Official Porsche numbers are different....
0-60 mph 3.4 seconds (tip)
0-62 mph 3.7 seconds (tip)
0-62 mph 3.9 seconds (manual)
Christophorus is saying 3.7 seconds because they use metric sytem.... 0-62 ( 0-100km)
0-60 mph 3.4 seconds (tip)
0-62 mph 3.7 seconds (tip)
0-62 mph 3.9 seconds (manual)
Christophorus is saying 3.7 seconds because they use metric sytem.... 0-62 ( 0-100km)

It's pretty simple to figure out why the Tip is faster - it has a 5-speed gearbox whereas the stick has a 6-speed gearbox. It means the Tip hits 60 in 1st gear, not 2nd as in the stick version. Of course if the Tip was a 6-speed it would be a different story...

Why the tip is faster (once again)
Technical Q&A: 911 Turbo Page 1 of3
Technical ~M: 911 Turbo
The announcement of the new 911 Turbo with its spectacular Variable Turbine Geometry and ground
pounding horsepower figures has many enthusiast customers asking questions. With some assistanc
from Germany, we’ve gathered answers on some of the most interesting points about this new PorscF
vehicle:
Q: Lots of Porsche consumer chatboards are buzzing with the spec seen in the
911 Turbo initial release: the Tiptronic version of the 2007 911 Turbo accelerates
0.3 seconds faster to 0-60 mph compared to the manual transmission version. Is
this correct?
A: Yes, it is. Due to the new variable turbine geometry (VTG) system and improved engine control
technology, in addition to mechanical and electronic Improvements in the Tiptronic S gearbox, the
Tiptronjc S version is slightly faster to 60 miles per hour.
Q: How does the 2007 Porsche 911 Turbo equipped with the optional 5-speed
Tlptronic S automatic transmission accelerate faster to 60 mph?
A: The optimized interaction between the new all-wheel-drive system, Porsche Traction Managemen
(PTM), Tiptronic S five-speed automatic transmission, and Tiptronic-specific calibration of the engine
management controls and associated variable turbine geometry (VTG) system, allows the new 911
Turbo with Tiptronic S to accelerate slightly quicker than models equipped with the manual 6-speed
transmission.
Technical Q&A: 911 Turbo Page 2 of 3
Improvements to the Tiptronic S transmission in the latest 911 Turbo contribute to the performance
gains. These include:
1. Earlier ramp-up of boost pressure when ‘brake-torqujng’ the transmission
2. Increased torque build-up allowed when brake-torquing
3. Reduced shifting- and reaction times
If launched appropriately, a 911 Turbo equipped with Tiptronic S is essentially “pre-tensioneci” at the
starting line, and during acceleration runs, power-interruptions are reduced in comparison to the 6-
speed manual transmission. Aiding acceleration, when paired with Tiptronjc S, the all-wheel-drive
system with PTM can deliver a nearly uninterrupted flow of torque to all four wheels.
0: How does this compare with “launching” the manual gearbox 911 Turbo?
A: With the manual transmission, engine boost pressure needs to build after clutch engagement, whi
can require several fractions of a second. Additionally, clutch- and wheel-slip when launching from a
standstill can also make it difficult to translate engine torque into the quickest acceleration times.
In terms of providing performance to our customers, the Tiptronic S transmission has made the
prodigious abilities of the 911 Turbo more accessible to a wider range of customers. In its evolution, tl
Tiptronic S now provides certain areas of strength in relation to the 6-speed manual, particularly in
standing start acceleration numbers, an area of quantified performance that grows more challenging E
peak horsepower levels continue to escalate.
For those wishing to challenge themselves on a racetrack, and who prefer the control and selection ol
the 6-speed, the manual gearbox will remain the transmission of choice.
Q: Tell us more about the history of VTG. Is the 2007 Porsche 911 Turbo the first
production gasoline-fueled vehicle to incorporate variable turbine geometry?
A: Successfully, yes. Porsche’s variable turbine geometry (VTG) setup on the 2007 911 Turbo was
developed in close cooperation with Borg Warner Turbo Systems, and is based on technology that ha
been widely and successfully applied to diesel engines since the early 1 990s.
It is also nearly identical in concept to other turbo manufacturers’ variable nozzle/geometry
compressors, including a system that was briefly used on a series gasoline production engine in the
late 1 980s. This application encountered difficulties due to high operating temperatures---a problem n
easily solved with the materials technology of the day---and production was stopped after a limited rw
0: So why is this Turbo’s use of VTG going to be more successful?
A: After nearly two decades, aerospace-grade materials have allowed the progression of variable
turbine geometry technology to the point that it can now reliably operate in the higher-temperature
environment of turbocharged gasoline engines. Porsche’s version of variable turbine geometry in the
2007 911 Turbo incorporates these latest material applications, plus a sophisticated control algorithm
The combination produces the advantages of both small and large turbochargers, generating a much
wider plateau of torque and providing quicker response compared to the previous generation 911 Turbo, while providing the reliability of fixed-vane turbochargers.
As noted, the variable turbine geometry (VTG) system on the 2007 911 Turbo is also based on widely
and successfully applied turbodie~~l technology, which further underscores the reliability of the
Concept.

Your last statement is un-enlightened.
