Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

2015 Ram 1500 Rebel is rugged, oddly styled

Feeling rebellious? Ram has you covered for 2015 with its new 1500 Rebel model, which, though nowhere near as focused as the Ford F-150 Raptor with which you may think it competes, is skewed toward the always-nebulous "outdoor lifestyle" set that marketing teams the world over seem to covet so much. For such hiking/camping or otherwise outdoorsy types, the Ram Rebel offers an extra inch of suspension travel over regular-grade 1500 models, along with 33-inch tires, a new bumper that affords a better approach angle, tow hooks and a center skid plate. Those are the kind of upgrades many buyers consider mandatory for basic off-road capability, and it's nice that Ram has baked them into a single model. We're less enthused by the in-your-face styling of the rebel, particularly up front, where the traditional crosshair grille has been replaced by a protruding proboscis that's nothing if not unique. There's also massive RAM lettering on the tailgate, just in case you weren't sure who made the Rebel... The show truck's red exterior is mimicked inside, and the leather seats are embossed in a tire-tread pattern. Subtle, it is not. Buyers will have the choice of a 3.6-liter V6 or 5.7-liter Hemi V8 engine, mated to an automatic transmission and the choice of two- or four-wheel drive, though we don't understand why anyone would choose a Rebel without 4x4. In any case, check out the live pics above and the press release and videos below for more details.

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.
