What’s in the JL? Jeep tells us…

by David Zatz on

Yesterday, intrepid Allpar members discovered that FCA Canada had actually posted the 2018 Jeep Wrangler “JL” user’s guide on-line, with no password or security of any kind.

That’s now made its way across the Internet, showing some of the new features of the iconic off-road vehicle — which is very popular in cities and suburbs as well.

Buyers can now get paddle shifters (a useful feature for off-roading), a keyless entry with a pushbutton start, a power sliding top, and safety/convenience features such as blind spot monitors, rear cross path, and parking sensors.  The full time four wheel drive system will use a five-position transfer case.

The power sliding top, with removable rear quarter windows, was explained on page 147; the new cargo rail organizer, on page 155; and the ability to program auxiliary switches — a big deal on what may be the most commonly customized vehicle sold — is on page 170.

On the electronics side, just as powerful Dodges have special pages on their 8.4 inch screens for performance settings and readouts, Wrangler buyers can see off-road pages that show pitch and roll, graphically and numerically, along with the latitude, longitude, altitude, and four wheel drive status; or the steering angle, sway bar and axle status, and other details.

Moving with the times, Jeep also provides Type C USB ports, rather than the older kind installed on most cars.  The UConnect 4 system goes up to a seven-inch screen; and the optional instrument cluster appears to have a seven-inch customizable center screen (the base cluster has a large, but more traditional, trip computer in the center).

The company all but confirmed the Hurricane 2-liter turbo four, by including photos of it in the manual — which was posted on Saturday night in the Allpar forums, by reader UN4GTBL.  The four-cylinder can run on regular gas, but, not surprisingly, prefers 91 octane. Both engines can handle up to 15% ethanol, just in case Congress goes back to pushing it.

Actually, there are two Hurricane options — one with a belt-starter-generator unit, and one without. The BSG is used for efficient stop-starts (the engine shuts off when not needed, e.g. at a traffic light, and immediately restarts when needed).

Automatic stop/start systems are now available on some models, with manual transmissions. The system automatically restarts the engine when the driver pushes down the clutch, and can be disabled for off-road driving.

Towing weights range up to 3,500 pounds (four-door; the two-door is 2,000 pounds).  The gross combined weight rating is 8,016 pounds for the two-door, 8,117 for the four-door.

If all that isn’t enough — there’s a new key fob.
