@Olle Simplification and cost reduction sure make sense especially for all things Tesla these days. However, the same motors from the M3 in a heavier car wouldn't be able to achieve the same performance. I believe the 0-60 times for the M3P and MSLR are both 3.1 indicating that the MS must have more power right?
I did double check the website to see where the LR is specifically mentioned.
"Both Long Range and Plaid
powertrains, with
updated battery architecture, are capable of back-to-back, consistent 1/4 mile runs."
"New module and pack thermal architecture allows faster charging and gives you more power and endurance in all conditions"
So the LR will have a new battery architecture and a different powertrain than the Plaid but still not clear if it is just motor count or something more.
If you look at the Electric Powertrain section of the
Model S, the front motor graphic stays the same with only the rear powertrain changing when toggling between LR and Plaid. Hopeful thinking for sure
