Here is the Nov C+D. Wow.
From Road and Track November. This '07 Turbo had the Tiptronic...and blasted an 11.6 in the 1320...and 3.3 0-60. Great numbers.
Porsche 911 Turbo
Porsche’s Tiptronic electronically controlled automatic transmission makes the 2007 911 Turbo quicker down the drag strip.
It’s been a long-standing tradition that true sports cars are equipped with manual transmissions, putting the driver in full control and enabling him to extract the utmost from his machine. Things have changed: Computers can simulate logic, and machines can manipulate things more accurately and quickly than humans. Clutch pedals and stick shifts are giving way to buttons and paddles. Increasingly, the automobile is becoming less and less in our control — anti-lock brakes with brake assist and force distribution, yaw and traction control, active suspension, electric steering with variable ratios, active cruise control — all for the better they say. But lost is the necessity for skills that once made racing drivers famous.
It is no surprise that Porsche’s Tiptronic electronically controlled automatic transmission is good, but it is a surprise to learn that it makes the 2007 911 Turbo quicker down the drag strip. Aside from special applications, the torque converter has always been considered a hindrance. In this case the Tiptronic even has one less gear, being a 5-speed. The 6-speed manual on the face of it should clearly out-drag the two-pedal car. Nay, it does not. Power-braking the Tiptronic loads the turbo and builds boost before the car leaves the line. To build boost in the manual-equipped car would require excessive slipping of the clutch. This delay in building boost gives the advantage to the torque-converter-equipped Tiptronic — the gain being a tenth of a second to 60 mph despite its taller first gear.
The ability of the Tiptronic system to quickly shift gears shaves time the whole length of the strip — pulling out two more tenths. This is because the turbo stays under load while the Tiptronic shifts — keeping the 480 bhp at work pushing the car. In contrast, the manual is given pause three times in the quarter- mile as the driver changes gears.
Aside from transmissions, the two cars we tested were identical. The red one is the Tiptronic. The Tiptronic’s shifts are not made with a conventional paddle system. Instead, Porsche opted for rocker-type switches on both left and right sides of the steering wheel, located directly under the thumbs. The rocker switches allow up- and downshifting with either hand.
We know the automatic car is faster, but we still don’t like it. We continue to prefer the traditional method of making a car go fast and hope the art of driving isn’t lost.
