Who's going to buy a model S75D at $75k when they can get a P3LRD for $75k. Who cares, because Tesla margins will be double on the model 3 P variant vs the model S75D. At some point the S75D goes away. Probably when the S120D comes out with refresh interior. S will move up market, model 3 will fill in the 5 series and e-class level vehicles. And I predict a P120T with 2 second 0-60 to fill the gap between the S and roadster, basically being a P200T.
The impact on margins from this will be huge. The market for a Model S P100D is very small, but at an estimated $75k, the market for the Model 3PLRD will be approximately 10-100x larger. Its imply a matter of how many people can afford a $135-160k car vs a $75k car. In general, I see the model 3 competing with 3/4 and 5 series with the highest optioned up Model 3s able to compete with the 5 series as well as the P variant competing with the M5, which is a car that starts at $102k car, typically $115k.
M5 has passenger room of 98.8 cubic ft. Model 3 has 97 cubic ft. About a basket ball difference in interior space.
M5 has more trunk space but no Frunk. Advantage M5 for sure, but not by much due to the Frunk.
M5 has only 300 mile city range, but 420 highway.. blended is only a slightly better then the probably 320+ range from Model 3P
M5 is 4300lbs while the Model 3P will be under 4000lbs (3838lbs for the 3LR)
M5 is 2.8 0-60. I expect Model 3P to be very close to this with maybe a ludicrous update to 2.7 to beat the M5 but probably also bringing the price closer to $85k.
M5 is much bigger then the M3, which is almost identical in curb weight to the Model 3, so the Model 3 matches up even better with the M3.

Could probably the the same comparison to the S4 and AMG version of the E class. But why bother.
The impact on margins will also be very good. Consider this: Tesla will be swapping Model S 75D sales at $75k for very high margin Model 3PLRD Sales at $75k. The difference in margins could be huge. They save 20% in just raw materials due to size. Another $4,000+ in battery cost savings from a battery based on 2170 cells that are locally sourced and not shipped from japan. Another roughly $12k savings from the raw materials and manual labor. So swapping S75D sales for the Model 3P would net $16,000 more per car gross margins. No one will want an S75D, but that is ok because Tesla is going to be going from <15% GM from a sale to >40% from the Model 3PLRD. The impact on margins could be more then measurable. If Tesla sells about 10% base model S75D, with no meaningful options, which would bring down Model S GMs by 2-3% given 10% of 30%. Replacing this with even just 30% GM Model 3Ps would increase the total margins by 3%. In effect you are taking away a negative 3% and replacing it with a positive 3% so the swing is conservatively 5%. How is Tesla going to get from 17% blended automotive GM to 25%+, this is one step. The other is clearly maximizing the Capex investment to better amortize the total Capex and Opex across more vehicles produced, but that is boring stuff. Performance Model 3s are fun!.
