Luftgekuhlt is an incredible car show for air-cooled Porsches

Air-cooled Porsches: Three lousy words and four lousy syllables. String them together and you get an expensive, emotive cocktail. If you've always wanted to own one, you know that truth, as prices of vintage 356s, 911s, and even 914s have risen steadily and then recently, skyrocketed. That change in the economics of cars once considered workhorses has altered the zeitgeist around what Porsche means to different generations of fans. Back in the day, Porsche didn't strive to be as expensive or as untouchable as Ferrari's metal. As a result, you typically find Porsche owners able — and willing — to twist wrenches on their machines. For one thing, air-cooled cars from Zuffenhausen were relatively easy to maintain and drive in all four seasons. They weren't show ponies. But when cars become collectibles, the scene around them changes, and Porsche FIA World Endurance Championship racer Patrick Long and his longtime pal, designer Howie Idelson, were, as Long put it, sick of meets "at golf courses where you have to worry if your shoes match your pants." Long mixes fine in that world. He's the only American on Porsche's factory team and he's won in everything from ALMS to GT to Baja. That tends to put your loafers at plenty of tony cocktail parties. But Long and Idelson, both SoCal natives who met as kids racing karts, wanted to make something of the air-cooled Porsche car culture, not of the collecting culture. Hence the birth, less than three years ago, of Luftgeku hlt. "It's literally 'air-cooled' in German but has that nerdish, Instagram picture-trading offshoot of a kind of Porsche cult," Long says, noting he's less interested in defining the brand that now sells t-shirts and posters and more interested in keeping things loose.

As such, he was still floored by the recently convened Luftgekuhlt 3, the third party he and Idelson have put on and by far the largest. It was held in the shadow of the L.A. skyline at the headquarters of Modernica furniture. More than 400 air-cooled Porsches and their owners convened. The location was no afterthought. "We wanted people to come for the cars and then be blown away by the venue: It has to be interesting. It has to attract different kinds of people." To spur that, Long doesn't adhere to the strict fealty of precision that's a default at most collector rallies.

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 planning new 911 Speedster as 550 tribute

Some look at the emergence of a new Porsche 911 and see a car. But to Porsche engineers, it might as well be a reset button. Because every time a new 911 comes out, it sets off a tidal wave of new variants to follow, including convertibles, turbos, targas, GT3s... the works.
The next down the pipeline, though, could be one of the most desirable. That, according to German publication Auto Bild, will be a new 911 Speedster. When it arrives early in 2015, the special roadster will reportedly be limited to just 550 examples in tribute to the original 550 Spyder.
It'll reportedly have hidden door handles, a chopped-down windshield and a fabric top to be used only in case of emergency, manually disappearing below a carbon-fiber cowling. All of which makes it sounds as much like a bigger version of the Boxster Spyder as a successor to the last 911 Speedster (pictured above), and that's no bad thing at all.
