Jeep Grand Cherokee fuel economy for 2026 runs from 10.4 L/100 km combined, with the 2.0 litre Hurricane 4 Turbo in the two row Grand Cherokee, to 11.3 L/100 km combined, with the 3.6 litre Pentastar V6 in the three row Grand Cherokee L. Those are Natural Resources Canada's ratings. On the highway the two engines are rated the same, 9.2 L/100 km in the two row, so the engine you pick matters most in town. When you know which number fits your driving, you can browse new Jeep Grand Cherokee inventory by engine and trim.
The engine follows the trim, and our Laredo versus Altitude versus Limited comparison shows where it changes, at the Altitude. Below the ratings: what minus 25, remote start, winter tires and a roof box do to the number.
Key Takeaways
- The 2.0 litre Hurricane 4 Turbo is the efficiency pick. Natural Resources Canada rates it at 10.4 L/100 km combined in the two row Grand Cherokee and 10.7 in the Grand Cherokee L, on regular gasoline.
- The 3.6 litre Pentastar V6 is rated 0.5 to 0.6 L/100 km higher combined. 10.9 in the two row and 11.3 in the L. The gap is in the city; on the highway the two engines tie.
- The three row L costs a little. 0.3 L/100 km more combined with the Hurricane 4 Turbo and 0.4 more with the Pentastar V6.
- Cold weather can raise the number on any Grand Cherokee. To size it on yours, note the litres and kilometres over two fill ups in January and two in July.
- There is no 2026 Grand Cherokee 4xe. Jeep Canada's current pages list gas engines only; the 4xe is a used vehicle question.
Jeep Grand Cherokee Fuel Economy in L/100 km
These are the Natural Resources Canada fuel consumption ratings for the 2026 model year. Every 2026 Grand Cherokee in the file is a 4X4 with an eight speed automatic, rated on regular gasoline. The km per litre column is our conversion of the official combined figure (100 divided by the L/100 km rating), rounded to one decimal.
| 2026 Grand Cherokee version | Combined L/100 km | About km per litre |
|---|---|---|
| 2.0 Hurricane 4 Turbo, two row | 10.4 | 9.6 |
| 2.0 Hurricane 4 Turbo, Grand Cherokee L | 10.7 | 9.3 |
| 3.6 Pentastar V6, two row | 10.9 | 9.2 |
| 3.6 Pentastar V6, Grand Cherokee L | 11.3 | 8.8 |
City and highway as Natural Resources Canada prints them, with its own combined figure in miles per imperial gallon.
2.0 litre Hurricane 4 Turbo, two row Grand Cherokee. 11.5 city, 9.2 highway, 10.4 combined (27 mpg). Jeep Canada lists up to 324 horsepower.
2.0 litre Hurricane 4 Turbo, Grand Cherokee L. 11.7 city, 9.4 highway, 10.7 combined (26 mpg).
3.6 litre Pentastar V6, two row Grand Cherokee. 12.3 city, 9.2 highway, 10.9 combined (26 mpg). Jeep Canada lists up to 293 horsepower.
3.6 litre Pentastar V6, Grand Cherokee L. 13.0 city, 9.4 highway, 11.3 combined (25 mpg).
Natural Resources Canada files both Pentastar V6 rows under the name Classic.
Which Engine Comes on Which Trim
Jeep Canada's 2026 capability page says the 2.0 litre Hurricane 4 Turbo is "Not available on Laredo and Laredo X". Its 2026 models page lists the 3.6 litre Pentastar V6 on the Laredo and Laredo X, and the Hurricane 4 Turbo on the Altitude, the Limited and the 85th Anniversary Edition. Choosing a trim chooses your fuel rating, so check the engine line on the window sticker.
Reading the Numbers
The 2.0 litre Hurricane 4 Turbo wins in the city by 0.8 L/100 km in the two row, 11.5 against 12.3, and by 1.3 in the L, 11.7 against 13.0. On the highway it is a tie: 9.2 for both engines in the two row and 9.4 for both in the L. If your kilometres are mostly on the Trans-Canada Highway between Portage la Prairie and Winnipeg, the engine barely moves your highway number. If your week is school runs and town errands, the Hurricane 4 Turbo saves fuel.
For a 2025 or earlier Grand Cherokee, or for a 2027, look up that model year in Natural Resources Canada's fuel consumption ratings search tool. Jeep Canada's 2027 Grand Cherokee capability page lists the same two engines and prints the same combined figures, 10.4 for the Hurricane 4 Turbo and 10.9 for the Pentastar V6.
Two Row or Grand Cherokee L
The longer three row body costs 0.3 L/100 km combined with the Hurricane 4 Turbo and 0.4 with the Pentastar V6. That is small next to the question that really decides it: whether you need the third row. Our Grand Cherokee versus Grand Cherokee L comparison walks through seating and cargo, and you can see new Grand Cherokee L inventory if the third row is the answer.
What a Manitoba Winter Does to the Number
Natural Resources Canada is plain that "Your vehicle's fuel consumption will vary from its published fuel consumption ratings, depending on how, where and when you drive." In Manitoba, when you drive is the big one.
Minus 25 and Short Trips
Natural Resources Canada's page on factors that affect fuel efficiency cites U.S. Environmental Protection Agency estimates that a drop in temperature from 24 to 7 degrees Celsius can increase fuel consumption in urban commutes by 12 to 28 percent. The same page says cold, dry winter air adds about 1.3 percent on the highway, and that a litre of winter gas typically has 1.5 to 3 percent less energy than a litre of summer gas. Minus 25 is a long way below 7 degrees, and that page gives no figure for it, so the honest way to know is to measure your own Grand Cherokee.
Remote Start and Idling
Remote start is a comfort on a minus 25 morning in Portage, and it is also idling. Natural Resources Canada says "Idling for more than 30 seconds has no benefit for the vehicle," and puts ten minutes of idling at 0.25 to 0.50 litres of fuel. By that figure, ten minutes on each of five workday mornings is 1.25 to 2.5 litres a week, our arithmetic, before the Grand Cherokee has moved. Run it the way your owner's manual directs, long enough to clear the glass, and drive gently while it warms.
A Block Heater on a Timer
Natural Resources Canada advises: "For best results, put your block heater on a timer, set to turn on no more than 2 hours before you start the engine." Use yours the way your vehicle's manufacturer directs. If your Grand Cherokee does not have one, our service department installs block heaters, and you can book a block heater installation.
Winter Tires and Tire Pressure
A change to winter tires can move your fuel number too, one more reason to measure in January. Pressure matters as well: Natural Resources Canada says tires under inflated by 56 kilopascals (8 psi) can increase fuel consumption by up to 4 percent. Cold air pulls pressure down, so check yours against the pressure on your vehicle's tire information label. We are a participating retailer in the MPI Winter Tire Program, and Manitoba Public Insurance sets who qualifies and which tires are eligible. Our service team can book your seasonal tire changeover.
A Roof Box on the Way to the Lake
July is not free either. A cargo box packed for a week at Clear Lake or in the Whiteshell sits right in the wind. Natural Resources Canada advises removing roof and bicycle racks when you are not using them, says aerodynamic drag can increase fuel consumption by as much as 20 percent on the highway, and notes that even empty, a permanent roof rack increases aerodynamic drag. It also says that at 120 km per hour, a vehicle uses about 20 percent more fuel than at 100 km per hour.
Pulling a boat or a camper changes the number again, and the ratings do not cover it. Our Grand Cherokee towing capacity guide covers what each engine is rated to tow; measure towing trips on their own, apart from your daily driving.
Measure Your Own Grand Cherokee
Fill the tank to the first click and reset the trip meter. At the next fill, divide the litres you put in by the kilometres on the trip meter and multiply by 100 for your L/100 km. Do it on two fill ups in January and two in July and compare the two averages. The difference is what a Manitoba winter costs your Grand Cherokee, on your roads, with your trips.
FAQs
What is the Jeep Grand Cherokee's fuel consumption in L/100 km?
From 10.4 to 11.3 L/100 km combined for the 2026 models, according to Natural Resources Canada. The 2.0 litre Hurricane 4 Turbo is rated at 10.4 in the two row Grand Cherokee and 10.7 in the Grand Cherokee L, and the 3.6 litre Pentastar V6 at 10.9 in the two row and 11.3 in the L.
Which Grand Cherokee engine uses less fuel?
The 2.0 litre Hurricane 4 Turbo, at 10.4 L/100 km combined in the 2026 two row Grand Cherokee against 10.9 for the 3.6 litre Pentastar V6, according to Natural Resources Canada. The gap is in the city, 11.5 against 12.3; on the highway both engines are rated at 9.2.
How many km per litre does a Jeep Grand Cherokee get?
About 9.6 km per litre at best, converting Natural Resources Canada's 10.4 L/100 km combined rating for the 2026 two row Grand Cherokee with the 2.0 litre Hurricane 4 Turbo. The 3.6 litre Pentastar V6 in the Grand Cherokee L works out to about 8.8. These are conversions, not separate ratings.
Is there a 2026 Grand Cherokee 4xe?
No. Jeep Canada's current Grand Cherokee pages list the 2.0 litre Hurricane 4 Turbo and the 3.6 litre Pentastar V6 only, and Natural Resources Canada's plug in hybrid file has no 2026 Grand Cherokee 4xe row. For a used 2025 Grand Cherokee 4xe, the file gives 4.2 Le/100 km combined on electricity, a 42 km electric range and 10.0 L/100 km combined on gasoline, and the 2022 to 2024 rows carry the same figures.
How much more fuel does a Grand Cherokee use in a Manitoba winter?
More, by an amount that depends on your trips, so measure your own. Natural Resources Canada, citing U.S. Environmental Protection Agency estimates, says a drop in temperature from 24 to 7 degrees Celsius can increase fuel consumption in urban commutes by 12 to 28 percent. Note the litres and kilometres over two fill ups in January and two in July, and compare the two averages.
The Bottom Line
Jeep Grand Cherokee fuel economy for 2026 runs from 10.4 to 11.3 L/100 km combined, about 9.6 to 8.8 km per litre by conversion, and the 2.0 litre Hurricane 4 Turbo in the two row is the efficient end. On the highway the engines tie; in town and in January, the Hurricane 4 Turbo and a light hand on remote start save fuel.
