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.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Carlos Ghosn's wife appeals to President Trump to help her husband

LONDON — The wife of former Nissan chairman Carlos Ghosn urged U.S. President Donald Trump to raise her husband's case with Japan's prime minister at a summit of world leaders later this month. "I'd like President Trump to speak to Prime Minister Abe about fair conditions, fair trial conditions and to let me speak to my husband and also to respect this presumption of innocence until proven guilty," Beirut-born Carole Ghosn, who has a U.S. passport, told the BBC. Shinzo Abe is due to host other leaders of the Group of 20 economies in the Japanese city of Osaka on June 28-29. In April Carole Ghosn called on the French government to do more to help her husband. Carlos Ghosn, who holds French, Lebanese and Brazilian citizenship, is facing financial misconduct charges and has said he is the victim of a boardroom coup, accusing "backstabbing" former colleagues of conspiring to oust him as Nissan chairman. Carole Ghosn said she had not spoken to her husband since he was re-arrested on April 4 before being released on bail three weeks later. "They told him one of the bail conditions, the restrictions, is he isn't allowed to speak to me or talk to me, which I find inhumane," she said. "All of this could have been dealt with internally within the company. This didn't need to go this far and on top of it my husband is innocent and time will prove the truth."
