Fuel economy numbers for the 2.0-liter four-cylinder powered Jeep Wrangler JL has been released by the Environmental Protection Agency (EPA), and it looks to deliver around 20% better fuel economy ratings than the standard V6 variants.

Those opting for the two-door model with an eight-speed automatic transmission will see a city fuel economy rating of 23 mpg and 25 mpg on highways for a combined rating of 24 mpg. The four-door Unlimited understandably returns lower fuel economy numbers at 22 mpg in the city and 24 mpg on the highway, resulting in a combined rating of 22 mpg.

Undoubtedly an improvement compared to the 3.6-liter V6, which gets 20 mpg combined when paired with the same automatic transmission. Fuel economy ratings drop to 19 for the manual Unlimited model. But turbocharged models require premium gasoline and annual fuel cost estimates by the EPA comes in at $2,100 for the two door and $2,300 for the Unlimited.

Aside from paying more for gas, the four-cylinder automatic combo costs an extra $1,000 over the V6 with an automatic transmission and $3,000 more than the standard model with a manual gearbox. On the bright side, you will be getting 270 horsepower and 295 pound-feet of torque on tap.

Pretty decent fuel economy figures considering the Wrangler is one of the least aerodynamically shaped vehicles aha. And I would guess that most owners will probably see numbers slightly lower than this, once they've got a lift kit and aftermarket tires equipped.

I have the mild hybrid turbo 4 . And using Regular Gas, the recommended gas is 91 octane , Driving 100 miles at 62MPH no air, windows closed , I got a real 26mpg. (27.5) in the gauges, on a mountian freeway. Not bad at all.

That's even more impressive when compared to the 18mpg that most people were getting in the JK. Always glad to see a new vehicle actually delivering on the EPA ratings.

how many miles have you put on it so far? I find that MPG numbers only really stick once you get well past the break in mileage.

So far 1700 miles and millage still keep going up.. Waiting for shoe to drop.. BTW the start stop on the tubo is almost totally seamless. Can't tell when engine is running, only light change when stops (for start stop). Then when you start up it is TOTALLY seamless. No annoying cranking of engine. Just goes.. The start stop on the 3.6 is nothing less then TOTALLY annoying. On the turbo, I actually want it to work

Start/stop tech has come a long way since it was first introduced, that's for sure. Look's like its been paying off in regards to the fuel savings that most owners are seeing.

We will probably see start/stop go by the wayside once full hybrid systems come in to play. FCA is going to have to find a way to drop weight to accommodate the additional battery/motor.

Sounds good to me, less trips to the dealer is always an incentive among all the other headaches these simplified powetrains bring with them.
Unfortunately it means when we do have issues, dealers are the only place to turn, no more independents.

Any new numbers on actual fuel economy. I’ve been wanting to get back into a Wrangler but have held out for the diesel but I’m about ready to give in and go with the turbo 4 or 3.6

2019 JL I-4 Mileage, 2000 Miles 50/city/50Highway

I have the i-4, and get 21-22 with a roof rack. I will tell you after having the JK for three years and getting 15-16 with a rack, even with premium fuel, the i-4 is a big improvement. Most notably up in the mountains, no power loss passing uphill at 7000'. If you want to see more you can check out the videos at CoolToysTV.com.
