Nismo mashes it up with Sentra 370Z and Altima GT-R

Nismo was a tuning division once content (or required) to restrict itself to just one or two models at a time, but these days Nissan is taking the gloves off and allowing its motorsport department to tune just about everything's it's got.
Now in its thirtieth year, Nismo tunes versions of the GT-R, 370Z, Juke and Versa Note, and will soon be working its magic on the Sentra and European-market Qashqai and Pulsar. And that's not even taking into account its considerable racing programs. At this rate, Nismo is going to run out of vehicles to tune pretty quickly, so what has it done? Invent new ones!
No, we're afraid that Nissan is not letting its Nismo division produce its own stand-alone product, but it has released two sets of amusing renderings combining two vehicles into one. One depicts a GT-R crossed with a Teana sedan (better known in these parts at the Altima), while the other crosses a Sentra with a 370Z.

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.
