By then S will have been a 10 year old design with only one minor facelift. Nobody will buy the Model S if Tesla does this.
It makes sense for Tesla to consolidate its packs around a single battery form factor, the 2170. When Tesla will bring them to the S/X is anyone's guess, but the Model S is ripe for a total redesign. It's looking very dated.
As someone who bought a MS P100D last September, I disagree. You have to look at the competition and the charging network. Every automaker is currently playing catch-up in terms of range, charging network, and performance.
When we bought the MS, we were looking at ICE cars, Panamera Turbo, Mercedes S class, Audi something
We didn’t want to wait for the Taycan and had questions about how Porsche will build out their charging network. Neither the car nor charging network exists now just like the Lucid air.
I think the model S will sell just fine in it’s current incarnation for at least 2 more yrs because the range, performance and Tesla’s charging network are head and shoulders above the competition - currently nonexistent. All the carmakers are aiming at Tesla’s 2018 range and performance. By 2020 when these cars are finally out then Tesla can increase the S/X range by 200 miles to 500+ miles.
After 300 range, incremental increases of 50, 60? miles don’t matter much as a selling point.
I am a complete noob and know nothing about the battery nor care to be completely honest. I care about range, charging speed and performance; for this I am waiting for the 2020 roadster.
My current S with its 315 range - I can drive for 3 hrs without stopping on road trips - and ludicrous mode and L+ - I can smoke a Lambo - are more than adequate for my needs.
