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.

Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

2014 Jeep Cherokee starting price set at $22,995*

Love it or hate it, the 2014 Cherokee is on its way to a Jeep showroom near you this fall. Today, Chrysler announced the different trim levels, features and pricing for its new compact utility with a starting price of $22,995 (*not including $995 for destination), which is $400 less than the 2012 Liberty it ostensibly replaces.
Available in four trim levels - Sport, Latitude, Limited and Trailhawk - the new Cherokee will come standard with Chrysler's 2.4-liter Tigershark inline four-cylinder engine with the upper three levels offering the option of the company's 3.2-liter Pentastar V6. The base Sport is your typical entry-level model, featuring equipment including manual cloth seats and black exterior mirrors and door handles, but it also has a five-inch Uconnect media center, LED taillights and 10 standard airbags. Stepping up from the Sport model, Latitude and Limited trims bring increasing levels of luxury starting at $24,495 and $27,995, respectively. All three of these trims are front-wheel drive in standard configuration and offer varying versions of Jeep's Active Drive four-wheel-drive system.
The range-topping $29,495 Cherokee Trailhawk (shown above) comes standard with four-wheel drive and numerous upgrades to earn Jeep's Trail Rated fender badge. These changes include a unique design that adds an off-road suspension with taller ride height giving more aggressive approach and departure angles, underbody skid plates, distinguishing exterior design elements and a seven-inch, reconfigurable instrument gauge cluster similar to what it found in high-trim Dodge Dart models.
