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.

There's a Porsche Cayman under here somewhere

What we have here is the work of Dubai tuner Royal Customs that is controversial even beyond its styling. The Middle East aftermarket house says it spent fourteen months developing a bodykit for the Porsche Cayman, and the results seem to be aimed at those who wish their coupe were a 918 Spyder - the nose, strake-filled and widened rear fender, carbon fiber wing and massive diffuser all cribbing some from Stuttgart's new hybrid supercar.
Even without a buyer, the Alpha One Concept is already controversial. When WorldCarFans posted on the Royal Customs car recently, German tuner Alpha-N Performance wrote in alleging that the Dubai package copies their design from two years ago, which was also called the Alpha One, a design with which it's clear the Dubai Alpha One shares numerous cues. We asked Royal Customs about its relationship to the Alpha One car, we were told, "Yes, there is a lot we can say about the remarkable similarities all of which will be explained by our press release by Mr. Emil from Autogespot. Please wait for the official release and you will have the full exciting story. It's an 'actual success story' and not a 'replication' story."
The response is referring to an "extensive report" on the car coming out of Autogespot. Royal Customs doesn't have the Alpha One Concept on its site yet, so we're still missing quite a few details on it, such as whether the Porsche engine has been given a similarly 918-ish workover. We do know that the company says each car takes 30 days to build and it will only build three of them, which is a number that should satisfy any haters and, even more so, its buyers. You can decide which side of the fence you're on by having a close look at it in the gallery above.

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.
