Wrong! My info is based on Porsche’s statements.
Porsche: “The service life of the lithium iron phosphate battery is 2.5 times that of a conventional lead-acid battery, but it only weighs approximately a third as much, at 12.75 kilograms.” LINK
Also from Porsche: “Thanks to the advanced battery technology and power density, 20 per cent less space is needed and the weight of the on-board battery is reduced by more than half, from 60 pounds to 28 pounds. These features made it possible to reduce the 95 Ah capacity of a conventional lead-acid battery to 60 Ah for the LiFePO4 battery.”

The lightweight lithium-ion battery is 12.75 kg (per one Porsche statement) or 28 lb (per the other Porsche statement). That’s correct because 12.75 kg = 28.1 lb.
The regular battery is about 60 lb / 27 kg (per one Porsche statement).
So the lightweight battery saves at least 32 lb.
The RAS system by itself adds about 7-15 lbs from what I’ve read online (can’t find a definitive source). If that’s right, adding RAS as an option saves an overall 17-25 lbs.

For sure. The RAS is awesome because of the added stability and improvement in driving experience. I’m just saying that it also adds a better/lighter battery system and actually makes the car slightly lighter (in case someone might thing adding RAS would make the car heavier like some other options do). But totally with you that 50 lbs here or there isn’t gonna make any difference particularly if used on the street.

I’m super excited about the extended range tank.
A guy a work asked me about my incoming car last week.
“What kind of car do you have coming in?”
”911 GTS Cab.”
“Nice. I just got a C8. How much horsepower does it have?”
”I don’t know…but let me tell you about the gas tank!”

*I think it's debatable whether the upgraded battery is "better" - for sure, its performance is better (supposedly the RAS requires its higher performance) when it's working (i.e., not turning the car into a brick). There are so many reports of issues w/these batteries. My incoming Carrera T has it (despite no RAS - this battery is standard on the T so the RAS option def adds weight on a T!) so I sure hope it doesn't cause any trouble.

I've heard the electronic actuators for the RAS allegedly weigh around 14-16 lbs each, which [when added together] would more or less fully negate the weight savings of the upgraded battery* but, like you, I have not seen a definitive source for those figures therefore it's just speculation. So we can't say for certain that the RAS option saves any weight. Regardless, if there is in fact any weight difference at all, it's a trivial amount whether it's a few lbs less or a few lbs more - a difference I wouldn't even feel in my 2300 lb Miata, let alone a 911 weighing roughly a half ton more.

I wouldn’t worry about the reliability. Porsche claims it lasts 2.5x longer than the regular battery plus you’ll be under warranty.

thanks! its not AWD so i'm definitely getting the extended fuel tank
currently its a chalk on black leather; but debating if i want to go full GTS interior.... Debating between the 18 vs 4 way seats. I had the 14 way seats in my 991.2 and definitely want the sport plus seats this time around.
also debating the premium pack. only thing i care for is folding mirrors and Bose..
too many choices lol

I had 14-way on my Panamera and was worried 4-way wouldn’t give me enough adjustability so I opted for the 18-way. No regrets!
Add the premium package!
Chalk is a fantastic color and I’ve loved it on my Panamera. Beautiful, changes character in different lighting, and relatively easy to keep clean with ceramic coating. You gotta get the black accents though otherwise it may look boring.

I don’t think there can be any question that the whole RAS system makes the car lighter or else Porsche wouldn’t add RAS to the lightweight package (at least that’s the configuration on the GTS Configurator). They could’ve simply added the lightweight battery and skip the RAS from the lightweight package.
I wouldn’t worry about the reliability. Porsche claims it lasts 2.5x longer than the regular battery plus you’ll be under warranty.

I wish I could not worry about the reliability of the lithium battery but there are just way too many reports of 911s having trouble with it. As for the warranty, there are also numerous reports of Porsche trying to void the lithium battery warranty, so that is of little comfort.

P.S. Congratulations, OP!
