Tesla, Inc. announced that the cheapest versions of its Model S and Model X electric cars will only be offered until January 13, 2019. After that, customer need to pay for the 100D models or opt for a cheaper Model 3 instead. Tesla Model S or Model X electric cars with a 75kWh battery. On January 14, 2019, the cheapest version of both models will be the much more expensive 100D. The company confirmed that dropping the smaller battery was a move towards adopting the Model 3 way of representing vehicles with mid range, long range, and performance versions. So it seems likely the use of 100D and P100D to denote versions will disappear next. By discontinuing the 75kWh battery, the price of both models increases considerably, for example, the 75D Model S costs $66,250, but when it disappears next week the cheapest Model S will be the $84,250 100D. The same is true of the Model X, with the 75D version costing $72,450. Next week, the cheapest Model X will cost $87,450. Model 3 pricing ranges from $33,950 for the rear-wheel drive version up to $51,950 for the dual motor all-wheel drive version, so there's already a very clear pricing gap to the Model S and Model X.
