BMW is preparing an all-electric full-size sedan to compete with the Mercedes EQS. Its expected to be the i7 but so far media outlets are having a hard time confirming that. I don't really see what else it could be. Definitely not an i5.
The I7 is beautiful. I found thus on a thread in thus forum. The "executive/engineer" level briefis are very boring, but the I7 is shown in all its glory about 15 minutes or so into the 2hr webcast.
