2018 Jeep Wrangler owner’s manuals leaked, and they tell us much — but not all

If you're looking for some light reading to start your week, we have a suggestion for you. The " Owner's Manual" and the " User Guide" for the 2018 Jeep Wrangler have leaked, and have been posted on the JL Wrangler Forums. They appear to be the real deal. There's a ton of information, and many pages to pore over, but here's a little bit of what we've gleaned so far. The documents (assuming they're not just some very elaborate and convincing hoax) confirm the power sliding top, which is not removable, though the rear quarter windows are. We're not seeing any mention of a power soft top, though. There are instructions on door removal, as well as folding down the windshield. The manuals also confirm a 4WD Auto mode that shifts power between the front and rear axles as needed. What we don't appear to have yet are complete specifications. The manuals mention the 2.0-liter and 3.6-liter engines, but not their output figures. The 2.0-liter recommends premium fuel, while the 3.6-liter only needs 87 octane. Towing capacity for the two-door models is 2,000 pounds, while the four-door versions are capable of 3,500 pounds. The manuals also provide a lot of images, if you're interested in seeing the nitty gritty details of the Wrangler's various functions. Take a look, and make sure to post any interesting findings in the comments section, below. Related Video:

2018 Jeep Wrangler four-cylinder fuel economy revealed

Fuel economy numbers for the 2018 Jeep Wrangler with the turbocharged 2.0-liter four-cylinder have finally been announced by the EPA. In the city, the two-door model gets 23 mpg, and the four-door Unlimited gets 22. Highway fuel economy for the two-door is 25 mpg and 24 for the four-door. Combined for the two-door and four-door is 24 and 22 respectively. These aren't Prius numbers, but they do make the four-cylinder Wrangler the most efficient version of the off-roader so far. The rest of the Wrangler range with V6 power gets 20 mpg combined, with the exception of the manual four-door, which gets 19. The most efficient V6 models in the city are the automatic models, which, regardless of length, get 18 mpg. On the highway, the best V6 is the manual two-door, which manages 25 mpg, and only loses 1 mpg in the city to the automatic. The question is, is the improved fuel economy worth the price premium of the four-cylinder? The automatic-only four-cylinder engine is an extra $1,000 over a V6 automatic, and $3,000 over a V6 manual. And when looking at the annual fuel cost estimates at fueleconomy.gov, you might only save $50 to $100 each year. The problem being that, while it's more efficient, it also demands premium fuel that the V6 doesn't. So it could be quite a while before the upfront cost is recouped. But if you want a Wrangler that's a little nicer to the planet, it's probably the way to go, plus you get an extra 35 pound-feet of torque over the V6, even if it means sacrificing nearly 20 horsepower.

Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).
