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.

Recharge Wrap-up: Fiat 500X emissions, Japan EV sales down

The Fiat 500X exceeds EU emissions limits, according to environmental lobby group DUH. In dyno tests, DUH found NOx emissions in the diesel-powered 500X to be 11 to 20 times the limit with a warm engine, but closer to the limit with a cold engine. Testing of vehicles from Fiat and other automakers "point towards defeat devices," says DUH campaigner Axel Friedrich. Fiat Chrysler Automobiles (FCA) offered no comment in response to the accusations. Read more from Reuters. A UK study finds that about 20 percent of the benefits from fuel efficient vehicles are negated by a tendency for people to drive them more. The study, which covers the years 1970 to 2011, finds a significant "rebound effect," when consumers use more of a cheaper energy source. It suggests these drivers drive more not because of the fuel efficiency, but because of the lower operating costs. "Until now, we didn't know the size of this effect for British motoring," says Dr. Lee Stapleton, Research Fellow for the University of Sussex Centre on Innovation and Energy Demand. "We found evidence of a significant, long-term rebound and expect our results to be of interest for public policy." Read more at Green Car Congress. Japanese EV sales have declined for the first time ever. Sales of electric vehicles slid 22 percent in 2015, leaving them at the same levels as 2012. Low gasoline prices are to blame, as well as the late arrival of the updated Nissan Leaf, which caused potential customers to hold off on their purchase. This allowed the Mitsubishi Outlander PHEV to take the lead as Japan's best selling EV. The Toyota Prius Plug-In came in third place in EV sales, with the BMW i3 close on its heels.

Is 120 miles just about perfect for EV range?

When it comes to battery-electric vehicles, our friend Brad Berman over at Plug In Cars says 40 miles makes all the difference in the world. That's the approximate difference in single-charge range between the battery-electric version of the Toyota RAV4 and the Nissan Leaf. It's also the difference between the appearance or disappearance of range anxiety. The 50-percent battery increase has zapped any lingering range anxiety, Berman writes. The RAV4 EV possesses a 40-kilowatt-hour pack, compared to the 24-kWh pack in the Leaf. After factoring in differences in size, weight and other issues, that means the compact SUV gets about 120 miles on a single charge in realistic driving conditions, compared to about 80 miles in the Leaf. "The 50 percent increase in battery size from Leaf to RAV has zapped any lingering range anxiety," Berman writes. His observations further feed the notion that drivers need substantial backup juice in order to feel comfortable driving EVs. Late last year, the Union of Concerned Scientists (UCS), along with the Consumers Union estimated that about 42 percent of US households could drive plug-in vehicles with "little or no change" in their driving habits, and that almost 70 percent of US commuters drive fewer than 60 miles per weekday. That would imply that a substantial swath of the country should be comfortable using a car like the Leaf as their daily driver - with first-quarter Leaf sales jumping 46 percent from a year before, more Americans certainly are. Still, the implication here is that EV sales will continue to be on the margins until an automaker steps up battery capabilities to 120 or so miles while keeping the price in the $30,000 range. Think that's a reasonable goal to shoot for?
