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.

Jeep Cherokee sales rival Wrangler after two months

In our First Drive article on the 2014 Jeep Cherokee we said, "our informal and thoroughly unscientific opinion is they're going to sell tons of them. Why? Because it is very good." So far, it appears the public concurs. Of course, it's very early - the new compact utility has logged just one month of confirmed sales, but Larry Vellequette at Automotive News says dealers have told him that the second month of sales will be even better, a message that mirrors what we've heard from company execs.
In its first, severely truncated month on sale, the Cherokee sold 579 units. With all of November to play with, though, dealers moved 10,169 of them - compared to 11,753 Wranglers and 14,798 Grand Cherokees. That helped propel Jeep to a 30-percent year-on-year improvement for the month, Chrysler Group to a 16-percent improvement and the group's 44th consecutive month of sales growth, exceeding analyst expectations in posting its best November numbers since 2007.
If it can just keep replicating the its first month of sales, the finalist in North American Truck of the Year voting will smoke the trade done by the outgoing Liberty, which didn't break 7,900 units in a month in the last four years of its life (and normally didn't get close to even that). In March this year, Chrysler said it wants to build 250,000 Cherokees in its Toledo assembly plant for global sales. It's early yet, but with second-month sales quoted as being as "strong as death," the bookies might be resetting the odds.

Jeep Grand Cherokee SRT gets power increase, minor tweaks for 2015

As a brand within Fiat Chrysler Automobiles, SRT may have an uncertain future, but it's pumping out some seriously mean machines anyway. The supercharged Hellcat V8 may be gobbling up most of the headlines with its 707 horsepower, but even the Grand Cherokee SRT is getting some small updates for the 2015 model year.
Most importantly for many enthusiasts, the Grand Cherokee SRT is getting a slight power bump. Don't expect the 700+ hp from the Hellcat, but this SUV sees a modest 5-hp and 5-pound-feet of torque improvement to bring output to 475 hp and 470 lb-ft for its 6.4-liter V8 with an eight-speed automatic. The minor change doesn't change the sprint to 60 miles per hour, clocking in at the same 4.8 seconds, or the tow rating at 7,200 pounds. Still, more grunt is never a bad idea.
Another new addition is the Active Noise Canceling system as a standard feature for this powerful SUV. It adds four microphones around the vehicle and uses the stereo system to nullify extraneous sound. However, Jeep claims that the meaty exhaust note from the V8 still gets through into the cabin for driver enjoyment.
