2018 Jeep Wrangler will have an aluminum hood and doors, leaked memo says

Earlier this year, FCA CEO Sergio Marchionne revealed that 2018 Jeep Wrangler would feature a heavy dose of aluminum, though he didn't specify how. Now, JL Wrangler Forums says the Wrangler will use the material for the hood and the doors, citing an internal bulletin from aluminum supplier Alcoa. According to the forum, the company says the next-gen Wrangler will utilize Aloca's C6A1 (an internal name) high form alloy. The SUV will also get 6022 and A951 from Alcoa that will be used on the SUV's front and rear doors, as well as for the hood. Alcoa's C6A1 is the company's new high form alloy, while its 6022 alloy sheet can be found on things like a car's hood, door, or closure panels. Alcoa's A951 is the company's pre-treatment aluminum sheet bonding technology that it uses on automobiles. "A team in the Farmington Hills (Michigan, USA) Aerospace and Automotive Products group is leading a new profitable growth opportunity with the 2018 Jeep Wrangler program. The next generation Jeep becomes the first to utilize our C6A1 high form alloy; we are currently the only supplier of this high form product. Alcoa will also supply 6022 and A951, including front and rear door inners, hood outer and inner." As Marchionne pointed out earlier this year, the 2018 Wrangler won't be made entirely out of aluminum. So Alcoa's contribution to the upcoming SUV's doors and hood could be the only components that use the lightweight metal – or Jeep could be using another aluminum supplier for other parts. Large changes lie ahead for the 2018 Wrangler, which include a pickup version, new engines, and aluminum. But we do know that the next Wrangler is that it will be built in Toledo, OH, as FCA announced plans to spend $1.05 billion to retool the Wrangler factory, while also adding another site in Illinois earlier this year.

Buy this instead of a Wrangler | 2017 Jeep Grand Cherokee Trailhawk Review

In our first encounter with the 2017 Jeep Grand Cherokee Trailhawk at Fiat Chrysler's Chelsea Proving Grounds, we saluted the new model's impressive on-road demeanor. In its off-road mode, however, we couldn't ignore the pre-production throttle calibration – it was super sharp and difficult to modulate with the precision needed to navigate obstacles. We were told then that Jeep's engineers were aware of the problem and were fixing it for production models. So we recently set off for Bundy Hill Off-Road Park in Jerome, Michigan, in a production-spec Grand Cherokee Trailhawk to check their work and get a better idea of the overall package. We can report that the Trailhawk's throttle has been fixed for production, landing it properly in Goldilocks territory. In the off-road Mud setting, the throttle is soft and easy to modulate. You can balance this rig with the gas pedal, reaching just past tip-in to steadily prod forward. But the gas pedal doesn't delay when you really need power. Move beyond the initial tip-in, and the engine responds quickly, which is a good thing, as a sluggish throttle is almost as dangerous off-road as one that's too sharp. Rock mode promises even more precise control over the throttle, although our lack of a spotter and a desire to avoid damaging the 700-mile-young Trailhawk kept us from hitting Bundy Hill's rockier sections. The wet, non-snowy weather meant we didn't properly test Snow or Sand mode. This test model was equipped with FCA's popular 3.6-liter V6, but like the rest of the Grand Cherokee range, more power is available from the 3.0-liter EcoDiesel V6 and the 5.7-liter Hemi V8. You don't need them – the 3.6-liter and eight-speed automatic are perfectly fine on the trails. Faced with an incline, the transmission holds its gear without complaint – you don't even need to switch into manual mode. Despite the 4,800-rpm torque peak, the V6's 260 pound-feet arrive early enough that you don't need to strong-arm the throttle. So that's resolution for the pre-production issue. But our time at Bundy Hill exposed a different and ultimately much easier to fix problem for the production model. Late fall in Michigan is not always a good time to go off-road – sub-40-degree temperatures and a steady, depressing drizzle can turn a relatively simple trail into a slippery mess of wet clay. Conditions like these can easily overwhelm an on-road tire like the Goodyear All-Terrain Adventures the Trailhawk uses.

What to see at the Detroit Auto Show 2023

The 2023 North American Auto Show — also known as the Detroit Auto Show — is underway downtown. If you want to attend the public days of the show taking place September 16-24, hereÂ’s what you need to know about attending. But now that Autoblog has done our reconnaissance during the showÂ’s press days, we can tell you about the actual cars (and other things) you can see and experience. WhatÂ’s new? Ford The big new item from Ford is the 2024 F-150 pickup. You can check out the new trick tailgate, and see what the fuss is all about. The 2024 F-150 Raptor also debuted at the show, if you like high-power, off-roady full-size pickups. The show will also be a good opportunity to see the Mustang Dark Horse and Mustang Mach-E Rally up close and personal. Unfortunately, we only saw the wild 2025 Mustang GTD at an offsite event during press days, but it's quite possible Ford will roll it out for the public. Cadillac Cadillac revealed its refreshed 2025 CT5 at the Detroit show, and you can get a look at the revised front and the new tech-focused interior. Cadillac recently unveiled the all-electric 2025 Escalade IQ, so you can stop and see the most powerful Escalade ever while youÂ’re there. It wasnÂ’t on the floor during media days, but Cadillac told us theyÂ’d bring it for the public part of the show. Jeep Jeep unveiled its 2024 Gladiator at the show, and you can check out the new interior and trim levels in person at the Jeep stand. Jeep also has an indoor track set up for ride-alongs. If you havenÂ’t had the chance to see the refreshed 2024 Wrangler yet, you can see that, too, along with examples from the rest of the Jeep lineup, along with its Stellantis sibling, Ram. GMC GMC showed off the new, larger 2024 Acadia SUV for the Detroit Auto Show. ItÂ’s bigger than before, but does more to differentiate itself from its Chevy cousin, the Traverse. GMC also has its Sierra EV on display if youÂ’re interested in catching that in person. What else to see A number of automakers have large displays at the show with many of their models represented. In addition to those who debuted something new at the show, Buick, Chevrolet (check out the Silverado, Blazer and Equinox EVs, as well as the Corvette E-Ray), Lincoln with the new Nautilus, Toyota (get a look at the new Tacoma), Volkswagen, Honda, Kia, Hyundai, Mini, Volkswagen, Honda, Chrysler (the Airflow concept is there), Fiat, Ram and Dodge (see the Charger Daytona SRT concept) all have a sizable presence.
