Apologies if this has been discussed elsewhere (didn't easily find the answer in my search). Why do the 40/60/85 kwh packs also have different 0-60 times? I know the Performance version has a different inverter among other things. But doesn't the standard car have the same motor/inverter etc just diff energy capacities for batteries? Also, related question: why do the mileage estimates for range not scale linearly with energy capacity? Eg. If Tesla rated 40 kwh pack at 160 miles, why wouldn't an 85 kwh pack be rated at 340 miles (eg 85 x 160/40)? Why did Tesla rate it 300 miles?
