This is all based on the article stating that the vehicles will have 48v hybrid systems...I have no knowledge whether or nor this is true.
There are limitations to the amount of horsepower a 48v system can put out...it is not going to put out the 160 horsepower or so that the system in the Ferrari 296 does. For example even if the small battery can deliver 500 amps of current, the maximum output (assuming 100% mechanical efficiency) is 32 horsepower. The entire existence of 48V systems is for compliance reasons, they became popular because they cost under $500, and they cut CO2 emissions by 10-15%. Higher voltage systems are better for performance, 48V systems are used because they dont require special precautions when manufacturing or servicing the vehicle.

Inspired by the KERS technology used in F1, the software for the fast-charging 400-volt system was, we hear, co-developed by Porsche and Rimac. The T-HEV system fuses two electrical elements. According to a supplier, the integrated starter generator (ISG) creates an on-demand instant boost effect and drives the auxiliary equipment. The actual e-motor positioned under the fuel tank propels the front wheels and improves the weight distribution. The tiny battery which powers the compact electric drive unit is charged by the combustion engine and the brakes. For complexity reasons, a manual gearbox is not an option, sources say. The complete T-HEV module is claimed to weigh no more than 25kg.

I believe in it, but I would not use “big” to further emphasize it. Less is definitely more…

Again 55 lbs is considerable. ⬆️

but you're getting 84 hp and 129 foot lbs of torque from those 55 lbs -- which sounds like an incredible amount of performance for the system weight
From CD article:
"The heart of the T-HEV system is a small battery which powers the compact electric drive unit. It is constantly charged both by the combustion engine and the kinetic energy generated under braking. For complexity reasons, a manual gearbox is not an option, sources say. The complete T-HEV module is claimed to weigh no more than 55 pounds. The engine in question is apparently a modified twin-turbo 3.0-liter flat-six rated at 395 hp and 347 pound-feet of torque. Assuming the electric motor contributes about 84 hp and 129 pound-feet to the action, the combined output should be around 478 hp and 475 pound-feet of torque. Apparently there is also an even punchier 528-hp version in the works that would plug the gap between the beefed-up future 911 GTS and the next 911 Turbo. According to the Weissach grapevine, the top-of-the-line 800-plus-hp GT2 RS due in 2026 will also use a hybrid setup."

What will be interesting is the pricing. I could easily see a "basic" build costing $180-$190K, which less than a handful of years ago is what the MSRP on a GT3 Touring would cost. Meanwhile the GT3s will probably start in the 210s/220s. Inflation is a hell of a thing...

Everything has gotten ridiculous - a basic bottle of red wine at a restaurant this weekend was $46.

That article is such a convoluted mess. The way I read it is the KERS is a 400 volt system coming much later in the 992.2 lineup as mentioned at the beginning of the article. That would not have a manual but the first iterations would only be a 48 volt system different from the KERS system and therefore allow a manual option. 70% of GT3 orders in the US were manuals. I don't think Porsche will be so quick to oust such a large customer base.

Excited for the NA 3.6L GTS
Basically from C&D article:
Base Carrera - no change except more power
Carrera S - 3.0 turbo flat 6 with 48v battery
Carrera GTS - 3.6 N/A flat 6 with 48v battery
Carrera Hybrid model - 3.0 flat 6 and hybrid tech. This model will bridge power gap between S / GTS and Turbo models.
