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.

Nissan Juke to get higher-performance Nismo RC model

It's hard to find more giggles for your crossover dollar than the Juke - regardless of how you feel about the way it looks, the singularly styled nichemobile from Nissan is very entertaining to drive. Yet we've always felt that the platform had more in it, and evidently its Japanese parent agrees, having recently bracketed the googly-eyed turbocharged CUV with a new Nismo model and the barking mad built-to-order Juke R. At present, neither the Juke Nismo or the GT-R-powered Juke R are sold in North America, but the former has already been confirmed for sale here.
Even when it does reach our shores, there will still be a heck of a lot of whitespace between the mild performance upgrades of the standard Nismo and the half-mill R model, and to hear the UK's Car tell it, Nissan has plans to plug that gap, too. According to its report, the automaker will shortly offer a Juke Nismo RC that will have roughly 20 horsepower more than the basic Nismo (which itself has 197 hp, nine more than the base Juke). The RC will apparently feature a lower, stiffer suspension, upgraded brakes and a unique exhaust and intake for a snarlier soundtrack. Both front-and all-wheel drive models are planned, as are manual and CVT transmission choices.
No word yet on the RC's pricing or even North American availability, but the regular-strength Juke Nismo is expected to arrive shortly, and Nissan is also said to have big plans for its performance nameplate, so we wouldn't rule it out.
