I see the rules on the car being raced (what sort of restrictor needs to run, what's the restriction on the transmission, etc, etc.) but didn't see anything on whether the race cars needs to be based on the production car and how close it has to be.. so that means there's no reason / need for the race car to be based on a production car now?

Seem pretty obvious....the DFI design has been on market for 3y, and 5+ (i'm assuming) in development. If it was a strong choice for racing (meaning better fuel economy, with performance and durability), they would be running it right now.

WTF. Huge mistake to put it into the new road cars if it's not ready. Next year's cup cars had damn well better have the new motor.

Porsche is making an unbelievable mistake by using the older Mezger engine in the race cars and putting the 9A1 DFI engine in the street GT3 cars. Porsche needs to pick a engine and use the same one in the GT3 race and street cars.
PAG doesn't give a rats *** about YOU or me or the rest of the nut here. they can put a lawnmower engine in there and the Far East mkt will eat it up. the young and foolish facebookers will drive them home. i just need a good internet interface, heads up texting on windshield and fast connection to google, ebay, CL, yelp.... engine is not very important.

That.

The clutch is an essential part of sequentials and is used to start the car from a stop and also for downshifting.

For cups, the appearance of throttle-blippers in the 10/11 season has automated the whole downshift sequence but the clutch will always remain the fourth control surface in a racecar.

FIFY. And I could have added the word: "yet". The leap you've made to a bit too far. How good the DFI motor is, or is not, remains to be seen. Time will tell and Porsche is notoriously guarded on such matters - note the "grimace" re the fact that there were even pics, lol.

Agree fully.

If the info is true that there will be a 'road car' motor and a 'racing' motor, I think it can be fairly concluded that Porsche is also sending a clear message that 'while yes we tacitly acknowledge the track use of our road cars, they are not track cars and we expect such use to be "occasional" '.. Hence a timing out on hubs, etc. I would bet that Porsche would see the track use we here give these cars as 'excessive' and 'unanticipated'. In fact, they would say 'we have a great car for your use: the Cup ', lol...

If that 'bit of thinking' is accurate, it is pretty easy to see how Porsche will have reached its decision on the motors. And it would serve them well: They make more $ by simplifying production and adjust expectations relating to the GT3 line at the same time... No one can accuse Porsche of being dull witted..

Regardless of which engine they put in the GT3 or GT3 RS, they cannot switch to a 9A1 motor in the cup car in a year or two. If they launch the cup with the Mezger, it will stay a Mezger for at least two and more likely three years. This is due to he fact that current 997 Platinum cars need a racing home among 991s post production (creating a 9A1 car would essentially create yet another class making it 3) a 991 motor in a year is completely impractical

continuing.....a 9A1 motor is impractical because teams are then supporting two 991 based cars and one 997 based car....and most importantly the Mezger motor is a proven weapon and the 9A1 motor is built for volume production with cost as a key consideration. My bet is the RS cars stay Mezger (if not, my 4.0 license plate will say "legend" very soon) and everything else is built for housewives in Beverly Hills who think Mezger is an emerging handbag designer.

Couple more photos.

Uprated roll cage around the A-pillar and door cross-bars carried through to rear shock tower. Nice to see the front wheel spokes back to concave vs convex.
