2018 Jeep Wrangler Won’t go All Aluminum

Contrary to previous plans, the next-generation 2018 Jeep Wrangler will only use aluminum for some of its body panels. 

FCA has decided not to give the Wrangler a fully aluminum body and instead will use the lightweight material on the hood, tailgate and doors. “There will be a large portion of that vehicle that will be aluminum. It will not be all aluminum,” FCA CEO Sergio Marchionne said. “We’ve run the numbers and we’ve simulated mileage and the impact. Because of the difference in cost — not just of the material but the actual assembly process — I think we can do almost as well without doing it all-aluminum. I think we can get very close.”

Jeep is working to improve the Wrangler’s fuel economy and shedding weight is just one way to help with efficiency. The brand is also likely to introduce an eight-speed transmission to the Wrangler along with the possibility of the 3.0-liter diesel found in the Jeep Grand Cherokee.

The basics of the Wrangler, those being body-on-frame construction and solid axles, are expected to remain to keep the off-road crowd happy. Styling also won’t be a big departure from what we see today.

    Well that’s too bad. I wonder if Ford purchased ALL of the available aluminum for the F-150? Greedy pricks! Learn to share, LOL!

    lol

    Fail, Jeep. How about using a mix of high tensile steel and aluminum? I’m not sure I trust this “mystery material” code word for plastic, and a turbo four with a cvt? It works for the WRX.

  • The biggest weight problem with the JK isn’t the body, which is actually lighter than the TJ’s body because it uses a thinner steel (not to mention replacing a lot of the steel with plastic — the grill and fenders are now plastic), it’s the frame. They put pickup truck engineers to work designing the JK so it uses a tall heavy duty pickup truck frame rather than a traditional lightweight Jeep frame that required the transfer case belly skid and a fairly stiff belly pan to make it stiff enough. The goal was to give it a luxo ride with softer body mounts. Hello, we’re talking about a Jeep here, guys?

    still waiting for a hemi……

  • CloudClymer

    Fenders and body, frame and undercarriage will still rust.

  • Joe Totaro

    Not in TN! I’ve owned most of my Jeeps up North with the exception of a few years in FL…now looking forward to many years of rust-free Wranglers as a new Tennesseean!

  • Jerry Normandin

    YEAH.. but go light on the chassis and then you can’t take a Wrangler where you can take it now.

  • Jerry Normandin

    no cvt.. that would suck

  • Jerry Normandin

    an aluminum chassis will fail going off road where I go. and forget about rock climbing if you go with an aluminum frame. Diesel is the way to go.. lot’s of torque.

  • Jerry Normandin

    The 3.6L is actually not that bad. My 2013 was the only Wrangler I had that can go 0-60 in 6.8 seconds. If you don’t believe me check youtube!

    My commute changed so I had to trade it in while it was still worth money. I got a diesel TDI. If a wrangler with a diesel engine was available I would definitely get it.

  • Jerry Normandin

    Also Jeep didn’t even get the aluminum hinges on galvanized steel doors right. They didn’t use the correct primer.. so my hinges corroded due to a galvanic reaction. the engineers at Chrysler must have flunked chemistry.
    All they needed to do is use the same primer used on aluminum hull boats and it wouldn’t have corroded. I got aggrivated and my commute changed so I bought a VW 2.0L TDI. fast.. and 47mpg so far. But I can’t go off road. I am missing it now, it’s offroad time.

  • The TJ went everywhere the JK goes, and more because it has better clearance under its rockers and you can tuck its gas tank up higher with a body lift, unlike the JK. And the TJ did not have a tall pickup-style frame, it used the body to add the chassis stiffness to be a good offroader. The JK has its heavy frame to give a better ride to the passengers via softer body mounts. Period.

  • Jerry Normandin

    you should see where the fuel tank was on my 2013 JK. heavy frame for me was for rock climbing. and manuvering the washed out fire roads driving in and out of deep craters in 4WDL. I tell you I still wish I had a 72 International Scout. I was a teenager.. no license yet.. a friend and I took his father’s International Scout offroad since the road to the pipeline at the end of his yard.. man that was fun.

  • I have a JK and had a TJ. The only good thing about the JK is the 3.6L Pentastar engine and a much better automatic transmission behind that Pentastar. You cannot do radical gas tank mods like moving the gas tank into the cabin in California, BTW — you’ll fail smog. The emission system (of which the gas tank is a component) must be 100% stock in California. Which is why the fact that a frame rail is above the stock gas tank on the JK is so annoying — that keeps you from doing a body lift and tucking up the gas tank, which otherwise is a giant rock magnet on the bottom right side of your JK.

    2018 … so two more years? uhhh …For somer reason I thought the new Wrangler came out in 2017

  • HBO

    Yeah, I thought the same as you, 2017. Plus, they’ve been teasing us with this diesel thing for over a decade now. When I bought my ’06 LJ Ruby, there was talk of a diesel!

  • Sam Spade

    The Italians will having the Wrangler looking like a Fiat.

  • Stygimoloch

    If they put the V6 diesel in the Wrangler I would consider it ONLY if they put it with a manual transmission. None of that 8-speed auto crap.

  • Zat

    You are a very small percentage of jeep owners that will actaully take or modify it with the need for a heavier chassis. For 99% of buyers it wouldn’t be an issue either way.

    The best thing Jeep has done was leaving enough room under the hood for the LS-3, V-8 Chevrolet engine, and the Chevrolet 6l80e transmission. I had this combination installed by a company that has done their homework. When I can keep my foot out of it, it gets 20 MPG, and it passes the emissions test. I am so happy with this conversion, I’m sending my brand new Jeep out to get it’s 3.6 swapped. Thank you FCA for leaving the extra room
