Porsche Cayenne, Panamera production halted by flooding

If you recently ordered a Porsche Cayenne or a Panamera, delivery may take a little longer than originally expected. Automotive News reports that production of both models has been temporarily halted at the Porsche assembly plant in Leipzig, Germany as the result of supply shortages caused by flooding in the nearby Czech Republic. The reason for the stoppage is that the body of the Cayenne - currently Porsche's best-selling model - is produced at a Volkswagen plant in the Czech city of Bratislava and shipped by train to Leipzig.
The report does not indicate why Panamera production has been stopped - that the five-door's body is made at a separate location in Hanover, Germany. However pre-assembly will continue on these models. At full capacity, the Leipzig plant can produce about 450 vehicles per day, and it isn't clear how long this weather-related stoppage will last.

VW could fight Uber Black with Porsche and Audi vehicles

Last week, the Volkswagen group dumped $300 million into Gett, a taxi hailing-cum-ride sharing app that's big outside of the US. Now, the company has revealed that it's pondering a rival to Uber Black by offering private drivers access to its higher-end vehicles. Details are scarce since it's a single line reference in a very long press release, but VW says that it's looking at a "special chauffeur service" that features "premium brands, such as Audi and Porsche." What that looks like in reality is anyone's guess, although the idea of getting ferried around in an Audi RS 7 does have some appeal. The deal with Gett will concentrate on getting Volkswagen cars into the hands of Gett's drivers with the promise of juicy discounts. For instance, the firm will offer a special package that'll bundle car insurance and servicing with the purchase price, which can be paid by a would-be operator in installments. It's a similar deal to the one that Uber offers would-be drivers, letting them buy cars from manufacturers like Volkswagen, Ford and Toyota at a discount. Uber, however, also lets prospective cabbies rent their vehicle on a monthly basis, thanks to a deal with Enterprise. Both of which will likely become more muscular now that Uber has a further $3.5 billion in its back pocket. The troubling fact for the auto industry is that people will still need cars, but it's likely that they won't need as many as they do right now. On-demand services and self-driving vehicles are, after all, intended to shuttle around cities like an ersatz taxi-cum-metro system rather than sitting in parking lots. The concepts of ownership that we currently hold dear (and the profits that car companies get from them) are likely to fade away in the next, say, fifty years time. As such, conglomerates like VW will have to reinvent themselves as both manufacturer and transport company in one. But these changes are never easy, especially when the biggest car firms have tons of baggage that slows down their progress. Many are still devoting time and resources to producing thousands of new cars with combustion engines that will be on the roads for years to come. Looming in the shadow, however, is the emissions scandal, with the financial and reputational penalties likely to be felt for years to come. Younger, more nimble rivals without legacy businesses, like Tesla, are working on mass-producing electric cars for mass-market prices.

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.
