Google's new Android Autos OS unveiled, will be in cars this year [w/video]

Connected cars are coming en-masse. We know this much. How, though, remains something of an open question, especially as two of the world's largest tech companies are preparing to battle for control of your car's dashboard. On the one hand, we have Apple and its CarPlay system. And now, we know what Google has been working on with Auto Link.
Its new name is Android Auto, and yes, it's based off the Android architecture that is the primary challenger to Apple's iOS mobile operating system. Announced at Google's I/O conference today, Android Auto functions similarly to CarPlay - owners will need to plug their smartphones into their cars to access the full breadth of capability.
In Android Auto's case, that means a wealth of voice controls to limit distracted driving. Google's marquee apps will be available when the interface arrives in production models later this year, including Google Play Music, Google Maps and voice-activated texting and text playback. Meanwhile, developers will be able to begin designing custom apps for the new system via an upcoming software development kit.

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, Renault reveal how they'll reshape alliance to cut costs, regain profit

TOKYO — The auto alliance of Nissan and Renault said Wednesday it will be sharing more vehicle parts, technology and models to save costs as the industry struggles to survive the coronavirus pandemic. Alliance Operating Board Chairman Jean-Dominique Senard said the group, which also includes smaller Japanese automaker Mitsubishi, will have each company focusing on geographic regions. “There is no plan for a merger of our companies,” the chairman said. “Our model today is a very distinctive model ... we donÂ’t need a merger to be efficient.” He stressed the alliance needs to adjust to the “unprecedented economic crisis,” to pursue efficiency and competitiveness, not sheer sales volumes. “Now is the time to rebuild,” Senard said, making clear he believed the alliance remained strong. All automakers are suffering from the pandemic, and scaling back or suspending production, but Nissan was reeling before the crisis struck from a scandal involving its former chairman, Carlos Ghosn. Yokohama-based Nissan is due to report its annual results on Thursday and has forecast it will slip into its first yearly loss in 11 years. Under the latest so-called leader-follower initiative, Nissan will focus on China, North America and Japan; Renault on Europe, Russia and South America and North Africa, and Mitsubishi on Southeast Asia and Oceania, for the benefit of the entire alliance. Nissan Chief Executive Makoto Uchida said the alliance planned to pursue fiscal strength together. “The synergy is huge,” he said. The number of vehicles sharing the same platform will double by 2024, saving 2 billion euros ($2.2 billion), according to Senard. The shared technology will also include electric cars and autonomous driving, platforms and car bodies, the executives said. Nissan is a leader in electric cars with its Leaf, but such technology will be available to the other alliance members, they said. The companies gave few details of how the revamp would deliver in the short term, as the car industry grapples with the fallout from the coronavirus pandemic and pressure to develop less polluting vehicles. They said in a joint statement that they aimed to produce nearly half of their vehicles under the new leader-follower approach by 2025 and hoped to cut investment per model in the scheme by up to 40%. The range of vehicles they produce is expected to fall by 20% by 2025 though the firms did not say how many jobs would go as they shift production.
