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 Pathfinder, Infiniti JX in transmission safety probe

Nissan may be forced to recall 110,000 Pathfinder and Infiniti JX35 crossovers, due to a number of customer complaints. Consumers report suddenly losing power, with repair facilities blaming the issue on faulty transmission cooler line connections. Both the Pathfinder and JX35 use a continuously variable transmission. As of right now, the only vehicles being investigated are from model year 2013.
Nissan has been cooperating with the National Highway Traffic Safety Administration, according to a report from Reuters, and it has developed a fix for the affected vehicles. It's not clear whether this will develop into a full-blown recall, as there have been no known cases of injuries or crashes. But with a potential 110,000 vehicles prone to sudden power loss, a recall seems to be a likely outcome.

Williams developing hybrid system for next Nissan GT-R?

Back in June, Nissan announced a new partnership with Williams that would see the Formula One team's applied sciences division help develop a new line of Nismo performance models. It's not the only agreement Renault-Nissan has signed with an F1 team: Infiniti is the title sponsor for Red Bull and Renault powers four teams on the grid. It's also just the latest client Williams has signed a deal with to apply the lessons it has gleaned on the F1 circuit to other racing and sportscars. But now we've got some more info on how Williams and Nismo intend to collaborate on the next-generation GT-R.
According to Australia's Carsales, Williams Advanced Engineering is developing the hybrid powertrain that will boost the next iteration of the supercar-slayer known as Godzilla. Which may seem strange considering that the Renault-Nissan Alliance has plenty of experience with electric propulsion on its own, but then Williams has proven itself something of a leader in the field of performance hybrid powertrains: it supplies them to Porsche and Audi for their Le Mans racecars, and to Jaguar for the C-X75 concept.
Whether Williams and Nismo will settle on a flywheel-based energy recovery system or a more conventional battery-powered system remains to be seen, but brakeforce regeneration likely won't be the only element that Williams will develop for the next GT-R. Expect its expertise in aerodynamics and composites to come to bear as well, which can only mean good things for the replacement for a sportscar that's already one of the most capable on the road.
