Fiat Chrysler can’t keep the cat in the bag with its upcoming 2018 Jeep Wrangler JL. The latest leak is massive in scale, unloading details of trim packages, paint colors, and order codes, complete with all their corresponding options. The info comes straight from FCA’s online dealership ordering system via the fan forum JLWranglerForums. Image screenshots confirm the authenticity while giving an unprecedented glimpse at what Jeep’s internal operations. This leaves only the final design, engine output specs, and MSRP to speculation. But with the Wrangler’s debut scheduled for the LA Auto Show in November, there’s still plenty of time for more leaks.

Leading this batch of leaks is the addition of a power-retractable soft top, the conformation of the 2.0-liter four-cylinder and 3.0-liter EcoDiesel V-6, the axing of the luxury-minded Sahara trim for the two-door Wrangler, and the debut of a full-time 4WD system reserved exclusively for the four-door Sahara. Jeep purists shouldn’t fret, though – the Sport and Rubicon trims return, along with an optional Heavy Duty Electrical Group (supposedly for running extra lights and a CB radio), and something called the “Trail Rail Management System.” Six tire and four wheel options are present, too, with wheels sized at 17 and 18 inches. Seven color choices will be offered, along with the return of a tan soft top. The AEK Electronic Infotainment System Group includes Apple CarPlay and Android Auto, and Alpine returns as the premium audio system.

Powertrain News

Aside from the stuff already mentioned, the most important news from this leak is the confirmation of the 2018 Jeep Wrangler JL’s powertrain lineup. The 2.0-liter “Hurricane” four-cylinder turbo will be the base engine. It will come with a Belt Starter Generator, which means it will have an Automatic Start/Stop system for increased fuel economy. The mid-range (and likely volume-leading) engine will be the 3.6-liter Pentastar V-6, while the 3.0-liter EcoDiesel V-6 will be the range-topping choice. Transmission options are a six-speed manual and the ZF eight-speed automatic.

As for the new full-time 4WD system, it’s called Selec-Trac. If that name sounds familiar, it’s because Jeep has used the name before. Launched in 1983, various Jeep models used the full-time system. A newer version called the Selec-Trac II came out with the 2008 Jeep Liberty and featured a 2.72:1 4WD Low Range. In addition to an Automatic mode, the transfer case could be set to 2WD (for fuel savings), Neutral, and 4WD Low. Nothing is known about the new 2018 Wrangler’s Selec-Trac transfer case besides two key points: One, it will obviously have an automatic 4WD mode that engages the front axle when the rear axle begins to lose traction, and two, it will share the 2.72:1 4WD Low Range gear ratio with the previous Selec-Trac system.

Color Choices

The 2018 Wrangler will be available in seven colors, though it’s unknown if any colors will be limited to specific trims. The colors are: Granite Crystal Metallic, Acid Yellow, Firecracker Red, Billet Silver Metallic, Bright White, Black, and Nacho. Interestingly, JLWranglerForums says Light Green and Blue were mentioned at an FCA dealership meeting, suggesting these two colors could make the list by the beginning of production.

RPO Codes Galore!

Ah the ambiguous yet all-important barrage of RPO codes used by the automaker and fanboys alike. (Who doesn’t love talking in a secret code?) The 2018 Wrangler JL will come with plenty of options. The dealership order guide lists each of these, along with their official Regular Production Code.

The list of main option packages includes the Technology Group, LED Lighting Group, Convenience Group, Cold Weather Group, heavy Duty Electrical Group, Electron Infotainment System Group, Dual Top Group, Safety Group, Steel Bumper Group, and Smoker’s Group. As always, not every option package will be offered with each trim level and some option packages will come standard with certain trims. Starting off, the 2018 Wrangler will come in the Sport, Sahara, and Rubicon trims.

Interior options include the Mopar High Headliner, Trail Rail Management System, all-weather floor mats, a soft top window storage bag, air conditioning, Alpine premium Audo, Google Android Auto, Apple CarPlay, SiriusXM satellite Radio, and the Jeep Trail Rated Kit (which includes a tow strap, gloves, and other tools).

Exterior options include deep tint sunscreen windows, power-heated mirrors, steel front bumper, body color fender flare, and tubular side steps. As for the Jeep’s tops, the options include the three-piece hard top in either black or body color, the Premium Sunrider Soft Top in either black or tan, a (non-Sunrider) Premium Soft top in either black or tan, and a Black Power Soft Top.

Tire choices will be limited to trim levels, but the full list includes one All-Season tire option sized at 245/75R17 and four All-Terrain tires in the following sizes: 255/70R18, 245/75R17, 255/70R18, and 245/75R17. Reserved for the hard-core Wrangler Rubicon is an Outlined White Letter Off-Road tire sized at LT285/75R17 – or otherwise a 33.8-inch-tall tire. That’s slightly larger than the BFGoodrich Mud-Terrain KM tires on the current Wrangler JK Rubicon. Wheel choices include a 17-inch Polished Granite Crystal wheel, a 17-inch Tech Silver Aluminum wheel, a 17-inch Black Wheel with a Polished Lip, and an 18-inch Tech Gray Polished Face wheel. All wheels measure 7.5 inches wide.

Mechanical options beside the engine and transmission include the following: the new Selec-Trac Full Time 4WD System with a 2.72:1 gear ratio, an Anti-Spin rear differential, remote proximity keyless entry, remote keyless entry, Remote start, and an engine block heater.

Conclusion

Boy, more is known about the 2018 Jeep Wrangler than anyone ever expected before its release. This level of detail has even been absent from vehicles after their debut. Take the 2017 Ford GT, for example. While unusual, the advanced notice helps fuel the anticipation for Jeep’s reinvented icon model. Of course, we expect Jeep to come clean on all the juicy details at the Wrangler JL’s debut at the 2017 LA Auto Show in November. Until then, stay tuned to TopSpeed. You never know – Jeep might just give up and release the 2018 Wrangler JL ahead of its official debut.
