Best INFINITI SUVs for Gas Mileage

November 4th, 2022 by

SUVs are popular among single-car families, so automakers are working hard to make them more fuel-efficient, reducing the cost of driving them to everyone’s weekly destinations. The INFINITI SUV lineup offers high-value, luxurious vehicles with various powertrains and exceptional fuel economy. These vehicles range from the midsized QX50 and QX55 to the family-friendly QX60 and commanding QX80. To find out which is efficient enough to meet your needs, check out some of the best INFINITI SUVs for gas mileage.


Combining luxury, technology, and a roomy interior, the new INFINITI QX50 also benefits from being the best INFINITI SUV for fuel economy. The QX50’s gas mileage is estimated at 23 mpg in the city and 29 mpg on the highway with the standard front-wheel drive, or 22 city mpg and up to 28 highway mpg with the all-wheel drive. These fuel economy ratings lead to a combined 26 mpg, quite respectable for a high-end compact SUV.

The 2022 QX50 is offered in five trim levels: Pure, Luxe, Essential, Sensory, and Autograph. Each trim level is powered by a 2.0-liter turbocharged four-cylinder engine, generating 268 horsepower and 280 lb-ft of torque on top of the competitive fuel ratings.


The 2022 INFINITI QX55 is an affordable and practical luxury compact SUV. All 2022 QX55 models have an all-wheel-drive system, a continuously variable automatic transmission, and a 268-horsepower turbocharged four-cylinder engine. The QX55 is confidently propelled off the line by this engine, which also offers enough thrust for commuting. The estimated city and highway mpg for the INFINITI QX55 are 22 and 28, respectively. This model is tied for second place with the Q60 for the most efficient INFINITI SUV.


The 2022 INFINITI QX60 offers much of the same value as the QX50, only in a larger body and with a more robust engine. It has a solid but comfortable ride, a respectable V-6 engine, and good handling, all to be expected from this top-level manufacturer. All trim levels use a 295-horsepower V-6 engine mated to a nine-speed automatic transmission.

The QX60 can reach fuel efficiency ratings of 21 mpg in the city and 26 mpg on the highway with front-wheel drive. And the powertrain provides brisk acceleration in town and lots of power for passing on the highway. The transmission generally responds quickly and smoothly, a side benefit of the efficiency-minded powertrain setup.


The 5.6-liter V-8 in the full-size QX80 generates 400 horsepower and 413 lb-ft of torque, and it can be equipped with rear- or four-wheel drive. Despite being the largest and heaviest vehicle produced by the company, the QX80 is easily propelled off the line by this powerful engine. The 2022 edition earned EPA ratings of 14 mpg in the city and 20 mpg on the highway. The engine has strong passing power on the highway and ample pulling power at low speeds, and the transmission shifts smoothly and quickly through the gears.

It’s worth noting that the future INFINITI SUVs bring new levels of efficiency, such as the upcoming QX Inspiration and Inspiration Sport, two full-electric concept SUVs. In the future, we’re sure to see even better fuel and travel economy for the INFINITI lineup.

Other Efficient INFINITI Models

INFINITI is well-known for efficient SUVs and cars, so you’ll find good fuel economy from either vehicle type. For instance, the four-seat 2022 INFINITI Q60 sedan is available in three trim levels, including the high-demand Luxe with its unique 3.0-liter V-6 twin-turbo engine. The standard Q60’s 295 lb-ft of torque and 300 horsepower provide the ideal balance of speed and pull, and being able to travel up to 19 mpg in the city and 28 mpg on the highway is even better. The lightweight aluminum V-6 engine also benefits from advanced cooling and variable valve timing technology.

The last INFINITI vehicle in the current lineup is the Q50 sedan, which has more substantial fuel ratings, a ton of standard features, and a cozy interior. The Q50 goes one point higher than the Q60, earning 20 mpg in the city and 29 mpg on the highway on the right models. A twin-turbo 3.0-liter V-6, a seven-speed automatic transmission, and rear-wheel drive are standard, but all-wheel drive is also available. The Red Sport 400 is tuned to produce 400 horsepower, while all other car versions have a respectable 300 horsepower.

No matter the drivetrain setup or engine output, a new or certified pre-owned INFINITI vehicle will have competitive fuel economy ratings. That applies to both the SUVs and sedans for sale.
