I understand the increased performance in terms of the specifications (faster 0-60; higher top-end speed), and I understand that the PUP comes with different wheels, different brakes, lowered suspension, and a little spoiler (and probably other little things I'm forgetting).
However, I couldn't find any information on how the LR is different from the PUP from a mechanical perspective. How does the powertrain produce better performance? The HV batteries are the same, correct? So does it have a different drive unit? Or is it similar to the Model S Ludicrous upgrade where they replaced/upgraded a fuse? Or is it tuned by the ECU to go faster? Or is it simply a $10k software option and the powertrains are the same?
I'm mainly just curious. My google search yielded many results that talked about specs, but no details about the powertrain differences, if any.
