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.

What will Detroit do with the abandoned AMC headquarters?

As with so many other industrial and residential properties in Detroit, the former headquarters for the American Motors Corporation is having a hard time finding a reputable buyer. In October the Wayne County Treasurer held a tax foreclosure auction of 25,000 properties that included the AMC building, the starting bid being $500. Nicholas Casab won the building for $500, but the county voided the sale when Casab didn't pay the $232,000 in back property taxes. Detroit authorities haven't commented on the failed sale, but the city has until January 4 to decide if it wants to keep the building. If it doesn't want to hold onto it, the 1.5-million-square-foot property on 57 acres might be ceded to the Wayne County Land Bank Corporation. No matter who holds the deed come January 5, all anyone really wants is for someone to take possession of the building who will actually turn it into something useful and viable. The property opened in 1927 as a factory for the Kelvinator Corporation. Over the following decades, Kelvinator merged with the Nash Motor Company, and that merged entity merged with Hudson Motor Car Co, becoming American Motors. Chrysler took over the building in 1987 when it bought AMC, then shuttered it in 2009. The complex has produced refrigerators, Sikorsky helicopters, Jeeps, AMCs, and was used as an engineering center for Jeeps and other Chrysler products. Having been through several hands in the past six years, it is cited as part of the cycle of abandonment plaguing Detroit.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.
