How did Nissan tweet a response to the Royal Baby announcement so quickly?

A mere seven minutes after the Duke and Duchess of Cambridge announced they were pregnant with their second child, Nissan had the perfect post circulating on the Twittersphere. How did Nissan know to expect Kate and William were expecting? By paying attention to the Internet zeitgeist.
It could be triplets and there would *still* be enough room for the Queen... #XTrail #SevenSeats #RoyalBaby pic.twitter.com/k4HiNAb7lq

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.

Ghosn: 'While I'm proud of our EV leadership, I know it's not enough.'

Renault-Nissan CEO Carlos Ghosn has written something like a State of the Union on electric vehicles and the carbon economy. We'd sum it up as, 'we're working on it but we all need to work harder.' Ghosn believes all of the commitments made at the Paris COP21 climate change conference are a start, but "the support of the business community is imperative," in coordination with the public sector. He stresses that he's after an "orderly transition," one that uses what we have now in order to go where many believe we need to go. That means no threats or revolution, no "aggressive government intervention and centralized demand and control," but rather a "practical, affordable way to begin reducing dependence" on the fuel that turns the skies brown. Ghosn wraps up his manifesto this way: "The UN Secretary General recently said that we are the first generation to feel the effects of climate change and the last to be able to do anything to stop it. This is a call to action, and the auto industry is committed to doing its part." Based on the undeniable shift toward the electrification of the automobile, we know that the call is being answered. Given the limited market share EVs have today, it could still use some more people and companies picking up the phone. With vehicle numbers expected to grow from 800 million to more than two billion by 2050, "transition will occur one way or another," Ghosn writes. Head over to Forbes to read Ghosn's thoughts.
