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.

Nissan alters all CVTs to act less like a stretched rubberband

Among automotive enthusiasts, no one seems to hold a neutral opinion when it comes to continuously variable transmissions. CVTs are either praised for their ability to boost fuel economy or chided for their occasionally poor driving dynamics. Nissan is among the masters of these un-shifting gearboxes in the US, and it uses them in many vehicles in its lineup. However, for the 2015 model year, several models are getting a software update to make their CVTs a bit more like a conventional automatic.
To give drivers the option of feeling gearshifts while on the road, Nissan is adding its D-Step Shift Logic feature to the CVTs in multiple vehicles. Steve Powers, Nissan's senior manager of powertrain performance, told Autoblog the system forces the transmission to "hold a ratio and then shift" to simulate the way that a traditional automatic would. It's simply a change in software, but the company "can't do it to older CVTs," he said, because it would require changes to transmission logic, as well. According to Automotive News, the upgrade is coming to the 2015 Versa, Versa Note (pictured above), Sentra, V6-equipped Altima, Pathfinder and Quest. "We're rolling it out to all programs," said Powers.
Interestingly, buyer perception appears to be pushing the upgrade. John Curl, a Nissan North America regional product manager, told Automotive News that the decision to add the tech partially comes because some owners are bothered that the CVTs aren't changing gears. According to Powers, D-Step "avoids the rubber band feel," that many drivers didn't like. The different sensation of these transmissions seems like something consumers would notice during the test drive, or that the salesperson would inform them about. The same issue cropped up last year when the company was facing customer satisfaction problems among new buyers customers' unfamiliarity with the gearboxes.

Bug-eyed next-gen Nissan Titan spied testing

It's no secret that the fullsize pickup truck market is dominated by offerings from Detroit's Big Three automakers, the Nissan Titan and Toyota Tundra not able to outdo the Ford F-150, Ram 1500 or Chevy Silverado/GMC Sierra twins. A great deal of that has to do with the fact that, while the American trucks have all undergone evolutionary updates that include a range of body styles, fuel-efficient engines and excellent technology, the Japanese offerings are, well, really old. Toyota is offering an updated Tundra for the 2014 model year, and while we haven't driven it yet, we're already betting that it's still behind the pack in terms of competitiveness - the 2013 model placed fifth out of sixth in a recent PickupTrucks.com comparison test.
At the bottom of the pack lies the Nissan Titan, a truck that hasn't received any sort of substantial update since its introduction nearly ten years ago. But that's going to change - a new truck is slated to debut for the 2015 model year, and these spy shots of a Titan mule clearly show that things are moving forward.
While this tester relies heavily on the current truck's bodywork for testing purposes, the new Titan will have a revised design, some of which is evidenced by the bug-eyed front fascia of this mule. No, the production model isn't going to look all weird (we hope), but the higher, more outboard headlight placement suggests that the new truck will be a bit wider than the current model.
