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.

Ram and Jeep diesel emissions allegations spur class action lawsuits

This shouldn't come as a surprise. Last week, the EPA issued a notice of violation to FCA after it determined that Jeep and Ram installed eight undisclosed auxiliary emissions control devices on diesel vehicles. Since then US law firm Heninger Garrison Davis, LLC and Canadian firm Sotos LLP have launched class action suits on behalf of owners. These latest lawsuits are unrelated to a previous class action suit brought against FCA and Cummins over NOx emissions in 2007 to 2012 Ram models. The violation notice – and the subsequent lawsuits – covers 2014 to 2016 Jeep Grand Cherokee and Ram 1500 models equipped with the 3.0-liter turbodiesel V6, a total of about 104,000 vehicles in the US. The EPA says that while the emissions control devices aren't necessarily illegal, installing them without disclosing them to the EPA is, as they produce more emissions in real world use than in testing. Skirting certification in this way might be a violation of the Clean Air Act. FCA could see fines of up to $45,000 per vehicle, depending on the outcome of the EPA investigation. FCA denies that these are cheat devices, and has proposed software updates to bring the vehicles into compliance. As for the lawsuits, Heninger Garrison Davis says that "Fiat Chrysler marketed those vehicles as environmentally friendly with enhanced fuel efficiency, better performance, and lower emissions. Although the diesel vehicles were successfully marketed as 'clean,' their environmentally-friendly representations were deceptive to consumers." The suit seeks an undisclosed amount of compensation for owners of these vehicles. In Canada, Sotos LLP is seeking $250 million in damages on behalf of owners. This suit, filed in the Ontario Superior Court of Justice, also claims deception on the part of FCA, "resulting in losses and damage" to owners. These are similar claims to group actions against Volkswagen with regard to its diesel emissions cheating scandal. While VW is fixing or buying back many of the affected vehicles, the company is defending itself against some suits on behalf of owners, saying it expects " no decline in the residual values of the affected vehicles as a result of this issue." Don't be surprised if FCA mounts a similar defense.

Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).
