For a second I thought you are referring to 'premium family' as some kind of a social category.
Mercedes, BMW are targeting the premium middle class market especially with the new A and 1 series respectively.
A C-class with options will run you $50k now, and $65k on an E which has long been their bread and butter car.
I'm less familiar w/ the BMW family but I'm sure it's similar.
So I think Tesla is absolutely competing with Mercedes and BMW, though certainly their most high-end models are competing with world class cars of any nameplate.
I have zero doubt the parking lots next to the ski slopes will be covered in Model X's in a couple of years.
Gull-wing doors seem less than perfect for transporting ski gear.
I was going to cite this article as a source, but I see that there aren't any numbers: https://www.google.com/search?q=mr+money+mustache+road+tripp...
Linked anyway for your interest.
The Model S is one of the most popular cars in Norway, so their cold weather capabilities are clearly pretty decent.
That said, the P90D is faster at 0-60 (with Ludicrous mode) than the Cayenne Turbo S. So there is that.
When do you go faster than 100 mph?
Yes, a rolling start is a big help on highway ramps. Doesn't help much at stop signs and lights.
By and large it is more efficient to accelerate at full power, assuming your goal is to reach a certain top speed regardless, so if you were _really_ concerned about conserving petrol then you should be going full blast off the line. That said I expect the fuel usage such a situation to be negligible anyway, especially to someone who can afford/justify a car that does it in 4 seconds.
My car isn't that fast, or particularly economical, but I know I've never thought "I'd love to accelerate at full power here to show how fast my car is, but I just can't justify the pennies it will cost me"! Outside of hyper-milers I wonder how many people do actually think about it.
Cayenne Turbo S (the fastest Cayenne model) does 0-60 in 3.8 seconds. [1] The Model X P90D also does it in 3.8 seconds, or 3.2 with the speed upgrade, which costs $10k on other Tesla models, [2] bringing the total Model X price to $152k to the Porsche's $157k.

Also (a) the Model X will ship as standard with 6 seats and (b) the X5 has a 7 seat option.
Obviously their next car will be the one that is accessibly priced and sells in huge volume.
