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.

Ferrari IPO may turn out to be good news for enthusiasts

Sergio Marchionne's strategy to spin off Ferrari from FCA and make the Italian automaker a publicly traded company has been met with ire from a vocal contingent of enthusiasts ever since rumors about the plan began to surface a few years ago. Some of these particularly pessimistic automotive pundits have voiced fears that with stockholders in the mix, it would not only spell the demise of the exclusive Italian supercar maker as we know it, but would in fact "ruin" the company. Call me dense, but I fail to see what the issue is. That isn't to say that I don't understand what's causing the fear. When profitability becomes a higher priority for a brand that's historically relied on exclusivity to keep its products in the highest echelons of desirability, there's a high potential for internal philosophical conflict. And then there are concerns about the sorts of products that Ferrari might develop that aren't the high-performance sports cars that the brand is known for. But individuals with those apprehensions seem to forget that Ferrari has already lent its name to a multitude of things that are not LaFerraris, 488 GTBs, or F12 Berlinettas, including clothing, headphones, and even laptops. But let's assume for a moment that the core anxiety is about future vehicles – including the unspeakable notion that Ferrari might develop an SUV. Why wouldn't Ferrari build an SUV, especially after seeing how incredibly successful that endeavor has been for Porsche? I think it's likely that Ferrari will put engineers to task creating some sort of crossover or high-rolling cruiser with room for the whole family at some point in the near future. And why wouldn't it, after seeing how incredibly successful that endeavor has been for Porsche? After all, the Cayenne accounted for more US sales in 2013 than the Boxster, Cayman, 911, and 918 combined, and it only gave up about a thousand units of sales last year to make room for the Macan crossover, the latter of which Porsche sold nearly as many of as it did Boxsters and Caymans. People want these vehicles, and they're willing to pay quite a bit of money for them. If we use Porsche's recent trajectory as a foreshadowing metric for what's in store for Ferrari, the future actually looks pretty good. After all, those SUV sales keep plenty of cash in Porsche's coffers for the low-volume projects that we enthusiasts love, like the 918 Spyder and the 911 GT3 RS.

Magnus Walker drives 911 Turbos old and new

It's been forty years now since Porsche released the original 911 Turbo. And as many things that have remained a constant, a lot has changed, too: the engine has gone from air-cooled to liquid, moved up to nearly a midships layout, and drives almost exactly double the original's output to all four wheels instead of just the back set through a seven-speed dual-clutch transmission instead of a five-speed manual. It'll also reach highway speeds about twice as fast as the original. That's progress for you, and who better to compare Porsche Turbos old and new than Magnus Walker. The outlaw of the 911 scene may not look the part, but to those in the know, he's got the last word when it comes to Porsches. After searching for some time, Walker recently got his hands on a cherry of an original 930 Turbo from 1975 – the first year it was made – and had it shipped from Australia to California to add to his collection. eGarage caught up with Walker and brought along a new 991 Turbo for juxtaposition. Fortunately it also brought along a video camera or two to document the experience, so check it out in the latest video above.
