Partial Next-generation Jeep Wrangler Engine Specs Leaked? [UPDATED]

partial next generation jeep wrangler engine specs leaked updated

Our resident document digger, Bozi Tatarevic, stumbled upon a document submitted to the National Highway Traffic Safety Administration that may confirm at least some details about the next Jeep Wrangler.

The docs appear to confirm that the upcoming JL-platform Wrangler will offer two engines at launch – a 3.6-liter V6 that makes 285 horsepower and a turbocharged 2.0-liter four-cylinder that makes 368 horsepower. Yes, you read that right.

The other piece of news gleaned from the submitted docs is that the Wrangler will initially debut as four-door only. Just three trim levels were listed: Sport Unlimited, Sahara Unlimited, and Rubicon Unlimited.

Don’t worry, Wrangler fans. Just because a two-door bodystyle isn’t listed, it doesn’t mean it’s not happening (as seen by this diesel-engine option or the pickup-truck bodystyle, which Jeep has confirmed.

We’ve already reported that the diesel is still a go, and that it will appear later on, probably in the spring of 2018. We’ve also already reported that the truck version will bring back the Scrambler name and go on sale in 2019.

These documents appear to confirm some other bits of our previous reporting – we already wrote about leaks that indicate a production run beginning in November with the four-door hardtop bodystyle and a choice of engines between the 3.6-liter V6 and 2.0-liter turbo four.

We also reported the V6 would be offered with an eight-speed automatic transmission or six-speed manual and that the 2.0-liter would be a “ mild hybrid” unit only offered with an automatic. The docs do not confirm anything related to transmissions, nor do they confirm or refute the “mild hybrid” reporting. It’s entirely possible that Jeep could offer a traditional turbo four and a mild hybrid, or that the turbo four is a mild hybrid.

Roof options are likewise not touched upon, nor is the type of 4WD system offered, although the docs do show there will be 4WD of some sort, as one would expect from a Wrangler.

I reached out to Chrysler for comment, and got the usual response, which is to say that Chrysler PR folks won’t talk about future product. I was unable to confirm whether the Wrangler would debut at the Los Angeles Auto Show in November – which it would if the production run does, in fact, start next month – or at FCA’s hometown auto show, the North American International Auto Show, which takes place in January.

Personally, I’d love to see a manual transmission matched to the 2.0-liter, but whatever the case is, the wraps will be off the package soon.

You can read the documents for yourself below.

UPDATE, 10/12/2017: As noted by our own Steph Willems, FCA has refiled the documentation, and the 368 figure has been replaced with an unrated number. Click here for more.

    At least now we know how to email or call Rhonda Curran, so we can find out if the 368HP 2.0 turbo is a typo or the real deal.

  • Jim Bonham Full EVs are not for everyone, they cannot meet all needs. Hybrids do a much better job of providing the benefits of EVs without most of the drawbacks. I have a hybrid sedan with plenty of room, plus all the bells and whistles. It has 360 hp, AWD, does 0-60 in just over 5 sec.(the instant torque is a real benefit), and I get 29 mpg, average. NOT driven lightly. I bought it used for $25k.Sure, it's a little heavier because of the battery, motor, etc., but not nearly as much as a full EV. The battery is smaller/lighter/cheaper and both the alternator and starter motor are eliminated since the motor assumes those functions. It's cool to watch the charge guage show I'm getting energy back when coasting and/or braking. It's even cooler to drive around part of the time on battery only. It really comes in handy in traffic since the engine turns off and you don't waste fuel idling. With the adaptive cruise control you just let the car slowly inch along by itself.I only wish it were a Plug-in Hybrid (PHEV). Then, I'd have A LOT more EV-only range, along with even more of that instant torque. The battery would be bigger, but still a fraction of the size of a full EV. I could easily go weeks without using much, if any gas (depending upon my commute) IF I plug it in every night. But I don't have to. The gas engine will charge the battery whenever it's needed.It's just not as efficient a way to do it.Electric companies offer special rates for both EVs and PHEVs which lower your operating cost compared to gasoline. They'll even give you a rebate to offset the cost of installing a home charger. You can still get federal (up to $7,500, plus some state) tax credits for PHEVs.What's not to like? My next daily driver will be a PHEV of some kind. Probably a performance-oriented one like the new Dodge Hornet or one of the German Hybrid SUVs. All the benefits, sound, feel, etc., of a gas vehicle along with some electric assist to improve fuel economy, performance, and drivability. None of the inherent EV issues of cost, range anxiety, long charging times, poor charger availability, grid capacity issues, etc. I think most people will eventually catch on to this and go PHEV instead of going full EV. Synthetic, carbon-neutral eFuels, hydrogen engines, and other things will also prevent full EVs from being 100% of the fleet, regardless of what the politicians say. PHEVs can be as "clean" (overall) as full EVs with the right fuels. They're also cheaper, and far more practical, for most people. They can do it all, EVs can't.
