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 again staring down another $1.8B in hedge fund lawsuits

The sequence of events from 2007 that began with Porsche's secret attempt to take over Volkswagen, and instead lead to Porsche being taken over by VW, continues to instigate lawsuits against the Stuttgart sports car manufacturer. A group of hedge funds that suffered over $1 billion in losses sued the car company in New York. Porsche had publicly stated it wasn't trying to buy VW, the hedge funds in question were shorting VW stock, and when Porsche's actual intentions were revealed, the stock shot up and the hedge funds took a beating.
The case was thrown out over the issue of jurisdiction, then appealed, only to see another suit filed on top of that. After that, most of the hedge funds withdrew their claims in New York and Porsche offered a 90-day window to refile in Germany where it is already fighting a number of other suits over the same issue. The hedge funds accepted the offer, refiling in Stuttgart for $1.8 billion in damages. According to Bloomberg, Porsche hasn't commented on the refiling, but as the same plaintiffs are involved, it's safe to assume that the carmaker still feels the case is "unsubstantiated and without merit." It has fared alright so far even in German courts, with two lesser cases against it thrown out last year.

Porsche close to fix for 911 GT3 engine fires

It looks like 2014 Porsche 911 GT3 drivers might actually get to drive their cars again soon. Reports of fires affecting the track-ready Germans first began about a month ago. Then, a few days later, the automaker confirmed two of the five alleged blazes and said owners shouldn't drive their cars until further notice. Porsche then went so far as to offer to pick up the GT3s and transport them to the nearest dealer until the problem was identified and a fix was found. Finally, there appears to be a repair.
"We know the reason and the problem-solving measures. We're testing them," said Porsche CEO Matthias Müller to Bloomberg. The technical fix will be released to owners shortly.
The recall affects all 785 GT3s that have been sold so far, but there have been no reported injuries caused by the fires. When it first announced the safety campaign, Porsche said: "Internal studies to determine the cause of the engine damage have not been completed yet."
