Supplier says Jeep Cherokee hack only affects FCA cars

Harman doesn't think that drivers need to worry about any further hacks of its products. The company supplies FCA's Uconnect infotainment system where a software vulnerability is responsible for a 1.4-million vehicle recall. "This experimental hack is unique to Chrysler," Harman CEO Dinesh Paliwal said to Automotive News. "This does not exist, to our assessment, in any other vehicle." The reason that the company wouldn't be involved is that automakers aren't simply plugging in the existing infotainment systems into new vehicles. According to Paliwal, Harman supplies the unit, but FCA and other automakers are able to make additional modifications for their vehicles. The National Highway Traffic Safety Administration has also recently taken up the question of broader software vulnerabilities in Harman's products. On July 29, the agency began investigating the company to check for similarities between Uconnect and the infotainment systems supplied to other automakers. The Jeep hack became national news when two researchers were remotely able to take control of a Cherokee. The vulnerability in the cellular connection even gave control over the brakes. "Once people get in the car and get into the CAN bus, then you can start to mimic and mess up many, many things in the car," Paliwal said to Automotive News. Politicians immediately responded with legislation to create federal standards in hopes of protecting drivers better. NHTSA also opened an investigation to make sure the automaker's software update actually solved the problem. Related Video:

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.

Jeep shows off Moab Easter Safari concepts crawling the red rocks

While most brands are busy showing off in New York, Jeep headed out to Moab for the Easter Jeep Safari with the company's fleet of 2013 concepts. This year saw the Grand Cherokee Trailhawk II, Wrangler Mopar Recon, Wrangler Stitch, Wrangler Sand Trooper II, Wrangler Flattop and Wrangler Slim Concepts tackle the rocks and sand, and Jeep was kind enough to bring along a camera crew to film the machines rolling over a few obstacles. The result is the video below, though don't expect to see too much hardcore off road action.
Instead, the quick clip features more than a few interviews with Jeep executives, including Jeep Head of Product Design Mark Allen, explaining what makes the Easter Jeep Safari so important. You can check out the quick clip below for yourself, and be sure to thumb through our galleries of the concepts as well.
