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 and NASA team up on autonomous zero-emissions test fleet

Nissan and NASA have announced a collaboration on autonomous vehicles that, if we're honest, makes more sense to us than Infiniti partnering with Red Bull. The two are commencing a five-year R&D program to explore autonomous drive systems, human-machine interfaces, network-enabled applications, and software analysis and verification. What's more: the test fleet will be zero emissions and rolling around NASA's Ames Research Center by the end of this year. We will assume that means autonomous Leafs, but Nissan could be working on a new vehicle for the purpose. Nissan CEO Carlos Ghosn said the company will begin offering autonomous features "beginning in 2016," and wants to have commercially available self-piloting vehicles that can "navigate in nearly all situations," including urban environments, by 2020. Who better to assist than the people who put a self-driving rover on a planet that never gets closer than 34 million miles away? What does NASA get out of it? Access to Nissan's materials and component developments, prototyping systems, and robotic software test beds. Sounds like everybody wins. The press release below has more information. Nissan and NASA partner to jointly develop and deploy autonomous drive vehicles by end of year SUNNYVALE, Calif. Jan. 8, 2015 - Nissan Motor Co., through its North American-based organization, and NASA today announced the formation of a five-year research and development partnership to advance autonomous vehicle systems and prepare for commercial application of the technology. Researchers from Nissan's U.S. Silicon Valley Research Center and NASA's Ames Research Center at Moffett Field, Calif., will focus on autonomous drive systems, human-machine interface solutions, network-enabled applications, and software analysis and verification, all involving sophisticated hardware and software used in road and space applications. Researchers from the two organizations will test a fleet of zero-emission autonomous vehicles at Ames to demonstrate proof-of-concept remote operation of autonomous vehicles for the transport of materials, goods, payloads and people. For NASA, these tests parallel the way it operates planetary rovers from a mission control center. The first vehicle of that fleet should be testing at the facility by the end of 2015. "The work of NASA and Nissan – with one directed to space and the other directed to earth, is connected by similar challenges," said Carlos Ghosn, president and CEO of Nissan Motor Co.

Nissan Leaf sells 3,186 in best month ever as Chevy moves 2,511 Volts

The end of summer seems to inspire people to go out and buy a lot of plug-in vehicles. Last year, for example, the Chevy Volt had its best month ever in August, with 3,351 sales. This year, the Nissan Leaf is going up to the winner's podium, setting its own best-ever record with 3,186 units sold. This beats the Leaf's previous record by 69 vehicles. This beats the Leaf's previous record of 3,117 set in May 2014 by 69 vehicles and is up 31.7 percent from August 2013. Nissan is once again quick to remind us that the popular EV's record sales streak has now been extended to 18 months in a row. This record is simply noting that the current month, in this case August, had the highest sales that that month has ever seen in the US. Over all, US Leaf sales are up 34.1 percent so far this year. In a prepared statement, Nissan's director of Leaf sales and infrastructure, Brendan Jones, said that the Leaf is selling well on both coasts, including cities like Raleigh, Boston and Washington, DC. "It's what we call the 'cul-de-sac phenomenon,' where once someone in a community buys a Leaf, then friends, family, co-workers and neighbors see the benefits of this fun-to-drive electric vehicle firsthand and are sold on the idea of going electric," he said. The Volt also had a good month - its best of 2014 by almost 500 sales – but the 2,511 Volt sales still represent a drop of 25.1 percent from the excellent sales the Volt had this time last year. In fact, August 2014 represents the Volt's best sales month since, well, August 2013. Apparently, there's just something about the end of summer. As always, we are working on our in-depth round-up of green car sales across the country and will have that up soon.
