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.

Nissan Leaf battery cells put through torture test, live to charge again

One minor chink in the armor of the Tesla Model S is that a small number have caught fire, once their battery packs were penetrated. Nissan Leaf drivers, however, might just be able to weather such an event without an ensuing CarBQ. Our evidence for such a claim? A video that has surfaced of cells from a Leaf pack undergoing a battery of torture tests (pun somewhat-ashamedly intended). Shared by folks at the Hybrid Auto Center in Las Vegas – who offer for sale, among other things, used Leaf lithium battery modules – the footage shows salvaged cells being brutally assaulted with a screwdriver, and later, a propane torch. Granted, these tests are not the same thing as flinging a piece of metal into a working pack at 70 miles per hour, but they do claim to show that a puncture does not always equal a fire. Oh, and don't try this at home. When pierced through by the flat head tool, there is no explosion or eruption of flame. Instead, a rather modest wisp of smoke shyly emerges as the electrolyte next to the shorted area of the fully-charged foil pouch reacts with the influx of oxygen. Again and again, the blade descends, until the cell is riddled with holes. No fire. Amazingly, when connected with a voltmeter afterward there are still plenty of signs of life, and when it is charged and discharged (off-camera), it reportedly suffers only a slight loss of charge capacity. The video goes on to show another cell attacked with open flame with similar results. While the demonstration is, perhaps, somewhat crude, the message it sends is loud and clear: lithium batteries can be safe and rather robust, despite some freak accidents.

Recharge Wrap-up: No Tesla Gigafactory deal with California, BMW i3 recalled

Before the Nevada announcement was hinted at, a deal to incentivize a Tesla Gigafactory in California fell through. Tesla was looking for around $500 million in incentives, which the California Governor's Office of Business and Economic Development was willing to offer in tax breaks along with making the permit and environmental processes easier. According to Senator Ted Gaines, there still remained "a gap between what Tesla wanted and what California was willing to offer," the contents of which were undisclosed. California could still be chosen for another of Tesla's battery plants, should those ever materialize. Read more at The Desert Sun. The California Air Resources Board (CARB) will consider allowing a bit of compliance flexibility to its Zero Emission Vehicle (ZEV) regulations for some automakers. CARB will hold a hearing to discuss giving intermediate volume manufacturers (IVMs) - carmakers that do between 4,501 and 60,000 new vehicle sales in the state - some leniency catching up to the larger manufacturers when it comes to clean vehicle production. The ZEV regulation changes take into account the amount of revenue IVMs have available for developing the cars, particularly plug-in hybrids. Read more at Green Car Congress or see the notice from CARB here. Certain units of the BMW i3 are subject to an airbag recall. For cars built March 31, 2014, the passenger airbag inflator may have been assembled incorrectly, which could keep it from deploying when needed. Owners will be notified by BMW, and the problem will be fixed for free. The recall also affects certain 2014 Mini Cooper models. Learn more at the NHTSA website. The Renault-Nissan Alliance is providing 200 electric vehicles to telecommunications company Orange in France. The cars, which will include the Nissan Leaf, Nissan e-NV200, Renault ZOE and Renault Kangoo ZE, will be used mostly for carsharing. Through the program, Orange employees can book a car for work or personal travel using a smartphone. The Alliance will also help Orange install charging stations for the new cars. The addition of the EVs to the fleet will help Orange achieve its goal of reducing its carbon footprint by 20 percent by 2020. Read more in the press release, below. Jianghuai Automobile Company (JAC) is delivering its first 100 EVs to the US. The shipment is part of a larger order of 2,000 cars to be sold by GreenTech Automotive in the US market.
