    Dual Motor Performance - Single On-Board Charger?

    Hello All, My family recently took delivery of a fully-loaded Dual Motor Performance Ludicrous mode X and was amazed to learn that it only came with the standard 48A on-board charger. This was not listed anywhere on the website and there is no factory option to "upgrade" to the dual 72A...
