Take a POV hot lap in the Porsche 918 Spyder

That title about says it all. This is a hot lap of the Circuit of the Americas in Austin, TX, with Porsche Works Driver Patrick Long at the wheel of a Porsche 918 Spyder. The camera is basically showing us everything that Long sees, making this not just one of the coolest 918 videos we've seen, but also one of the neatest laps of CoTA.
As Long peers through the bends, so will you. You'll see him fight the wheel, and find out just how difficult it is to hustle this hybrid hypercar around a world-class track at speed. It's pretty darn entertaining. There are also a few scattered shots of the 918's exterior just to break up the interior awesomeness, although we aren't exactly complaining about those. Take a look below for the short video from Porsche.

Porsche tells 2014 911 GT3 owners to park their cars pending inspection

Porsche may have have a serious problem on its hands. After a rumored five 2014 911 GT3 coupes caught fire in recent weeks, Porsche launched an investigation and stopped delivering its road-ready racecar until it could diagnose the problem. Now, it has issued a press release asking all 2014 911 GT3 owners to immediately stop driving their cars until they can be inspected. Porsche is offering to pick up the cars from owners' homes and take them to the nearest dealer.
Porsche confirms that the at least two 911 GT3 coupes them have caught fire in Europe, and it has elected to inspect all 785 2014 GT3s worldwide. However, it claims no drivers have been injured in the fires. Unfortunately, Porsche says, "Internal studies to determine the cause of the engine damage have not been completed yet," so owners might have a bit of a wait before they are able to drive Porsche's ultimate 911 again. Scroll down to read the entire press release.

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.
