Meet the main man behind the 2014 Porsche 911 GT3

We have yet to catch our breath from our first drive of the 2014 Porsche 911 GT3, but if you're still not sold on the fact that this track-ready 911 is only offered with a PDK transmission, then you should take it up with Andreas Preuninger. Preuninger is the guy who led the team responsible for the latest GT3. Porsche has released a video giving a little backstory of what went into the development of the car, which had as its goal the creation of a pure, rewarding 911 driving experience.
The video captures the sights and sounds of the GT3 perfectly. Perhaps the best part is listening to Preuninger describe one of the defining moments that resulted in replacing the GT3's manual gearbox with the PDK. We don't want to ruin the video for you, so scroll down to check it out for yourself.

Porsche reveals new 911 Turbo Cabriolets, starting from $160,700*

Porsche has come a long way from the days when its entire model line revolved essentially around the 911, but its prototypical rear-engined sports car is still what it's known for best, and still keeps the German automaker pretty busy. With a seemingly endless array of variations on the theme, the 911s just keep on coming until a new generation arrives and then it starts all over again. And what we have here is the new king of the hill (for now, anyway).
Set to debut at the Los Angeles Auto Show a little less than two months from now are the new Porsche 911 Turbo Cabriolets. And no, that's not a typo: that's cabriolets, plural, because what you're looking at are two new models. First up is the 911 Turbo Cabriolet, whose 3.8-liter twin-turbo flat-six develops 520 horsepower, driving the droptop to 60 miles per hour in 3.3 seconds. That's Porsche's claim, and we have a feeling it's a bit conservative. But if that's still not enough, the 911 Turbo S Cabriolet adds an extra 40 hp for a total of 560 to drop the benchmark acceleration run down to 3.1 seconds.
That makes the new topless Turbos 30 horses stronger and 0.2 seconds quicker than the respective models they replace, but the weight penalty involved with replacing a fixed roof with a folding one (and the necessary structural reinforcement) does make the new 911 Turbo Cabs a smidgen more lethargic than their contemporary coupe counterparts, which run the gauntlet in 3.2 and 2.9 seconds in standard Turbo and upgraded Turbo S specs, respectively. They only lose a single tick on the top speed, though, which clocks in at a follicle-tickling 195 mph in either spec. Otherwise the specifications are as identical as you might expect.

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.
