Nissan shows self-cleaning car coated in nano paint

Washing the car is an activity like mowing the lawn that some people love and others find to be an absolute chore. For the latter group, Nissan may have an answer. Nissan is testing a nano-paint coating that could make the car wash a very infrequent place to visit.
Shown on a European Note hatchback, the key is a special layer of super-hydrophobic and oleophobic material called Ultra-Ever Dry that is sprayed over the paint. It creates a protective layer between the body and environment, and it means that when dirt or water come into contact with the car, the gunk just sheets away.
Nissan admits that the coating is still early in testing. The key will be if the stuff can actually last for the long term, and the company will be analyzing it over the coming months to see how it will react in different conditions. At the moment, the automaker has no plans to offer Ultra-Ever Dry as a standard feature, but it may make it available as an aftermarket addition in the future. Scroll down to watch the video of Nissan testing the stuff in some very dirty conditions.

Nissan CEO Makoto Uchida rules out closer capital ties with Renault

YOKOHAMA — Nissan is committed to its automaking alliance with Renault but will not look to deepen its capital ties with the French automaker any time soon, its new CEO said on Monday. On his first day in the new position, chief executive Makoto Uchida also pledged to repair profitability at Japan's No. 2 automaker and said setting realistic targets would be key toward that goal, as it tries to make a clean break from the leadership of former chairman Carlos Ghosn. "Closer capital ties with Renault are not a focus in the short term," he told reporters. Uchida became CEO of Nissan on Dec. 1, as the car maker tries to recover from a profit slump and draw a line under a year of turmoil after the Ghosn scandal. The ousted chairman is fighting financial misconduct charges in Japan. One of the new CEO's big tasks is to salvage ties with Renault, which have deteriorated since Ghosn's ouster as chairman of both companies. Renault holds a 43.4% stake in Nissan after it saved the Japanese automaker from financial ruin two decades ago, and has pushed for the two companies to merge. In rejecting a notion of a merger with Renault, Uchida, 53, echoes his predecessor Hiroto Saikawa, who stepped down in September. He added that the alliance must re-think how it can serve all of its three members, which also includes Mitsubishi Motors. "The alliance has to benefit each of its partners in terms of revenue and profit," he said. "We need to re-evaluate what has worked and what hasn't worked in the alliance in the past few years." The CEO called for Nissan to set "challenging but achievable" targets, adding that this and the launch of more new car models and vehicle technologies would be key to its financial recovery. Nissan is bracing for its lowest annual profit in 11 years and has slashed its dividend by 65%. Its struggles come at a time when car companies desperately need scale to keep up with sweeping technological changes like electric vehicles and ride-hailing. "Somewhere along the way we created a culture of setting targets which could not be achieved," Uchida said, adding that this had resulted in a focus on short-term results. "Years of this had led Nissan to its current "difficult situation," he said, using heavy vehicle discounting in the U.S. market as an example of how aggressive sales targets to grow market share had deteriorated the company's brand.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
