Feds fretting over remote hack of Jeep Cherokee

A cyber-security gap that allowed for the remote hacking of a Jeep Cherokee has federal officials concerned. An associate administrator with the National Highway Traffic Safety Administration said Thursday that news of the breach conducted by researchers Chris Valasek and Charlie Miller had "floated around the entire federal government." "The Homeland Security folks sent out broadcasts that, 'Here's an issue that needs to be addressed,'" said Nathaniel Beuse, an associate administrator with the National Highway Traffic Safety Administration. Valasek and Miller commandeered remote control of the Cherokee through a security flaw in the cellular connection to the car's Uconnect infotainment system. From his Pittsburgh home, Valasek manipulated critical safety inputs, such as transmission function, on Miller's Jeep as he drove along a highway near St. Louis, MO. The scope of the remote breach is believed to be the first of its kind. The prominent cyber-security researchers needed no prior access to the vehicle to perform the hack, and the scope of the remote breach is believed to be the first of its kind. A NHTSA spokesperson said the agency's cyber-security staff members are "putting their expertise to work assessing this threat and the response, and we will take action if we determine it's necessary to protect safety." A Homeland Security spokesperson referred questions about the hack to Chrysler. Fiat Chrysler Automobiles has already been the subject of a federal hearing this month, in which officials scrutinized whether the company had adequately fixed recalled vehicles and repeatedly failed to notify the government about defects. But cyber-security concerns are a new and different species for the regulatory agency. Only hours before the Jeep hack was announced by Wired magazine earlier this week, NHTSA administrator Dr. Mark Rosekind said hacking vulnerabilities were a threat to privacy, safety, and the public's trust with new connected and autonomous technologies that allow vehicles to communicate. NHTSA outlined its response to the cyber-security challenges facing the industry in a report issued Tuesday. In it, the agency summarized its best practices for thwarting attacks and said it will analyze possible real-time infiltration responses. But the agency's ability to handle hackers may only go so far.

2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.
