Wrangler JL’s 8-Speed Gearbox Bumps Up Fuel Economy

8558 Views 6 Replies 5 Participants Last post by  Jeepernator


Jeep Wranglers aren’t known for being very fuel efficient and though the JL’s new optional 8-speed automatic transmission does make an improvement, it won’t be enough to satisfy the fuel conscious. For those who plans to purchase the new Wrangler JL either way, the Environmental Protection Agency has recently rated the gas V-6-powered Wrangler Unlimited for fuel economy.


The EPA is still lacking on information for the other Wranglers in the new JL lineup, but we do know that a JL Unlimited with a six-speed manual gearbox is rated at 19 mpg combined, 17 city and 23 highway. A slight increase compared to the 2017 model’s rating of 18/16/21. Similarly, the five-speed auto transmission’s rating will increase from 18/16/20 to 18/17/21 depending on the specs.

For those who want to optimize fuel economy, the new 8-speed automatic transmission is what you’d want to aim for. Compared to its predecessor’s five-speed automatic, this new gearbox is expected to return 20 mpg combined, 18 city and 23 on the highway. Though it may not look like much, this specification’s annual fuel cost is estimated to be $1,850.

Sure, some enthusiasts may proclaim that their not buying a Jeep for fuel economy, but a few hundred dollars in fuel savings could go towards a winch or trailer fund.

Wranglers are notorious for being gas guzzlers and people still buy them en-masse.
Gotta love how someone mentioned its solid front axle and only some heavy duty trucks from Ford and Ram, so in comparison the Wrangler JL's fuel economy is not that bad.
I've heard some reviews about Fuel Economy of Wranglers before and a lot of people saying that their actual fuel consumption wasn't even close to the numbers from the official report, it was less than that. So if you got disappointed about this news, you can check reviews of older Wranglers and see what people think about its gas consumption.
I assume most people know what they're getting into when it comes to Wranglers, they even look like gas guzzlers. If it's such a concern there's always the hybrid version that's coming out some time in the future, though I'm still not expecting amazing fuel economy numbers from those. On the bright side, the JL will most likely take 87 Octane gas so fill ups aren't going to cost an arm and a leg.

Part of that is because the Wrangler is in a way a lifestyle product and not anything anyone really needs. Of course the same can't be said for other SUV's and CUV's which just barely surpass what someone needs. So once someone gets into a Wrangler, its hard to get out. Not the greatest example but I see it like an iPhone user parting with their phone... it just won't happen, only under extreme conditions.
Completely agree with you. Wrangler is definitely a lifestyle product. I know one guy who has two Wranglers in his garage, one as a daily commuter, another for long trips and campings:D
The other one must be modded to the nines and get a good 15 mpg combined. :D
Once you go Wrangler, it'll be hard to go back to any other car unless you have a side sports car with weekend driving.
