The focus of this thread is the Tesla's model range to be expected in 2020, taking rather market than technology aspects into consideration.
What I expect in 2020 is:
Model S: 85kWh (85k€), 135kWh (105k€) + luxury package: 5k€
Model X: 85kWh (85k€), 135kWh (105k€) + luxury package: 5k€
Model G3: 60kWh (45k€), 85kWh (55k€) + luxury package: 5k€
will be a down-sized S (optimized 60kWh battery, sub-S performance, focus on price)
85kWh is the S-battery
no longer a 60kWh version
lower production cost, improvement in battery, overall "evolutionary" improvement
135kWh: new battery generation (that's why 20k€ is assumed)
same (overall) performance as Model S
Tesla will NOT address the ICE-market, but the EV-market
Tesla will stay at an all-electric car company (no hybrids)
Tesla will position itself as "far superior" than other EVs (in its category) and reaching a "low-limit ICE-range): it will not really "compete" with an ICE in the same category, but provide an "acceptable" performance
Tesla will not enter the city-car market (Mitsubishi, eSmart, eVW etc.)
Given that, Tesla will "set the standards" in EVs - and that will be its USP.
