10 Years of Porsche Bliss

Posted by Carlton Bale on 25th July 2008

10 years ago today, on July 25, 1998, I took delivery of my 1999 Porsche Boxster. During that time, I've experienced 43,000 miles of top-down convertible bliss. My rule-of-thumb is that it should be driven only with the top down. I don't want to be one of those top-up-on-a-beautiful-day people. Early each year, I look forward to first clear day above 40 degrees so that I can put the top down, the collar on my jacket up, the heated seats on, and enjoy the brisk prelude to spring.

I've been determined to keep the car throughout the changes in life that typically cause owners to part with their toys. Luckily my wife feels as strongly about keeping the car as I do (it provided us transportation for our first date.) So it's stayed despite the fact that I've gotten married, moved, and had a kid.

The two competing parts of my personality are sentimental attachment and the need to upgrade to the latest technology. So far, the sentimental (and financial) forces have won out. Still, someday, I could envision replacing my aging model with one that offers vehicle stability control, a dual clutch transmission, more powerful engine, and upgraded electronics. But for now (perhaps for another 10 years?), I'm happy with the Boxster I have. Unless I figure how to keep my current vehicle and make room in the garage for a new one. . . (a win-win for those competing forces.)

Porsche PDK Dual Clutch Transmission Arrives

Posted by Carlton Bale on 25th July 2008

The one performance technology that has been lacking from Porsche vehicles is a dual clutch, electronically controlled manual transmission. The wait is now over. Porsche was the first to develop this technology (about 25 years ago) but one of the last performance brands to implement it. Below is an excellent video explaining how it operates, but the benefit is instantaneous upshifts and downshifts with perfect engine speed matching. It will be available in the Model Year 2009 911 and 2010 Boxster/Cayman.

Some additional details:

  • This is a 7-speed transmission. 7th gear being is an overdrive gear for fuel economy.  Max speed is obtained in 6th gear.
  • The accelerator pedal has a switch that detects when the foot pedal is floored.  When this switch is depressed, the transmission immediately shifts to the lowest possible gear to achieve maximum acceleration.
  • There is an upshift/downshift switch on both the left and right side of the steering wheel. Pushing the front side of the sliding switch forward with your thumb causes an upshift.  Pushing it backwards (from the back of the steering wheel) with your index finger causes a downshift. (I believe I got those directions correct.)
  • There is a manual mode that is engaged by moving the gear selector sideways. This causes full manual control with no automatic gear shifting.
  • The automatic mode works so well that you don't need to use manual mode, even when on the track.
  • Even in fully automatic mode, the buttons on the steering wheel can be used to momentarily upshift and downshit to different gears.
  • The Sports Chrono Option allows faster gear changes that enhance performance but are not quite as smooth. It also allows a launch mode to perfectly modulate the clutch for maximum acceleration with minimal wheel slip, producing the fastest 0-to-whatever speed possible.
