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.

Editors' Picks January 2022 | Ford Maverick, Jeep Grand Cherokee and more

This month, we awarded Editors' Pick awards to a number of totally redesigned, new models. Most notable of the bunch is the 2022 Ford Maverick. Ford took a chance on a new segment, and its execution is as close to perfect as we could hope for. The Hyundai Santa Cruz is a worthy competitor, though, and was also named an Editors' Pick. Also in this list, we have the redesigned Jeep Grand Cherokee. It's an excellent SUV, and it's only going to get better when the plug-in hybrid 4xe model hits the roads. In case you missed our previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in January that earned an EditorsÂ’ Pick. 2022 Jeep Grand Cherokee Quick take: Jeep's midsize SUV hits it out of the park with the latest generation. We could stand to see some powertrain innovation, but the Grand Cherokee's premium proposition is sound. Score: 8.0 What it competes with: Honda Passport, Hyundai Santa Fe, Ford Edge, Chevrolet Blazer, Nissan Murano Pros: Highly capable, luxurious interior, choices aplenty Cons: Pricey, fuel economy From the editors Associate Editor, Byron Hurd — "Jeep did almost everything right with the redesigned Grand Cherokee. Its powertrain offerings are fairly unremarkable, but the new two-row 4xe will go a long way toward addressing that. It's an otherwise fantastic, modern, luxurious Jeep SUV." In-depth analysis: 2022 Jeep Grand Cherokee First Drive Review | 1 fewer row, 1 more touchscreen   2022 Ford Maverick Quick take: The Ford Maverick offers tremendous value, efficiency, incredibly well-thought-out packaging, plenty of storage, a fairly engaging drive and ease of use, all with the utility of a pickup bed. We like the hybrid, but the EcoBoost engine and FX4 package offer more capability. Score: 8 What it competes with: Hyundai Santa Cruz Pros: Very affordable, Hybrid fuel economy, compact size Cons: Tight backseat, FWD only Hybrid, no cruise control in base trim From the editors: Green, Senior Editor John Beltz Snyder — "The Maverick is simply a dynamite package. It's smart, useful, drivable, efficient, providing affordable utility in the underserved compact pickup segment.

Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.
