"The Mustang Mach-E is built on the Global Electrified 1 (GE1) platform which is a heavily reworked version of the C2 platform that is used on the fourth generation Focus and third generation Kuga/fourth generation Escape. " Wikipedia page on the Mach-E.
True. I said it wasn't "built on the Escape platform." But you didn't say that it was. You said it was "derived from" the Escape platform, which is true enough, and I misinterpreted you. It's a new platform which was "heavily reworked" from the Focus/Escape platform. I'm not sure what point you were making, though.
