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.

$1.4B hedge fund suit against Porsche dismissed

Investors have canvassed courts in Europe and the US to repeatedly sue Porsche over its failed attempt to take over Volkswagen in 2008 (see here, and here and here), and they have repeatedly failed to win any cases. You can add another big loss to the tally, with Bloomberg reporting that the Stuttgart Regional Court has dismissed a 1.4-billion euro ($1.95B US) lawsuit, the decision explained by the court's assertion that the investors would have lost on their short bets even if Porsche hadn't misled them.
Examining the hedge funds' motives for stock purchases and the bets that VW share prices would fall, judge Carola Wittig said that the funds didn't base their decisions on the key bits of "misinformation," and instead were participating simply in "highly speculative and naked short selling," only to get caught out.
With other cases still pending, the continued streak of victories bodes well for Porsche's courtroom fortunes, since judges will expect new information to consider overturning precedent. If there is any new info, it could come from the potential criminal cases still outstanding against former CEO Wendelin Wiedeking and CFO Holger Härter, who were both indicted on charges of market manipulation.

Matt LeBlanc nearly runs over cameraman during Top Gear shoot

Matt LeBlanc almost caused a bad start to the new season of Top Gear when the former Friends star narrowly avoided running over a cameraman. The new host reportedly needed to take a few hours off afterward to get his head together, according to The Mirror. An unnamed Top Gear insider tells the British tabloid that the near tragedy happened while filming in South Africa last month. During a break in the action, LeBlanc decided to take a drive in a Porsche that the show was reviewing. What he didn't realize was that a cameraman was laying on the ground shooting static footage sports car. Another cameraman saw what was happening and got LeBlanc's attention to avert the crisis. "It was one of those instances where, if the tracking man and Matt had reacted even a few seconds later, it could have been really serious. Both of them appreciated what a lucky escape it was," the source told The Mirror. While everyone was okay, the incident reportedly left LeBlanc upset. He needed to take a few hours off to regain his composure and checked to make sure the cameraman wasn't injured. Top Gear announced LeBlanc as a new cast member in February, and welcomed him with a drive in a convertible Reliant Robin, which wore a Stars and Stripes paint scheme. The show's recent trailer highlighted more of LeBlanc's trip, and the car definitely had some problems. Top Gear returns in May to televisions in the UK. There's no word yet on a US premiere date.
