I heard about this a while ago, Cayman Platform might lead the way into a Porsche Motorsport electric GT4 series ?
where they will most likely, want to hold on to petrol / synthetic fuel for it's 911 platform and Motorsport models as long as possible.
just out: Article from 000 magazine:
First pics and thoughts from @dickiemeaden’s first drive in the 718 GT4 ePerformance offer a glimpse into customer motorsport circa 2026/2027: “It’s monster quick in that giddy EV way, but with far more finesse to thebraking and some tricks in the way it rotates into slow- and medium-speed corners. Race mode offers 600+hpfor 30-40min with no degradation in performance while Quali gives 1,073hp for 15min. The 718 GT4 eP weighs3,306 lbs vs a 500-hp 718 GT4 RS Clubsport's 2,866, but it can put down more than twice the power. OnValencia's start-finish straight, Race mode is good for 160 mph while Quali nets 172 mph. You get used to Racemode pretty quickly, Quali is wild. Lap times are faster than a 992 GT3 Cup’s at some circuits, while 0-62 comesup in 2.5sec on the way to a 186-mph top end. The 900V system can go from 5% charged to 80% in 15 minutes,and the 718 GT4 eP leaves pit lane at 85% charge so there's room for regen—and Porsche Motorsport believeshalf of the power used in a 30-40min race will come from regen.” More to come in Issue 023… Photos @gus.gregory
I can't wait for the first crashes that rupture the batteries and cause the track to be shut down for hours or the day. Not to mention where is the charging infrastructure going to materialize at....
The Tesla S has a battery capacity of 103,000 Watt Hours. (kWh). I am assuming a similar size for this car. I assume that the voltage will be 800 Volts, the higher voltage that VW and Porsche are using. I think the video said that 85% of the energy will be recovered in braking etc. So you charge it up, 0% to 100% at 800 Volts in 8 hours ish will take a 16 Amp 800 Volt source, not including battery energy retention and conversion efficiency and a bunch of other stuff I know nothing about......and don't plan to research.
That sounds reasonable. That will be a (800/220)*16= 58 Amps out of your 220V AC domestic source. Basically a 100 Amp breaker deal. Also that does NOT include the conversion efficiency of taking 220 VAC stepping it up to over 800 VAC and rectifying it to make 800 VDC. There are high frequency
AC to DC power supplies, but I bet the highest efficiency is in the 85% range (a guess) so yeah it will be 100 Amp breaker deal at 220 VAC.
Go out on the track and drive, and let's say you drain the "tank" 50%. Now you need to shove 51,500 Watt Hours of energy into the battery at 800 V. If you want to do that in 30 minutes, you'll need a 128 Amp 800 Volt source. Pretty sure you'll need a 100,000 Watt diesel Caterpillar generator. Yupp it's an EV.
Meanwhile 1 gallon of gas is 33,400 Watt Hours , so that 30 minute session in my 718 GT4 CS uses about 8 gallons of gas or 267,200 Watt hours of energy. Twice the battery energy of a Tesla S, so the EV is definitely more efficient......but the "petrol" version "recharges" in a few minutes.......and the energy storage volume is 2 five gallon cans.

the cleaning lady told me that all boxster and cayman go electric in 2025.
the 2025 cayman race car will also go electric and be used in single make series or E racing along side of other electric cars.
2025 GT4 cars will be 911 carrera which you will see in SRO and IMSA still burning gas.
Enjoy your Cayman clubsports folks and hold on to them as long as you can. They might not make anymore next year.
Interesting that 2025 GT4s will be 911s, had not heard that. Wonder what engine they will use. A couple of friends recently bought new 992 Carreras and are stripping and building cages in them to race with PCA. they have been going around with PCA Club racing on classing.

New GT4 is intriguing. How are your friends installing the cages in the 992? As far as I can tell the Cup car shell has different sheetmetal so the steel cage can attach to the aluminum shell and properly spread the load.
