2015 Jeep Renegade Trailhawk [w/video]

There are two avenues to the world of off-roading. Arguably the more popular is to pick up a second- or third-hand Jeep, Land Rover or pickup truck and go wild with the aftermarket. The opposite approach, though, is to simply buy new, which brings a warranty along with the most up-to-date off-road tech fitted by the factory (despite likely lacking the ultimate capability of an aftermarket-imbued vehicle). That second option has, traditionally, been pricey. Take our long-term Jeep Cherokee Trailhawk, which rings up at just over $38,000. A Ford F-150 SVT Raptor is going to be an even more expensive proposition, while the undisputed kings of luxury off-road performance from the factory – the Range Rover, Toyota Land Cruiser and Mercedes-Benz G-Wagen – will require ownership of a medium-sized oil well. With all due respect to those who take their Trail-Rated Jeep Patriot models off-road, the all-new Renegade Trailhawk is such an exciting proposition because it brings the cost of a warranty-backed off-roader down significantly, while also delivering a degree of trail-rated performance that should easily fulfill the needs of the average enthusiast. Drive Notes Before we get into what it adds, it's worth noting that the Trailhawk trim does have a small impact on the Renegade's on-road abilities. As we said in our original feature, the TH adds a significant amount of weight to the standard CUV, as it tips the scales at nearly 3,600 pounds. That mass, combined with the slightly higher stance, means the off-road model doesn't handle quite as well as a lesser Jeep. It also doesn't feel as fleet of foot, as it retains the same 2.4-liter, 180-horsepower four-cylinder and nine-speed automatic found throughout the Renegade range. Despite the downers, the Trailhawk trim does bring quite a lot to the Renegade package, most notably in the form of a bespoke version of Jeep's Active Drive all-wheel-drive system. The upgraded system features a dedicated 20:1 crawl ratio while the Selec-Terrain system is home to a new Rock setting. Beyond that, Jeep lifted the Renegade's ride height eight-tenths of an inch, increasing overall ground clearance to 8.7 inches and delivering 8.1 inches of wheel articulation. This is complemented by unique front- and rear-fascias, which up the approach and departure angles to 30.5 and 34.3 degrees, respectively, besting the Cherokee Trailhawk's 29.8 degrees and 32.1 degrees.

Jeep Cherokee faces on-sale delay

A report in The Wall Street Journal looks at some of the obstacles to the 2014 Jeep Cherokee that go beyond its mootable yet "very contemporary" looks, almost all of them based on Fiat's financial position. Starting with that sheetmetal, in defense of it SRT president Ralph Gilles and Jeep design head Mark Allen said they wanted to "make sure the design still looks modern five years from now."
The WSJ piece doesn't cite longevity as a factor, instead saying that its features originated in a design for an Alfa Romeo, the transformation into a Jeep design meant allowing Chrysler get it to market more quickly and save "hundreds of millions of dollars" in engineering.
The need for Fiat to save money while it weathers the European situation has cut budgets for development, engineering and the pace of retooling the Toledo, Ohio plant to build the Cherokee. In a familiar case of snowballing at work, among the effects will be pushing back the Cherokee's volume sales date and delaying updates to some of Chrysler's other products.

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.
