This is a great discussion. It has gone slightly off the rails from the title description but into more interesting territory.
So will the Model III have more performance chops than the Model S? Some are saying yes, and some are saying no. How about both?
I expect the base model to be slower than the 60 kWh Model S. Say 6 to 6.5 seconds 0-60 MPH. I would still hope for decent EV chops at the 40-60 MPH range and it will still blow away any ICE out there.
I hope and expect there to be more choices with a car that needs to appeal to 500K worldwide customers. A base model with 6 to 6.5 seconds, larger pack/better performance version 5 to 5.5 seconds, and official Performance version with 4 to 4.5 seconds which would fit with the Model S in possibilities. There might even be room for a Super Sport version with a 3.5 to 4 second 0-60.
I truly expect there to be a Model S 2.0 to come within a year of the Model III with the newer batteries for both increased performance and range. The car will be due for a refresh right about that time or possibly before the Model III hits production. I'd think that Tesla would want the Model III batteries thoroughly tested before they reach full production on the Model III in cars.
I can't imagine the base range being above 200. I'll expect an EPA of 180 to 200 for the car. Just because of cost I can't expect any more out of Tesla for the base model. I like the pricing and of course options will add to those numbers. The larger pack should add an extra 80 to 100 miles to the range.
I do agree that the Model S 2.0 will be there within a year of Model III. New model year takes place about 5-6 years in the auto industry. I believe MS 2.0 will be more luxurious with more options (better seats, better interior, etc.). If Tesla follows the BMW strategy in performance, the Model III will be just as fast 0-60-wise as MS. Model III may be even faster due to lighter weight. This is proven to be true by BMW that with the same engine used in 3-series it performs better than the 5 and 7-series.
