Add 10 gallons of gas to an ICE Hummer and 10 gallons to a Honda Civic is also vastly different. No one talks about adding miles of Gas, because you don't buy miles, you buy gallons.I get your thinking, I just personally think it's actually less practical (just the way by brain works, no disrespect intended). Add 50kWh to a Hummer EV and add 50 kWh to an AGT...they mean totally different things in the real world. Yes, you can do the math yourself in your head, but how valuable is saying "I can add 50 kWh to my battery the fastest?" It's utterly useless if the car is inefficient and poorly designed. So probably some combination of the metrics of speed to charge -- based on kWh, NOT SOC and efficiency would be best.
For an EV you buy kWhs. Most gas tanks don't show you number of gallons left is 1/2 tank.... so state of charge is very similar to principles people already understand.
With my driving I know I will get 3.5 miles for every 1 percent of charge. Making the math easy.
Coincidentally, I have a 2025 Sierra EV that gets 3.5 miles to 1 percent of charge. Of course each percent is 1.18kWh in the Air and 2.05kWh in the Sierra.
GM has done a very good job on the charging curve for the Sierra. Not sure how they are managing the dual pack, seems they are taking one pack very low. Even at 30% SOC I have pulled 350kW. 358kW from an EA charger if you can believe it and 150kW from 400V Tesla station.
On road trips I tend to start from home with 100 and then charge from 30-80. The Air is 20-30 minutes and the Sierra is 30-40 minutes.
Example for the Sierra 99kWh in 34 minutes. 32%-80%. 175 miles, but that's specific to my driving and my vehicle.
Wether it is an ICE or EV I know how far I can go on half a "tank", I know in my ICE truck I'm going to buy more gallons than in Corvette, and I'm going to buy more kWh in EV truck than the Air.
