the electric motors allows you to accelerate and merge into traffic with ease, without needing to push hard on the gas pedal.

The temptation to experience the full force of the twin-turbo V6 is always there, and repeated indulgence will negatively impact fuel economy. For a broader perspective, review NSX MPG across all years.

How it compares

Compared to other high-performance coupes and supercars, the NSX’s fuel economy is a mixed bag. The Porsche 911 Carrera S, while not a hybrid, can achieve around 21 MPG combined in real-world driving, similar to the NSX. However, more powerful versions of the 911, like the Turbo S, see considerably lower fuel economy figures. The Audi R8, with its naturally aspirated V10, typically achieves around 16 MPG combined. When considering other hybrid performance coupes, options are limited. The BMW i8, though stylistically similar, prioritizes efficiency over raw power and delivers significantly higher MPG, hovering around 28 MPG combined.

Tips to maximize efficiency

Use the NSX’s regenerative braking system to recapture energy and minimize reliance on the friction brakes. Anticipate traffic conditions and coast whenever possible, allowing the electric motors to slow the car down and recharge the battery.

Select the “Quiet” or “Sport” driving modes for everyday commuting. These modes prioritize electric power and fuel efficiency, while still providing adequate performance for most driving situations. Avoid “Track” mode unless you’re actually on a track; it prioritizes performance above all else.

Ensure that your tires are properly inflated and well-maintained. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Regularly check your tire pressure and ensure that it meets the manufacturer’s specifications.

Keep the vehicle weight down. Unnecessary cargo increases the energy required to accelerate and maintain speed. Remove any items from the trunk or passenger compartment that are not essential.

Avoid aggressive driving habits, such as rapid acceleration, hard braking, and excessive speeding. Smooth and consistent driving minimizes fuel consumption and maximizes the efficiency of the hybrid system.
