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.

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.

2018 Hyundai Kona vs other small crossovers: How they compare on paper

The 2018 Hyundai Kona is the hottest new thing in the hottest new segment: subcompact crossovers. Or B-segment SUVs. Or whatever you might want to call this hodge-podge collection of vehicles of vaguely similar specs. Each is pretty much just a raised hatchback in some form (or literally in the case of one entry), skewing the increasingly vague line between car and SUV. If there was ever a segment that deserved the term "crossover" for more reasons than just its car-based unibody architecture, this would be it. Now, for this specs and photos comparison, we lined up the new 2018 Kona with an appropriate variety from that hodge-podge. Most are those that people are actually cross-shopping the Kona against — the Honda HR-V, Toyota C-HR and Subaru Crosstrek — while the Kia Soul and Jeep Renegade line up well in other regards. There are certainly others we could've included, but we're frankly a little pressed for spreadsheet space, and if you really want to know how a Chevrolet Trax, Fiat 500X or Ford EcoSport would've stacked up, you can always use our Compare Cars feature. (You can also check out our Mitsubishi Eclipse Cross comparison that includes a few larger choices) Performance, fuel economy and drivetrains Immediately you can see how all over the map this segment is. True, all but the Jeep come with a standard naturally aspirated four-cylinder and fairly comparable horsepower. Torque differs, but not wildly so. Then things get nuts. Some are automatic only, the Toyota is CVT only, the Honda and Subaru come with a manual standard and offer a CVT as an option. The Renegade's base engine is manual-only ... in 2018. Of course, then things flip-flop with the Renegade's upgrade being naturally aspirated and the Hyundai and Kia offering turbocharged mills. The Korean corporate cousins also come with automated manuals, whereas the Renegade has a box with nine gears selected by a lethargic monkey. Then there's the drivetrain. The C-HR is front-drive only, which pretty much cements the Soul's place in a segment it arguably created despite not offering all-wheel drive. That's the only way to get the Crosstrek, while the Honda and Hyundai offer a typical option of a part-time system. In Jeep fashion, the Renegade's "four-wheel drive" systems differ by trim level.
