Tesla current beats them on almost all marks:
310 Mile range: This is using the UK cycle which is commonly compared to EPA cycle(which is lower). Using UK to UK you get:
- ~320mi range P90D / P90DL
- 350mi range 90D
3.5s 0-60: - P90DL: 2.8s
- P85D/90D: 3.2s
Price: Rumors are in the ~200k range which again Tesla can beat(you can get an 85D for half that with better range and 0-60 which is close).As for the 15min charging. We haven't seen it in production at all. Also the fact that they're going with 800 VDC pack means there's a good chance it won't work with any other DCFC standard(CHAdeMO, SAE Combo, SuperCharger) without a step-up transformer so you'll be limited to only Porsche's chargers.
Also you can buy a Tesla today, not years down the line.
I really don't understand where all this "Porsche is going to beat Tesla" press comes from, it's like Apple claiming they were the first company to support Open Source, there's nothing to back it up.
