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.

NHTSA upgrading Jeep Grand Cherokee, Dodge Durango headliner fire probe

The National Highway Traffic Safety Administration investigation into headliner fires experienced by a small number of Jeep Grand Cherokee and Dodge Durango owners has been upgraded to an engineering analysis, the step before the initiation of a recall. In August last year the investigation began with 146,000 Grand Cherokees from 2012 after three complaints were received, but a report on Edmunds says it has been expanded to include 593,299 vehicles covering the 2011-2013 model years for the Jeep and the Dodge Durango, which uses the same headliner assembly, because of possibly 52 incidents of fire.
In some of those incidents drivers have reported a burning odor, smoke or open flames that were contained to the headliner or migrated to another area of the passenger compartment. The culprit has apparently been found: NHTSA blaming an electrical short in the sun visor vanity light wiring, which is routed under the headliner and held in place by three screws. Chrysler began its own probe into the issue when it was first reported and is still looking into the situation while, "fully supporting the National Highway Traffic Safety Administration's investigation."

Jeep reveals annual Moab Easter Jeep Safari concepts

Jeep has unveiled its annual spate of concepts before the Easter Jeep Safari. Those start with the Grand Cherokee Trailhawk Concept (below left), complete with the company's EcoDiesel V6 engine. Designers threw in a set of 35-inch Mickey Thompson tires wrapped around 17-inch Rubicon wheels, and a set of custom fender flares help keep all that rubber under wraps.
Meanwhile, the Wrangler Mopar Recon (below right) packs a 6.4-liter Hemi V8 good for 470 horsepower. All that grunt gets to the ground via a five-speed automatic transmission and a set of a Dana 60 axles frond and rear with 4.10 gears. The Recon also makes use of a 4.5-inch prototype long-arm kit and a set of prototype eight-lug bead lock wheels.
The Wrangler Stitch (below left) builds on the momentum of the Wrangler Pork Chop Concept. Engineers once again set out to strike as much weight as possible from the vehicle, and actually managed to trim the curb weight down to 3,000 pounds. That effort has given the machine the same power to weight ratio as the Grand Cherokee SRT8. Plenty of carbon fiber, door deletes and a chrome moly roll cage all help trim those pounds, and a set of DanyTrac Pro Rock 44 axles with 4.88 gears and ARB lockers front and rear let this machine scramble over whatever is in its path.
