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.

PSA shares rise following FCA's breakup with Renault

Shares in Groupe PSA, parent company of automakers Peugeot, Citroen and the DS brand, rose on Thursday as analysts considered the possibility that Fiat Chrysler could turn back to PSA after withdrawing its $35 billion merger offer for Renault. "Both parties have acknowledged the need for scale or [mergers and acquisitions] and may pursue other opportunities. If Nissan was an obstacle (to an FCA-Renault deal) PSA-FCA discussions could resume," wrote brokerage Jefferies. Back in March at the Geneva Motor Show, rumors started swirling that PSA was interested in a potential merger with FCA. Mike Manley, who took over at the helm of Fiat Chrysler following the death of Sergio Marchionne, had indicated a willingness to look into potential partnership options. Of course, that was all before FCA proposed a merger with Renault — with that deal now off the table, attention naturally turns back to PSA, which is also based in France. "We expect both shares to react negatively but see FCA having wider strategic options and Renault shares more downside risk near-term," said Jefferies. According to Reuters, PSA shares were up 1.5% at the time this was published, making it the top-performing stock on France's benchmark CAC-40 Index. Renault saw its shares slump 7%. Shares for FCA fell 3% in early trading on the Milan Stock Exchange. Considering that FCA said in its statement confirming the withdraw of its merger offer with Renault that "political conditions in France do not currently exist for such a combination to proceed successfully," we have to wonder how keen the company is to begin negotiations with another French automaker like PSA. Those thoughts were similarly voiced by Bernstein Research analyst Max Warburton, who said (via Forbes), "Expect PSA to rise on unrealistic hopes it may be FCA's next date."
