The problem with how automakers confront hacking threats

More than anyone, Chris Valasek and Charlie Miller are responsible for alerting Americans to the hacking perils awaiting them in their modern-day cars. In 2013, the pair of cyber-security researchers followed in the footsteps of academics at the University of Cal-San Diego and University of Washington, demonstrating it was possible to hack and control cars. Last summer, their research established which vehicles contained inherent security weaknesses. In recent weeks, their latest findings have underscored the far-reaching danger of automotive security breaches. From the comfort of his Pittsburgh home, Valasek exploited a flaw in the cellular connection of a Jeep Cherokee and commandeered control as Miller drove along a St. Louis highway. Remote access. No prior tampering with the vehicle. An industry's nightmare. As a result of their work, FCA US recalled 1.4 million cars, improving safety for millions of motorists. For now, Valasek and Miller are at the forefront of their profession. In a few months, they could be out of jobs. Rather than embrace the skills of software and security experts in confronting the unforeseen downside of connectivity in cars, automakers have been doing their best to stifle independent cyber-security research. Lost in the analysis of the Jeep Cherokee vulnerabilities is the possibility this could be the last study of its kind. In September or October, the U.S. Copyright Office will issue a key ruling that could prevent third-party researchers like Valasek and Miller from accessing the components they need to conduct experiments on vehicles. Researchers have asked for an exemption in the Digital Millennial Copyright Act that would preserve their right to analyze cars, but automakers have opposed that exemption, claiming the software that runs almost every conceivable vehicle function is proprietary. Further, their attorneys have argued the complexity of the software has evolved to a point where safety and security risks arise when third parties start monkeying with the code. Their message on cyber security is, as it has been for years, that they know their products better than anyone else and that it's dangerous for others to meddle with them. But in precise terms, the Jeep Cherokee problems show this is not the case. Valasek and Miller discovered the problem, a security hole in the Sprint cellular connection to the UConnect infotainment system, not industry insiders.

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.

Chrysler extends fuel tank warranties on LX cars, NHTSA ends probe

The National Highway Traffic Safety Administration has ended its investigation of 153,817, 5.7-liter and 6.1-liter Hemi V8-powered 2006 Chrysler 300, Dodge Charger and Dodge Magnum models after reports of stalling. Chrysler has responded by granting a lifetime warranty on the fuel tanks for these vehicles.
NHTSA received 299 reports of engines stalling while the models were stopped or driving at low speeds, and began an investigation. The government agency found that the control valve shutoff float in the V8s' 19-gallon fuel tank could malfunction if the fuel had too high of an ethanol content. In many cases, the valve would break in the open position, allowing the tank to be overfilled, which would then cause the cars to stall. However, there were no accidents reported, and the vehicles could be restarted immediately.
There will not be a recall on these vehicles because, "the condition represents a low risk to motor vehicle safety and is adequately addressed by Chrysler's extended warranty," NHTSA said to The Detroit News.
