Weekly Recap: Hackers demonstrate auto industry's vulnerability

There's always been a certain risk associated with driving, and this week cyber security came into focus as the latest danger zone when researchers demonstrated how easily they could hack into a 2014 Jeep Cherokee from across the country. The incident raised concerns over the vulnerability of today's cars, many of which double as smartphones and hot spots. During the now-infamous experiment, Chris Valasek and Charlie Miller infiltrated the Jeep's cellular connection and were able to control the infotainment system, brakes, and other functions. The hackers told the Jeep's maker, FCA US, of their findings last year, the company devised a software fix. Though Valesek and Miller hacked a Cherokee (like the one shown above), several FCA products, including recent versions of the Ram, Grand Cherokee, Dodge Durango, and Viper were also affected, illustrating potentially wide exposure that could reverberate across the sector. "For the auto industry, this is a very important event and shows that cyber-security protection is needed even sooner than previously planned," Egil Juliussen, senior analyst and research director for IHS Automotive, wrote in a research note. "Five years ago, the auto industry did not consider cyber security as a near-term problem. This view has changed." Hours after the Cherokee hacking incident was publicized on Tuesday, Sens. Ed Markey (D-Mass) and Richard Blumenthal (D-Conn) introduced legislation to direct the National Highway Traffic Safety Administration and Federal Trade Commission to establish national standards for automotive cyber security. The bill also would require vehicles to have a cyber-rating system to alert consumers how well their cars' privacy and security are defended. "Drivers shouldn't have to choose between being connected and being protected," Markey said in a statement. "We need clear rules of the road that protect cars from hackers and American families from data trackers." Though FCA and its Jeep Cherokee were in the spotlight this time, they were just the latest to showcase how automotive technology has advanced faster than safety and regulatory measures. IHS forecasts 82.5 million cars will be connected to the internet by 2022, which is more than three times today's level. "Cyber-security will become a major challenge for the auto industry and solutions are long overdue," Juliussen said.

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.

Jeep Cherokee won't get diesel until sales of oil-burning Grand Cherokee improve

Okay Jeep fans, you want more diesel options? Time to step up and prove it. The only way Jeep will offer a diesel powerplant in the Cherokee, according to brand head Mike Manley, is if sales of the Grand Cherokee EcoDiesel nearly double.
Currently, about eight percent of the Grand Cherokees sold feature the 3.0-liter, EcoDiesel V6. That's simply not enough to warrant the bringing an oil-burning Cherokee to the US market, despite the vehicle's presence in Europe, where it's sold with a 2.8-liter diesel V6.
"Cherokee is slightly different because of its weight and size. When I think about bringing Cherokee diesel here, I would like to see Grand Cherokee diesel get much higher than eight percent," Manley told Automotive News. "It would have to be in mid-double digits."
