Horn, Hackenburg, Hatz to be fired as VW diesel scandal deepens

Volkswagen will sack three more high ranking executives, including the head of its US division, as the company's diesel scandal deepens. Reuters reported Thursday morning that the executives are: Michael Horn, who has led VW's US operations since January 1, 2014; Ulrich Hackenberg, who oversaw Audi's research and development; and Wolfgang Hatz, who was in charge of R&D for Porsche. A VW spokesman wouldn't comment in response to an Autoblog email. The moves come in the wake of longtime VW chief executive Martin Winterkorn stepping down on Wednesday. Volkswagen's board said at the time that it expected more personnel changes to follow. Volkswagen's board is scheduled to meet Friday, and Porsche CEO Matthias Muller has reportedly been named as Winterkorn's successor. The German auto giant was plunged into crisis last Friday when the EPA charged that the company manipulated software in its diesel-powered cars to pass US emissions tests. About 482,000 vehicles in the US are affected, and VW estimates 11 million around the world could have the rigged software. The revelations have prompted outcry from governments and regulatory agencies, and in the US, Volkswagen could face a fine of up to $18 billion. The departure of Horn, Hackenberg, and Hatz is a stunning downfall for three of the company's top and most visible executives. Horn had led US operations for less than two years, taking over from Jonathan Browning, who was well-respected but failed to reach VW's ambitious sales targets. Before overseeing Audi R&D, Hackenberg was hailed as a visionary for work in developing VW's modular architectures, which allow the company to save time and money by building many vehicles off the same chassis. Hatz had led Porsche R&D since 2011 and also was in charge of engines and transmission development for all of Volkswagen.

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 sells final 918 Spyder amidst excellent year of sales

2014 has been a banner year for Porsche, as the company has moved over 169,000 units through November, an increase of around 12,000 units over the same period in 2013. During last month alone, the company's sales saw a year-over-year jump of 25 percent.

"This strong November is evidence that our strategy is working extremely well," Porsche board member Bernhard Maier said in the accompanying statement. "It also confirms our commitment to taking advantage of every opportunity presented in the global markets." Those notable sales gains aside, this latest sales report comes with some bad news for the overwhelming majority of Porsche fans – the last 918 Spyder has been sold. All 297 cars have been spoken for, with US deliveries set to begin soon. According to Porsche, there are currently around 100 Spyder owners spread across Germany and China. Porsche exceeds previous year's sales by November Last unit of the 918 Spyder sold Atlanta. Porsche AG increased global deliveries to customers from January to November this year to more than 169,000 vehicles, already exceeding the overall total for 2013 of 162,145 new vehicles. This represented a growth of 15 percent over the same period last year (January to November 2013: 147,290 vehicles). In the month of November, Porsche delivered 17,700 vehicles – an increase of one quarter over the same month last year. "This strong November is evidence that our strategy is working extremely well," said Bernhard Maier, Member of the Executive Board – Sales and Marketing of Dr. Ing. h.c. F. Porsche AG. "It also confirms our commitment to taking advantage of every opportunity presented in the global markets." In Europe, Porsche delivered 54,500 vehicles from January to November 2014 – an increase of 18 percent over the previous year, with the domestic German market accounting for 22,200 of the sales. The American region also showed a significant 13 percent increase over last year with a total of 51,600 deliveries. In addition, November announced the finality of sales for the 918 Spyder hybrid super sports car. With a limited run of 918 units, the majority of the cars – 297 – will be shipped from the Zuffenhausen manufactory to buyers in the USA. In both Germany and China there are already around 100 proud new owners who have taken delivery of the super sports car.
