Is Porsche planning a GT5?

A trademark application filed in Europe suggests Porsche could be planning a GT5 model to slot at the bottom of its track-focused sports car lineup. The German automaker's GT skunkworks division in Weissach earned its reputation with enthusiasts producing the GT3 and GT3 RS versions of the 911, and previously offered GT2 and even GT1 models as well (although the latter was a limited homologation special). It recently extended itself slightly downmarket with the launch of the Cayman GT4, but this trademark application – already reportedly accepted in Germany and currently being reviewed by the European office – suggests an even more accessible model could be on its way, Autocar reports. Just what form a GT5 would take, however, remains a mystery. The numerical progression would suggest that Porsche is planning a hardcore version of an even smaller sports car, if such a project ever got off the ground to slot in below the Boxster and Cayman. Given that the 911 has bred both GT2 and GT3 versions, Weissach could alternatively be planning an additional GT version of the Cayman, or planning a hardcore version of the Boxster. The prospect of a GT5 version of the Macan, Cayenne, or Panamera seems unlikely as the alphanumeric designation has never been applied to anything other than a two-door coupe, but then we never really know what the future will bring: Before 2002 Porsche had never done anything with more than two doors altogether. These designations are typically borrowed from their corresponding racing class, and of course there is no GT5 category. But then most of these racing classes have been amalgamated into GT3 anyway, unless Porsche is planning on using the name for its own entry-level spec racing series. But at this point we're just spitballing. It's just as likely that the company has simply filed the trademark application to keep its options open for the future. Related Video:

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.

Motor Trend puts Chevy Camaro Z28 and Porsche 911 GT3 Head 2 Head

Motor Trend admits, "This is an unfair comparison." But that doesn't make it any less fun to watch when they pit a Camaro Z/28 against the Porsche 911 GT3. The former has a 7.0-liter V8 with 505 horsepower and 481 pound-feet of torque shifted through a six-speed manual. The latter has a 3.8-liter flat-six with 475 hp and 324 lb-ft shifted through a seven-speed dual-clutch transmission. Yet those are only the little disparities – the big disparities are mass and money: the Camaro weighs 3,882 pounds and costs $76,150 as-tested, the Porsche weighs 3,267 pounds and costs $145,785. But they're both about hardcore performance, so MT takes them out on the street, to the drag strip, to the parking lot for figure eights and a skidpad test, and finally to Big Willow for Randy Pobst to give his professional assessment. Remember when a lotta people spent a lotta time debating Pirates vs. Ninjas? This is like that, only it's the "haul-ass good-time car" vs. the "track surgeon." Enjoy the debate in the video.
