18 MPG combined is simply a cost of doing business when you’re piloting a Nissan GT-R. Nobody buys Godzilla thinking it will sip fuel like a Prius. This is a car built for performance, and the thirsty 3.8-liter twin-turbo V6 under the hood confirms that mission with every glorious, guttural growl.

City and highway performance

The EPA estimates the 2021 Nissan GT-R at 16 MPG in the city and 22 MPG on the highway. These figures reflect the immense power being managed by the advanced all-wheel-drive system and the six-speed dual-clutch transmission. Stop-and-go traffic will punish the GT-R’s fuel economy, as the turbos spool and the engine delivers instant torque. However, on the open road, the highway figure offers a slightly more palatable glimpse into what’s possible when the car is allowed to stretch its legs, though few GT-R owners will be resisting the urge to dip into the immense performance on tap.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2021 Nissan GT-R is $3,200. This calculation is based on driving 15,000 miles per year and using national average fuel prices for premium gasoline. Be aware that if you drive more aggressively, live in an area with higher fuel costs, or exceed the 15,000-mile benchmark, your expenses will likely be substantially higher.

Real-world expectations

While the EPA provides a useful baseline, real-world MPG for the GT-R can vary considerably. Drivers who frequently engage in spirited acceleration or track days will see significantly lower numbers. Conversely, those who primarily use the GT-R for longer highway journeys and adopt a gentler driving style might achieve figures closer to, or even slightly above, the EPA estimates. Consider the GT-R’s performance capabilities and imagine your driving habits; plan accordingly. You can also see GT R MPG across all years.

How it compares

Competitors offer a range of fuel economy figures that are important for potential buyers to consider. The Porsche 911 Carrera S, while similarly focused on performance, achieves a slightly better 21 MPG combined. The Chevrolet Corvette C8, with its mid-engine layout and potent V8, manages a respectable 19 MPG combined. The Audi R8, equipped with a naturally aspirated V10, lands around 16 MPG combined. The GT-R’s specific target audience values raw performance and engineering prowess above all else, but this comparison highlights the trade-offs that buyers are willing to make.

Tips to maximize efficiency

While the GT-R isn’t fundamentally designed for fuel efficiency, there are still some techniques to minimize consumption. Avoid unnecessary hard acceleration, which forces the turbos to spool up, dramatically increasing fuel usage. Instead, adopt a smoother, more progressive throttle input, especially in city driving. Use the car’s customizable drive modes to select settings that prioritize fuel efficiency when track-day performance is not a priority.

Regular maintenance is critical for optimal fuel economy. Ensure the tires are properly inflated. Underinflated tires increase rolling resistance, which decreases MPG. and schedule routine engine check-ups to maintain optimal operation. Clean or replace the air filter regularly to ensure the engine is breathing efficiently.

Minimize idling. The GT-R’s engine consumes a noticeable amount of fuel while idling. Turn off the engine if you anticipate a prolonged stop, such as waiting in a parking lot or at a train crossing. This simple habit can make a small but meaningful difference over time. Also, keep cargo weight down. Excess weight reduces fuel efficiency in almost all vehicles.

Consider limiting track days. While tempting, repeated hard driving on track will decimate your fuel economy and increase wear and tear. If you must drive aggressively, consider joining an autocross event. The speeds are slower, but you can still practice your skills while conserving your fuel.
