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.

Renault, Nissan limit French government interference

Renault and Nissan are taking action to limit the influence that one can exercise over the other's operations. The measures, announced by both automakers after meetings of their respective boards in Paris and Tokyo, aim to keep each other at arm's length. But more than that, they seek to cap the degree of influence which the French government can bring to bear on either automaker. The steps are being taken in response to investment moves by the French state. While the government's investment arm – known as the Agence des Participations de l'Etat (or state participation agency) – previously controlled 15 percent of Renault's shares, it increased its holdings this April to 19.73 percent. The action sparked concerns at Renault that the French government would attempt to dictate operating procedures to both automakers, potentially to favor production in France over other locations. Given that Renault holds a 43-percent stake in Nissan, the Japanese automaker grew concerned over potential French state interference as well. To assuage those concerns, Renault, Nissan, and the French government came to an agreement with three vital clauses. Most importantly, despite its nearly 20-percent holdings, the French government will be granted only 17.9 percent of voting rights in Renault (to be extended up to 20 percent under certain exceptional circumstances). Renault (and by extension the French government) will also be prevented from interfering in Nissan's governance. With those measures in place, Nissan will not seek more voting rights based on the 15-percent stake which it, in turn, holds in Renault. Having successfully concluded the deal and hedged against the threat of government interference, the Renault board reasserted its confidence in Carlos Ghosn. Through the unique terms of their alliance, Ghosn serves as chairman and CEO of both Renault and Nissan. The two cooperate closely and share resources extending far beyond their chief executive, but remain distinct companies rather than merge, as Fiat and Chrysler have. Renault Board approves alliance stability covenant between Renault and Nissan As early as 16th April 2015, the Renault Board of Directors unanimously reiterated that the sustainability, success and resilience of the Alliance since its very inception in 1999 were based on a balance of shares held by Renault and Nissan.

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.
