Default top speed

[QUOTE=useridchallenged;6482246]How many of you actually have driven your cars at top speed? I think you're paying for bragging rights if you're focusing on top speed. I've driven both my 996 and 997 (non-S) up to 155 MPH, but I've never found an environment where I could take it all the way to top speed................."

I'm with you; top speed has always beem one of the dumbest specs. I'd love to see some spreadsheet guru start a thread on "Fastest you've driven your 911", but unfortunately I think this would encourage some Turkeys to run theirs up too high plus no telling how much fantasy would be reported.

The question re homolgation is 'How many road going cars do they need to build?' It's not out of the question to think that P-car would build 'X' special road cars to be able to race a few.

Remember BMW had a V8(I think) in a M3 a few years ago, and only promised to build road cars...and never did.

I picked up the April copy of Car Magazine (i.e., the UK magazine). It had an article with much of the same information as Edgy has here -- rear view cameras, etc. As for transmissions, it said that initially a 7 speed manual would be offered along with PDK, and later (i.e., at 991 refresh time) they would offer a CVT and PDK. (This contradicts what I had previously heard -- that the CVT was a long-term replacement for PDK.) At any rate, CVTs are pretty dismal, imo, and I can only hope this doesn't come to be. As for engines, Car had the same info as Edgy has here (minus the top speed info), but it said that Porsche would be using turbos in lower end cars (i.e., like the current day C2 and C2S) as the model evolves. Notably, all of these proposals have something in common -- increased MPG and reduced CO2 emissions.

Oil Dipstick? Too simple. Let's go electronic.
Side-view mirror? Puh-leez...we can overthink that one, too! Let's go digital!

The new of smaller engines, turbos, CVTs - it's not Porsche's fault. The EPA and the Euro greens essentially control the car industry today via environmental mandates.

Ten years from now, we'll all be buying used cars - cars being produced right now - if we want to retain any kind of decent driving experience.

Here is the regulation:
2.1 - Eligibility :
2.1.1 - ACO is the only authority to judge the eligibility of a "LM"
GT2 car.
2.1.2 - Eligibility criteria of a "LM" GT2 Grand Touring car are
made out by the ACO.
2.1.3 - The "LM" GT2 Grand Touring car must meet a minimum
of the following criteria :
a/ To be regularly produced by a manufacturer
approved by ACO ;
Ľ A regular production implies a permanent
implementation of the means required to
produce a minimum of 1 car per week for the
"big manufacturers" and one car per month
to the "small manufacturers". If the
production is not respected, the ACO will
suspend the homologation of the car the year
after. The suspension of the homologation
will cease once the production delay has
been made up. It will be permitted to
compete with the car as soon as a minimum
of 100 road cars for the "big manufacturers"
and 25 road cars for the "small
manufacturers" will be produced.
b/ To have a launch campaign : exhibitions in motor
show, tests with journalists, leaflets with the
technical specifications of the carů
c/ To have a commercial network at its disposal
which provide an after-sales service. An
exemplary of the spare parts' catalogue and the
maintenance manual must be delivered to the
ACO during the homologation of the car.
d/ To be equipped with an engine used in a
production car and made in a quantity of at least
1000 (one thousand) units.
e/ To have a "Full type CEE" homologation or
equivalent for United States or Japan. For the
small manufacturers an official "Low Volume"
homologation for the model of car will be
Ľ Vehicles with a "Low-Volume" type approval
which have not undergone frontal crashtesting
must comply with the F.I.A. frontal
crash-test defined in article 258A-15, with the
weight of the series vehicle reduced by 5%,
or that required for the full type approval (EU
or the USA or Japan).

Pirelli gets OE fitment on latest Porsche 911
If someone has already posted this info, my bad.
"FRANKFURT, Germany (Sept. 15, 2011) — German car maker Porsche A.G. has selected Pirelli’s P Zero ultra-high-performance (UHP) tire as an OE fitment on the latest iteration of its iconic 911 sports car.
Porsche will use specially developed versions of the P Zero on its 911 Carrera and Carerra Turbo models, according to Pirelli Tyre S.p.A. The new Carerra debuted at the Frankfurt Motor Show this week.
The new Carerra’s fitments are 245/35ZR20 front and 295/30ZR20 rear, with each being built with specific compounds, Pirelli said. The rear size uses an aramid-fiber overlay for improved thermal stress control, which helps deliver maximum lateral grip.
The P Zero tread features side blocks with optimized sipe depths to reduce noise emissions in compliance with European Union regulations.
The size fitments for the Carrera Turbo will be 245/35ZR20 on the front and 305/30ZR20 on the rear.
Pirelli said it has more than 200 OE fitment approvals for the P Zero."

It appeared that the cars in frankfurt had Michelins on them. Hmmm... this should be interesting as I have never been a fan of Pirelli high performance tires. There must have been a delay with Michelin getting the tires to market in time.
