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.

Nissan to pull out of venture fund with Renault in cost-cutting drive, insiders say

TOKYO — Nissan is likely to pull out from a venture capital fund it runs with alliance partners Renault and Mitsubishi Motors, as part of the Japanese automaker's drive to cut costs and conserve cash, two sources said. Nissan will formally take a decision on whether to leave the fund, Alliance Ventures, by the end of this month, the two Nissan insiders told Reuters, declining to be identified because the information has not been made public. The likely move comes after Nissan's junior partner, Mitsubishi Motors Corp, told an alliance meeting last week that it would no longer continue to inject money into the fund, one of the sources said. The decision to leave the Amsterdam-based fund was all but a done deal, the other source said, adding: "Of course we're out. The house is on fire." A Nissan spokeswoman said it was speculation and declined to comment. A Mitsubishi spokesman said no decision had been made. The move comes as Nissan — which has seen its earnings slump — is now facing a downturn in China, its biggest market, due to the impact of the coronavirus outbreak. China sales plunged 80% last month. It also highlights the extent of the automaker's cost-cutting under new CEO Makoto Uchida, who is under pressure for a quick turnaround. Alliance Ventures is aimed at finding "learning opportunities" for the alliance through investing in startups, and is supposed get up to $200 million (153.3 million pounds) a year from the three alliance partners, although it never achieves that full amount, the first source said. It was set up under former alliance head Carlos Ghosn, whose dramatic arrest in Japan culminated in an escape to his childhood home of Lebanon in December. Ghosn faces multiple charges in Japan, including of under-reporting earnings and misappropriation of company funds, all of which he denies. According to its website, the fund was set up with a $200 million initial investment and aims for up to $1 billion by 2023. Portfolio companies include WeRide, a Chinese robo-taxi startup and Tekion Corp, a cloud-based retail platform for cars. "It wasn't established by Ghosn as a way to make money. It was for those learning opportunities we get from investing in smart startups," the first source said. "But given the tough financial situation we are facing, we are looking at investment return."

10 automakers sued over keyless ignitions

Keyless ignition has rapidly proliferated throughout the auto industry to become a fairly normal feature on new cars. It's supposed to offer the convenience of keeping the fob in your pocket and just pressing a button to drive away. However, ten major automakers are now being sued in US District Court over claims that the system is dangerous, Reuters reports. The suit alleges that people are forgetting to shut off the engine, and the lack of an idle timer is the cause for 13 deaths by carbon monoxide poisoning and multiple injuries. The suit currently includes 28 plaintiffs, according to Reuters, but the lawyers are asking for class-action status to potentially add many more. The case goes after a major swath of the industry, including BMW, Daimler, FCA, Ford, General Motors, Honda, Hyundai, Nissan, Toyota, and Volkswagen, plus their related brands like Acura, Infiniti, Mini, and Lexus. In all, over five million vehicles are affected. The assertion here is that people walk away from their vehicle without shutting it off because they believe the engine shuts off automatically. If parked in a garage, carbon monoxide can build up, leading to poisoning. The lawyers claim automakers know this is a problem and also cite 27 complaints to the National Highway Traffic Safety Administration about the issue, according to Reuters. The plaintiffs are asking for an automatic shut-off and damages from the companies. These concerns have come up before, though. Toyota previously faced a lawsuit over a carbon monoxide death after a woman accidentally left her Lexus running. Also earlier this year, GM recalled 64,186 examples of the 2011-2013 Chevrolet Volt because owners weren't shutting them off. The problem resulted in two injuries, and the company released a software update to limit the idling time.
