Some Jeep Cherokees and Chrysler 200s to get standard stop-start in 2015

Automakers the world over are striving to find ways to make their models more efficient, and Chrysler has a solution for some versions of the 2015 Chrysler 200 and 2015 Jeep Cherokee (2014 model shown). The Tigershark 2.4-liter four-cylinder in the 200 and the 3.2-liter Pentastar V6 in the Cherokee are getting a slight boost later this year thanks to the addition of Chrysler's Engine Stop-Start system as standard equipment. The company predicts modest gains - a three-percent improvement in fuel economy and a three percent reduction in CO2 emissions with the new tech compared to without it. While it's not much, those who sit in traffic a lot may see a difference.
Chrysler's stop/start system uses a high-speed starter motor to restart the vehicle in a claimed a third of a second. It works by detecting when the vehicle comes to a stop and turning off the engine. A more powerful battery maintains all of the model's accessories while it sits. When the driver lets off the brake, the car starts up again to drive away. There is even a button in the cabin to turn the ESS off, if desired.
The Jeep will be the first to receive ESS in the third quarter of this year to coincide with the start of production of the 2015 model-year version. The 200 will follow in the fourth quarter as a rolling change in production.

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.

Daily Driver: Long-Term 2014 Jeep Cherokee

As a fan of the boxy Jeep styling of old, I was disappointed when photos first leaked of Jeep's revived Cherokee in early 2013. Then the midsize crossover arrived in Autoblog's longterm garage in May of 2014 and my opinion did a 180. I was prompted to rethink the exterior design of the vehicle after reading our reviewer's interview with head Jeep designer Mark Allen. "The previous, blocky Cherokee was so aerodynamically inefficient, it would be wrong to do it," Allen told Autoblog's Jonathon Ramsey. That made sense. After all, Jeep is a brand associated with the outdoors, so its only natural that they seek to produce efficient, yet capable vehicles. It was then I began reconsidering the sleek lines of the new Cherokee. What once seemed bland and rounded now appeared streamlined and purpose-built. I also give Jeep credit for the slim headlamp silhouette, which look like no other SUV on the market – a far cry from the distinct circular lamps on Wranglers or squared headlights of past XJs. As I drove our long-term Jeep Cherokee Trailhawk on a few road trips, my affinity for the vehicle's comfortable interior grew as well. The seats held up to a nine-hour trek to Montreal, and the Chrysler Uconnect system made navigating the roads and the radio a breeze. Above you'll hear my early impressions of the Cherokee, and below you'll find a previous long-term update featuring Autoblog's Steven Ewing and Chris McGraw. UPDATE: The video mistakingly indicates that the Jeep Cherokee features LED headlights. The Jeep Cherokee, in fact, has daytime running lamps with LED accent lighting. Related Video:
