The Most Fuel-Efficient 2027 INFINITI Vehicles for Ontario Drivers
The Most Fuel-Efficient 2027 INFINITI Vehicles for Ontario Drivers
Posted on August 16, 2026
Fuel costs add up over a year of commutes, school runs and weekend trips. That is why fuel consumption is one of the first numbers many shoppers check when they compare luxury SUVs. The 2027 INFINITI lineup gives you three clear choices, and each one carries official Natural Resources Canada (NRCan) ratings you can use to compare them side by side.
This guide ranks the 2027 INFINITI QX60, QX65 and QX80 by fuel use, explains what powers each one, and helps you match the right model to the way you drive. All figures are NRCan estimates in litres per 100 kilometres (L/100 km). A lower number means the vehicle uses less fuel to cover the same distance.
At a Glance: 2027 INFINITI Fuel Consumption Ranked
| Rank | Model | Engine | City (L/100 km) | Highway (L/100 km) | Combined (L/100 km) | CO2 (g/km) |
| 1 | 2027 INFINITI QX60 AWD | 2.0 L 4-cylinder VC-Turbo | 10.9 | 8.8 | 10.0 | 235 |
| 2 | 2027 INFINITI QX65 AWD | 2.0 L 4-cylinder VC-Turbo | 11.2 | 8.7 | 10.1 | 237 |
| 3 | 2027 INFINITI QX80 4WD | 3.5 L twin-turbo V6 | 15.1 | 12.3 | 13.8 | 325 |
2027 INFINITI QX60: The Lineup’s Most Fuel-Efficient Pick
The 2027 INFINITI QX60 AWD earns the top spot with a combined rating of 10.0 L/100 km. It also posts the lowest city figure in the lineup at 10.9 L/100 km, along with 8.8 L/100 km on the highway and the lowest CO2 rating of the three at 235 g/km.
Power comes from a 2.0 L 4-cylinder Variable Compression Turbo (VC-Turbo) engine rated at 268 hp and 286 lb-ft of torque. This engine changes its compression ratio based on how hard you press the accelerator. It gives you strong response for passing and keeps fuel use in check during relaxed driving. A 9-speed automatic transmission with paddle shifters sends power to all four wheels.
The QX60 also stands out beyond the INFINITI showroom. Among 11 gasoline-only large luxury SUVs in a manufacturer-defined segment, the QX60 AWD has the lowest estimated city, highway and combined fuel consumption, based on Government of Canada-approved test methods.
The QX60 also gives the whole family room to spread out, with three rows of seats, 411 L of cargo space behind the third row, growing to 2,135 L with the second and third rows folded. It is offered in LUXE, SPORT and AUTOGRAPH grades.
- 10.0 L/100 km combined, the lowest in the 2027 INFINITI lineup
- 10.9 L/100 km city and 8.8 L/100 km highway
- Three rows with up to 2,135 L of cargo space
- Towing capacity of up to 6,000 lbs (2,722 kg) when properly equipped
2027 INFINITI QX65: The Lowest Highway Rating in the Lineup
The all-new 2027 INFINITI QX65 AWD owns one clear fuel win: its 8.7 L/100 km highway rating is the lowest of any 2027 INFINITI. Its combined figure of 10.1 L/100 km sits just 0.1 L/100 km behind the QX60, and it uses 11.2 L/100 km in the city.
The QX65 uses the same 2.0 L 4-cylinder VC-Turbo engine with 268 hp and 286 lb-ft of torque. INFINITI tuned its 9-speed automatic transmission with a sportier shift schedule, so the QX65 feels eager off the line and confident when merging. Intelligent All-Wheel Drive is standard.
The fastback shape still leaves room for real life. You get 1,014 L of cargo space behind the second row and 1,917 L with the second row folded. Towing capacity reaches 6,000 lbs (2,722 kg) when properly equipped. The QX65 comes in LUXE, SPORT and AUTOGRAPH grades.
For drivers who spend most of their time at steady highway speeds, the QX65 gives you the lowest highway fuel rating INFINITI offers, wrapped in its sportiest design.
2027 INFINITI QX80: Full-Size Capability With 450 hp
The 2027 INFINITI QX80 4WD is the flagship of the lineup. It is rated at 15.1 L/100 km city, 12.3 L/100 km highway and 13.8 L/100 km combined.
Under the hood sits a 3.5 L twin-turbo V6 with 450 hp and 516 lb-ft of torque. The 9-speed automatic transmission uses a wide range of gear ratios, which helps with quick acceleration and efficient highway cruising. That explains the gap between its city and highway figures. All-Mode 4-Wheel Drive comes on every QX80.
The QX80 is built for the biggest jobs. The LUXE grade seats eight, while SPORT and AUTOGRAPH seat seven. Cargo space measures 622.9 L behind the third row and 2,860 L with the second and third rows folded. Towing capacity reaches 8,500 lbs (3,856 kg) when properly equipped, and the 89.3 L fuel tank supports long trips between stops.
How to Read NRCan Fuel Ratings
NRCan publishes three numbers for each vehicle. The city rating reflects stop-and-go driving, the highway rating reflects steady cruising, and the combined rating uses both results to give you one figure for everyday comparison.
Look at the number that matches most of your driving. City-heavy drivers should focus on the city rating, while long-distance commuters get more value from the highway figure. Your actual fuel use will vary with driving conditions, weather and how you use the vehicle.
Which Fuel-Efficient INFINITI Fits Your Driving?
All three 2027 INFINITI models use a 9-speed automatic transmission and full-time traction, so the right choice comes down to seating, style and where you drive most.
- Choose the 2027 QX60 if you want the lowest combined and city fuel use in the lineup, plus three rows of seating for a growing family.
- Choose the 2027 QX65 if most of your kilometres are on the highway and you want the lowest highway rating with a sporty fastback design.
- Choose the 2027 QX80 if you need seating for up to eight, 450 hp and towing capacity of up to 8,500 lbs (3,856 kg).
