The downside for Porsche is additional official curb weight if they were to make the larger tank standard...

Question is why are there two tanks. TCS may explain.

I don't think RHD models can accommodate the 90L tank. Since both tanks are in production, Porsche decided to allow a choice. Everybody wants choices, right?

Sorry if this has already been discussed, but what's the range for both tanks?

I'm guessing about 1/2 of a track day or 40 laps for the small version and 60 laps for the larger.

60L lasted about 45 minutes on track with 4.0 maybe 50 minutes with 3.8L, or just not 2 sessions it was a PIA.

90L should last 70-75 minutes, plenty for 2 sessions, good enough.

Maybe that's why they added bigger PFC brakes?
And maybe it speaks of confidence in keeping the engine and transmission temps under control?
A DE car only needs to stay within operating temps for as long as a tank of gas lasts right ;-)

http://en.wikipedia.org/wiki/Curb_weight
Curb weight (US English) or kerb weight (UK English) is the total weight of a vehicle with standard equipment, all necessary operating consumables (e.g., motor oil and coolant), a full tank of fuel, while not loaded with either passengers or cargo.

The "Standard" GT3 Tank holds 16.9 Gallons. The "Optional" 90 Liter Tank holds 23.7 Gallons. If standard, the extra 6.8 Gallons would increase the Curb Weight by 41 Lbs, From 3,153 to 3,194 Lbs. Lighter Curb Weights are desirable for marketing purposes and result in lower taxation rates. In the real world, almost all cars actually weigh more than their "official curb weights".

Almost 24 gallons is bigger than some SUV tanks! Is there any storage area in front lost to this bigger tank?

See Post #2 of this thread. It appears not.
