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.

Watch this 800-hp Nissan Juke-R savage the 'Ring

The concept of the 545-horsepower Nissan Juke-R that stuffs the drivetrain of a GT-R into a subcompact crossover is already insane, but Russian company Shpilli Villi Engineering has taken things even further with their own crazy riff on the idea. Its version tunes the engine up to a claimed 800 horsepower, plus a shot of nitrous for an extra 200 hp to put it (way) over the top. Naturally, a number of other upgrades have been exacted in an effort to try and keep the custom Juke's shiny side up and the driveline internals from spontaneously rearranging themselves. Those changes include a beefed-up switchable all-wheel drive or rear-wheel drive layout and revised suspension.
Last year, you may recall that we saw an earlier version of Shpilli Villi Engineering's insanity testing with a mere 700 hp in a one-mile, standing drag race against a Bugatti Veyron. In that state of tune, the Juke-R lost, but by less than a hundredth of a second. Now, owner and racer Vladimir Ulanov has brought his madness to the Nürburgring Nordschleife to see how it does around a damp lap of the famous track.
It looks like 800 hp and a moist track might be almost too much for this Juke to handle, because Ulanov gets very loose at several points during the lap. Understandably, his passenger seems suitably impressed and possibly a little freaked out at the end. See what you think of this craziness by watching the video.

Recharge Wrap-up: Rimac Concept One vs. Bugatti Veyron, Tesla Autpoilot in the snow

Watch the Rimac Concept_One and the Bugatti Veyron drive head-to-head along the Croatian coast. Rimac Automobili founder Mate Rimac invited the Earl of Pembroke to drive his 1,088-horsepower EV, while he'd drive Lord Pembroke's Bugatti for comparison. Besides the scenic coastal roads shown in this first film, the pair also drove on a racetrack and an airfield. More episodes – and a drag race – are to come. Watch the video above, and read more at Teslarati. Watch how Tesla Autosteer operates in the snow at night, with no lane markings and no lead vehicle. While Tesla doesn't recommend using Autopilot in these conditions, it seems to manage rather well. Even thought the system shows that it doesn't always recognize the curb, the car doesn't instruct the driver to take control. It's possible that data plays a key role when there aren't other guiding factors on the road, and Tesla's high resolution mapping and the car's GPS could help navigate when there is little sensor input.

Andromeda Power uses its V2V Orca Inceptive onboard charger, which is meant for CHAdeMO to CHAdeMO charging. It requires a lot of equipment, including a CHAdeMO Tesla adapter, but it's definitely one way to feed a Tesla enough juice to get to the nearest charging station. Read more at Inside EVs. Hyundai increase the range of its Tucson Fuel Cell by 30 percent. The next generation of the hydrogen powered Hyundai is expected in early 2018, and range will jump from 265 miles on a full tank to 348 miles. That surpasses the Toyota Mirai's 312-mile range, but not the 366 miles of the Honda Clarity Fuel Cell. Read more at Green Car Reports, or from the Nikkei Asian Review.
