Porsche issues stop-sale on Cayenne Diesel in US

As reported yesterday, the ongoing Volkswagen diesel emissions scandal has expanded to the VW Group's 3.0-liter TDI V6 engines. The Environmental Protection Agency's finding implicate many engines used by Audi and Porsche, including Porsche's only US domestic market diesel offering: the Cayenne. And after putting two and two together, Porsche has issued a stop-sale on its US-market Cayenne diesels. Porsche's statement is terse. They refer to the EPA's findings as "unexpected," and stress that its stop-sale order is "voluntary." And Porsche assures owners that they can continue to drive their Cayennes as per normal, like the rest of the VW Group vehicles called into question for NOx emissions. The stop-sale order will remain in place indefinitely, until Porsche can "resolve" the issue. No word as of yet as to what the fix will be for the 3.0-liter TDI engines.

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.

Porsche Mission E set for launch by 2020

Porsche will bring the Mission E electric sedan to production by 2020. The company's board just gave the thumbs up for further development of the vehicle on Dec. 4. "Even in a greatly changing motoring world, Porsche will maintain its front-row position with this fascinating sports car," Dr. Wolfgang Porsche, chairman of the supervisory board of Porsche AG, said in the model's announcement. The Mission E debuted at the 2015 Frankfurt Motor Show as a long-slung sedan in a mix of aluminum, steel, and carbon-fiber reinforced polymer. The concept featured two permanent magnet synchronous motors with over 590 horsepower, all-wheel drive with torque vectoring, and four-wheel steering. Porsche claimed that the model could reach 62 miles per hour in less than 3.5 seconds and offer a 500-kilometer (310.7-mile) range on the European testing cycle. Plus, the brand alleged the vehicle could lap the Nordschleife in less than eight minutes. The concept version also boasted an 800-volt charger to provide 80 percent of the range just 15 minutes after the driver plugged it in. We won't know for some time how much of this cutting-edge tech will actually arrive on the production version, but building the Mission E will coincide with 700-million euros ($765 million) in updates to the Porsche factory in Stuttgart-Zuffenhausen. In the coming years, the company will upgrade its engine factory to assemble electric motors. The automaker will also add a new paint shop, assembly plant, and enlarged body shop there.

It will be launched at the end of the decade. The supervisory board of the Porsche AG today gave the green light for the Mission E project. Mission E, Concept Car, Press Conference IAA , Frankfurt, 2015, Porsche AG With the Mission E project, Porsche is continuing to back sustainable growth. In Stuttgart-Zuffenhausen alone more than 1,000 new jobs are being created. The company will be investing around 700 million euros in its main site there. Over the next few years, a new paint shop and a new assembly plant will be built. The existing engine factory is also being expanded for the production of electric motors. In addition, the existing body shop is being enlarged.
