The prices in US will for shure be lower but I think the Taycan Turbo S will be 10-20% more expansive than Panamera Turbo S. I heard that the Taycan Turbo S will have over 1000hk and 0-100kph under 3 sek.
The Taycan 4S will be round 100,000 euro and the normal Taycan even cheaper..
The Taycan will for sure weight in around 2.5 tons so air suspension it must have..
I think it will be nerly 5 meters long and 2 meters wide, the height will be as many has written before 1.38m
