I’ve done a great deal of research on this. My prediction. SR+ is actually MR(62kwh) software limited to 240 and only available for a limited time to drive sales in Q1. Here’s why
Tesla Model 3 - Wikipedia
- 240 exact without EPA est. Tesla knows the car will have at least 240 miles of range If it’s actually a 62kwh battery
- Timeframe. Plus is within 2weeks. Aka already being made. SR is 6-8 weeks, the time frame of getting 50kwh Standard range packs.
- Weight difference from SR+ and MR(now removed) is about 50lbs. Difference of Subwoofer and amp
- At ~ $150kwh for batteries, cost difference to Tesla in giving 62kwh as 50kwh base about $1800
- Top speed of SR+ and MR both at 140MPH. 0-60 is 5.3 vs 5.2.
