Before next-gen arrives, Nissan Leaf may get 120-mile battery

As Nissan prepares to unveil its next-generation Leaf electric vehicle, the Japanese automaker may come out with an "interim" version of sorts that could spur lagging sales of the model in the US. So says Automotive News, which reports from a person familiar with the process who wasn't identified that Nissan soon may start selling a Leaf with a 30-kilowatt-hour battery, up from the current 24 kWh version. It could arrive as soon as next month. Indeed, Nissan's temporary solution may be to provide range-hungry drivers with a single-charge range of 100 to 120 miles. Sure, that doesn't quite match up with the distance a gas-powered vehicle can go on a full tank, but it would be an notable upgrade from the current single-charge range of 84 miles for the Leaf. Word first got out about the Leaf possibly adding a 30-kWh battery in late May. Nissan's contending with falling Leaf sales in the US that may be caused by both the expiration of some plug-in vehicle credits as well as the prospect of a glut of used Leafs back on the market as three-year leases run out. Through the first half of the year, Nissan sold 9,816 Leaf vehicles in the US, a 23-percent drop from a year ago. Nissan CEO Carlos Ghosn said in a June 23 shareholders meeting that the company can improve battery technology enough to put an electric vehicle's single-charge range on par with the distance a conventional car can go on a full tank of gas.

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.

'Zero' chance of Renault taking over Nissan, Mitsubishi, says Ghosn

TOKYO — Renault SA absorbing Nissan Motor Co. and Mitsubishi Motors Corp is not an option as the carmakers look to strengthen their partnership while retaining their autonomy, alliance chairman Carlos Ghosn said on Friday. "Anybody who will ask Nissan and Mitsubishi to become wholly owned subsidiaries of Renault has zero chance of getting a result," Ghosn told shareholders of Mitsubishi Motors at a meeting. He also serves as chief executive of France's Renault. The alliance was the world's top-selling passenger vehicle maker in 2017, but as the global auto industry consolidates, it is looking to strengthen its position before the 64-year-old Ghosn, its main architect, retires in the coming years after overseeing the partnership for nearly 20 years. We reported in March that the carmakers were discussing a deeper tie-up, which could see the French government, a major shareholder in Renault, give up influence at Renault and the French carmaker relinquish control over Nissan. The three automakers have a unique partnership designed to leverage their combined scale to save on costs including R&D, parts procurement and production to better compete with rivals Volkswagen AG and Toyota Motor Corp. They are also interlinked by their shareholding structure. Renault holds 43.4 percent of shares in Nissan, while Nissan owns 15 percent of Renault, with no voting rights in a partnership that began in 1999. Mitsubishi Motors joined the alliance in 2016 after Nissan took a 34 percent controlling stake in the smaller automaker. Nissan CEO Hiroto Saikawa has said the alliance is not discussing a "full merger." Ghosn said that while the focus of the alliance was to sell more cars and increase profitability by reducing unnecessary duplication of processes, he wanted each of the three automakers to maintain their independence, which differentiated the group from Toyota and Volkswagen. "We need to work together ... to find a system by which what we have today, which is working very well, can continue in the future no matter who is leading the alliance," he said. "We need to prove that this is sustainable five years down the road, 10 years down the road, 15 years down the road." In a Figaro interview published last week, Ghosn was upbeat about the prospect of securing a new deal for the alliance despite its extreme political sensitivity in France and Japan, saying a plan would need to be announced "well before" the end of his four-year term at the helm of Renault in 2022.
