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.

Mitsubishi, Nissan will build mini EV together

That minicar project that erstwhile competitors Nissan and Mitsubishi launched about four years ago is about to go a little more maxi. NMKV Co., the joint venture established in June 2011 by the two Japanese automakers to make minicars, is going to get more resources specifically to ease a move into the electric-vehicle sector. Specifically, Nissan, which makes the all-electric Leaf, is going to have a bigger role in the testing, design, and development of the partnership's mini EVs. A memorandum of understand between Nissan and Mitsubishi, maker of the i-MiEV, is in the works. So far, the joint-venture has sold about 500,000 gas-powered three-cylinder compact vehicles under the two automotive brands, so it must be doing something right. The first Nissan Dayz and the Mitsubishi eK Wagon models started production in 2013. Sales of the Nissan Dayz Roox and Mitsubishi eK Space, which went the higher-roof route, began early last year. Nissan and Mitsubishi started making noise about this last summer, when word came out that the little EV may be priced at less than $15,000 in Japan, quite a bit cheaper than either the Leaf or the i-MiEV over there. As with the current models, the future minicar variants will be produced at Mitsubishi's Mizushima factory in Japan. So far, the partnership would only say that details about NMKV's next-generation mini EV will be released "at a later time," so specifics like range and other performance measures will have to wait. Until then, you can take a look at NMKV's press release below. Nissan, Mitsubishi Motors and NMKV reach agreement on planning and development of next-generation minicars Nissan Motor Co., Ltd., Mitsubishi Motors Corporation, and their joint venture NMKV Co., Ltd. today reached an agreement to continue their joint project regarding development of the next generation of current minicar models. The three companies will soon sign a memorandum of understanding. The companies aim to develop more competitive products by optimizing resource allocation and their respective roles and responsibilities. Nissan will be more deeply involved in development operations, such as design development and testing. In addition to its product planning and project development roles, NMKV will strengthen its management capabilities by adding a new department to enhance collaboration with engineering and manufacturing functions. Vehicle production is planned to continue at Mitsubishi's Mizushima Plant.

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.
