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 revisits its remarkable SC East African Safari rally car

Porsche and motorsports just seem to go hand-in-hand. The brand has defined itself by its ability to compete on the track with the concept that racing bred better road cars. While we are used to seeing 911s speeding along circuits around the world, the rear-engine icon's success in rallying is somewhat less well known. The Porsche Museum aims to fix that by highlighting a 911 SC that competed in the 1978 East African Safari Rally.
The 911 rally car definitely projects a '70s vibe. You wouldn't see too many racecars with a pink brush bar sliding through the stages these days, but it looks amazing. Its bank of spotlights and two, giant, hood-mounted horns definitely give away the car's purpose. Best of all, that fantastic Martini livery defines the looks of Porsche racers from this era.
The 911 SC performed well in the East African Safari Rally, but some suspension damage meant that this particular one never raced again. It's been a part of the Porsche Museum ever since. Scroll down to learn a little more about one part of the brand's off-road legacy.

Porsche offers detuned Boxster and Cayman 211 in Europe

Looking at a new Porsche Boxster? First of all, we commend you on your choice, because in its latest iteration, the Boxster has sped out from under the shadow of the 911 and into its own. But now to choose: do you get the base model with 265 horsepower, the Boxster S with 315 hp, or the top-of-the-line Boxster GTS with 330 hp? It's a daunting question, considering the $10k+ price gap between each model that you could put into the gas-and-rubber jar. Same goes for the Cayman, albeit with ten more horses across the board. But as if that's not confusing enough, there appears to be another player on the field. (That is, at least, in certain European markets.)
Appearing on the company's Belgian and Norwegian sites are the Boxster 211 and Cayman 211. As you might have guessed, they pack a less substantial 211 horsepower, undercutting what we know as the base models. Instead of using a smaller engine, though, the Boxster and Cayman 211 get the same 2.7-liter boxer six, just with less power.
As a result, they're a bit slower off the line: the Boxster 211 takes between 6.1 and 6.4 seconds to get to 62, depending on exact specifications, compared to the 5.5- to 5.8-second range for the 265-hp Boxster, while the Cayman 211 is quoted at 6.2 seconds versus the 275-hp Cayman's 5.4 to 5.7 seconds. Fuel consumption and emissions, on the other hand (and as you'd expect), are better in the 211. But while Porsche Norway charges around $10k less for the 211 models, Porsche Belgium charges the same for the 211 models as it does for the next most powerful versions (from which they appear to be visually indistinguishable).
