2016 Jeep Wrangler to ditch solid axles to save weight?

Hey, Jeep fans. If you think the idea of a funky-looking, car-based Cherokee revival is offensive, have a listen to what might be in store for the next-gen Jeep Wrangler. Automotive News is reporting that as Jeep develops the 2016 Wrangler, weight reduction is a crucial target, and the Wrangler's rugged solid axles could be sacrificed in the name of better fuel economy.
We've already heard the next Wrangler will go on a serious diet using aluminum body panels and an air suspension system, so the idea of a four-wheel independent suspension setup for this OG SUV isn't all that surprising. Besides, it's not like an independent suspension would limit the Wrangler's off-road abilities - just check out the Hummer H1. In fact, it might be the aftermarket parts companies - not Wrangler enthusiasts - who would be most disappointed by such a drastic suspension change, as the article states that the Wrangler's solid axles and coil-link suspension make it the most popular SUV for customization.
There are probably still a couple years before we'll start hearing any concrete details about the 2016 Wrangler, at which time it will be interesting to see how stricter fuel economy and crash safety regulations have been balanced with traditional Wrangler cues like its removable doors and roof and folding windshield. Let us know in the comments below if a Wrangler sans solid axles is any less of a Wrangler.

Jeep in St. Louis hacked from Pittsburgh

One of America's most popular vehicles contains a security flaw that allows hackers to remotely commandeer it from anywhere on the planet. Cyber-security researchers Chris Valasek and Charlie Miller say they've accessed critical vehicle controls on a 2014 Jeep Cherokee that allowed them to remotely control critical vehicle functions like braking, transmission function, and steering. Automakers have downplayed the possibility a car could be remotely compromised, but the significance of the findings detailed Tuesday could cause them to reevaluate the threats posed to hundreds of thousands of vehicles already on the road. A key finding – the pair needed no physical access to the Jeep to pull off the attack. Valasek and Miller accessed the controls via a security hole in the Sprint cellular connection to Chrysler's UConnect infotainment system. In the course of their research, Valasek sat in his Pittsburgh home and remotely manipulated Miller's Jeep as he drove along a highway outside St. Louis. If you know a car's IP address, they say, a hacker could control it from anywhere. "We didn't add anything, didn't touch it," Valasek told Autoblog. "A customer could drive one of these things off a lot, and they'd have no clue it had these open attack surfaces." Remotely, he disabled brakes, turned the radio volume up, engaged windshield wipers and tampered with the transmission. Further, they could conduct surveillance on the Jeep, measuring its speed and tracking its whereabouts. They conducted the experiments over multiple breaches. They made their findings public on the same day the National Highway Traffic Safety Administration, the federal agency in charge of vehicle safety, released its latest report on the readiness of government and automakers to fend off these sorts of cyber attacks. Later today, two US Senators are expected to introduce legislation that would help consumers better understand the potential risks of car hacking. In the early stages of their research, Valasek and Miller found a security flaw in the car's wi-fi that allowed them to remotely manipulate controls from a range of about three feet. But in recent months, they found another vulnerability in the Sprint cellular connection in the UConnect system. That was a key breakthrough. "Lo and behold, we found we could communicate with this thing using cellular, and then more research, and 'Holy cow,' we're using the Sprint network to communicate with these vehicles," Valasek said.

2019 Jeep Cherokee First Drive Review | Still the most truck-like crossover SUV

The history of the SUV has been one of ever-increasing refinement, and that arc bends towards carlike forms. It's a trend that even the hardiest of nameplates has succumbed to, including the venerable Cherokee, which for 2014, moved from the solid-axle brick of yore to the shark-nosed, independently suspended crossover of modern-day. That wasn't necessarily a bad thing. We found it to be quite a competitive machine at the time, and one that was plenty capable. But time marches on, and five model years later, Jeep has updated the Cherokee. The polarizing shark nose has been toned down, with all the headlight elements integrated into single units on either side. The hatchback has been revised and now sports a cutout for the license plate. Besides improving the looks at the back, Jeep says it allowed them to expand the rear cargo area to 25.8 cubic feet, an increase of 1.2 cubes, because moving the license plate space allowed them to pull the latch assembly farther out. It should be noted, though, that the Cherokee still doesn't have as much cargo capacity as the new 27.2-cubic-foot Compass. Besides the cosmetic changes, the new Cherokee gets a new engine, a 2.0-liter turbocharged four-cylinder good for 270 horsepower and 295 pound-feet of torque that shares commonality with the Jeep Wrangler and Alfa Romeo Giulia engines. However, it lacks the mild hybrid technology of the Wrangler because of space issues, and it has a cylinder head with two camshafts rather than the Alfa's single-overhead cam design. In addition to the new 2.0-liter turbocharged engine, the Cherokee's old naturally aspirated engines, a 2.4-liter four-cylinder (180 hp, 170 lb-ft) and a 3.2-liter V6 (271 hp, 239 lb-ft), carryover unchanged except for the addition of standard engine start-stop functionality. The question is, can mild changes to the Cherokee keep it competitive in a segment where several rivals have been completely redesigned? In terms of capability, the answer is a resounding, "yes," particularly for the Trailhawk, which in turbocharged guise, has even shorter gearing for its low-range four-wheel-drive setting than before at 51.2:1. Like the previous model, the Trailhawk includes different front and rear bumpers for improved clearance and approach and departure angles. It features a set of skid plates and gets a steel oil pan for protection from obstacles, and the rear axle can be locked for additional traction.
