Porsche recalling Macan S and Turbo for fuel leak

Porsche is recalling 58,881 examples of the Macan S and Turbo worldwide because of a possible leak in the low-pressure fuel line in the engine compartment. Of these, there are 21,835 affected in the US and 3,490 in Canada. According to the German automaker, this campaign is "a purely precautionary measure" because there're no reports of any accidents or injuries from the flaw. As a fix, dealers will replace the fuel line, which will take around an hour. Porsche will contact owners directly to arrange for the service. The company discovered the issue "after a precise examination of complaints," according to its statement, and corrected the problem for units in production. Porsche Examines Macan S and Macan Turbo Vehicles October 30, 2015 Possible leak in low-pressure line – affected customers will be contacted directly Atlanta, Georgia. Voluntary safety recall: Porsche is conducting an examination of 58,881 Macan S and Macan Turbo vehicles around the world, of which 21,835 are in the United States and 3,490 are in Canada. The reason for this move is a possible leak in the low-pressure fuel line inside the engine compartment. The line will be replaced in the workshop. This is a purely precautionary measure, as there have been no reports of accidents or injuries as a result of this concern. The problem was identified after a precise examination of complaints and then immediately rectified in ongoing production. Owners of the vehicles will be contacted directly and workshop appointments will be arranged as quickly as possible. The work will take approximately one hour and will be carried out free of charge.

Driving the million-mile Porsche 356

Maybe you've seen or heard about the Porsche 356 with almost one-million miles (though it doesn't look like it), but Petrolicious finally has produced a video to show us what it's like to drive the 982,000-mile car. Guy Newmark's beautiful, dark-blue 1964 356C looks great in motion - much better than in photos - and serves to remind us not only what meticulous car care can do for old classics, but that old Porsches were built to last.
So how fastidious is Newmark about maintaining it? He takes the car to his mechanic of 40 years every 3,000 miles for an oil change and to fix anything that needs attention.
Newmark says his 356 "is everything you could want," and that he finds errands to do just to go drive it. We would, too. The next-best thing is to watch the inspiring video below of the well-traveled Porsche.

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.
