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.

2015 Porsche Macan Turbo

The misinformation first started back in May of 2007 - more than six years ago - when word came that Porsche was developing a compact utility vehicle to fill out its product line. Rumors swirled that the German automaker's future "Roxster" would be based on the then-upcoming Audi Q5. By September of 2010, the name had changed to "Cajun," but the vehicle was still expected to be "based heavily on the Audi Q5," said reports in the months that followed. One year later, the first test mules were spotted, the mechanics hidden beneath barely disguised Audi sheetmetal, which did nothing to give the upcoming model its own identity. And even after Porsche announced "Macan" as the vehicle's production name in early 2012, articles stated that it would "arrive on the same chassis as the Audi Q5, though with suspension, brake and engine tweaks suitable to the Porsche range."
It's no wonder that most still consider the all-new Porsche Macan nothing more than a heavily massaged Q5.
To help lift some of the mystery surrounding its latest release, Porsche hosted us in Germany for an in-depth look at its new crossover (while Europeans call it a "sport utility," its car platform allows us to call it a proper CUV). The technology workshop offered us insight to the design and mechanical execution, and it concluded with a short test ride. The trip was both enlightening and educational - and it left us with a whole new perspective on the Macan.

Porsche 356 Outlaw is the other Continental

In Porsche parlance, 'outlaw' basically means 'hot rod,' and that definition can vary from person to person. For Jack Griffin and his 1955 Porsche 356 Continental, it means taking a great car to start with and reworking it to become a classic coupe that fits its driver perfectly. The latest video from Petrolicious highlights Griffin's 356 and all of the personalization he has in the beautiful ride.
Griffin acquired this 356 in 1994, but it came in rough shape. That made it the perfect canvas to transform the coupe into the Porsche of his dreams. On the outside, only things like the hood-mounted fuel filler, louvered decklid and Fuchs wheels give it away as something special, but underneath, it is modernized to be a faster, more robust car. Griffin considers it "a piece of art on wheels."
Hearing the Continental name associated with Griffin's Porsche might be throwing you, since it's normally more associated with Lincoln, but Griffin tells the whole story of what makes it so special on his '55 in the video.
