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.

Cadillac tops Tesla in Consumer Reports semi-automated driving test

General Motors' Cadillac outscored Tesla in a new ranking of partially automated driving systems tested by Consumer Reports and released on Thursday. The highly influential nonprofit organization, which tests and rates a variety of consumer products from appliances to vehicles, said it compared Cadillac's Super Cruise and Tesla's Autopilot with similar systems from Nissan and Volvo. Nissan's ProPilot Assist was ranked third and Volvo's Pilot Assist fourth. Consumer Reports said it has been testing partially automated driving systems for several years but elected to conduct a formal study intended for publication, because "we are at a tipping point where they are now going mainstream," according to Jake Fisher, director of auto testing. The organization said its tests, conducted on a private track and on public roads in Connecticut, were designed to measure the systems' ability to automatically control steering and speed in certain situations, while helping drivers pay attention and regain manual control of the vehicle when required. CR noted that any of these systems can increase driving risk if used in inappropriate situations, or if drivers become inattentive or over-reliant on them. While they can help relieve driver stress and fatigue, Consumer Reports said, the partially automated systems are "not intended to be self-driving features." The systems typically use cameras, radar and other sensors, as well as mapping data, to monitor location and traffic conditions and help keep a vehicle centered in the lane at a safe distance behind other cars. Each system has limitations. Cadillac's Super Cruise, for instance, only functions on divided highways that have been mapped by GM. In contrast, Tesla's Autopilot can be used even on small, curvy roads with poor lane markings, but "operates erratically in those situations," Consumer Reports said.The organization tested Super Cruise on the Cadillac CT6; Autopilot on the Tesla Model 3, Model X and Model S; ProPilot Assist on the Nissan Leaf and Infiniti QX50; and Pilot Assist on the Volvo XC40 and XC60. Consumer Reports said Cadillac's Super Cruise did "the best job of balancing high-tech capabilities with ensuring the car is operated safely and the driver is paying attention." Tesla's Autopilot was cited for its capability and ease of use, while Nissan's ProPilot Assist did a better job than Autopilot or Volvo's Pilot Assist in keeping drivers engaged.

A realistic approach to fixing Mitsubishi

There are going to be a lot of words written about what Nissan needs to do with Mitsubishi in the coming months and years in the interest of turning the brand around. After Nissan's purchase of a controlling stake in the diamond star brand, there's been more interest in Mitsubishi thanks to the potential of platform sharing and plenty of cash from Nissan-Renault to get the juices flowing again. But, while some have been doing their best to advocate for the return of the 3000GT, Evolution, and even the Starion - Many of these posts forget the reality of the market we live in today. As much as we like to look back fondly at the sports coupes of the '90s, a byproduct of the insane cash flows all the Japanese manufacturers had at the time, the reality of today puts a much greater emphasis on what is most-boring; Crossover SUVs, alongside mid-size and compact sedans. We do need to ask a fundamental question, how much Mitsubishi is enough to be able to continue to call the cars Mitsubishis? Aside from slight product revisions and reconfigurations, Mitsubishi (at least in North America) has been largely dependent on the same GS platform and 4B1 engines that date back to their long-time partnership with Chrysler (and Hyundai) in the mid '00s. Admittedly, the chassis and engines have served the company well, underpinning a wide variety of vehicles sold around the world, and seeing quite a few revisions to at least attempt to keep products competitive. But, the GS chassis is old, heavy, and severely out of date - and when matched to the underpowered 4B1 series engines - make for largely uncompetitive offerings in the market. While something like the Outlander Sport is indeed interesting compared to a Honda CR-V, it is by no means the smart choice in the segment. So, going forward, unless Mitsubishi has had a skunkworks of sorts developing their chassis and engine replacements over the past few years, what exactly are they planning to do for their bread-and-butter models? I think the straightforward answer is without a doubt the Nissan North America parts bin. With so many of their models selling well, and for the most part, are reasonably well-reviewed, it would be quite simple to adapt the chassis and powertrain to Mitsubishi's liking to create a high-volume alternative to what is currently available now.
