It looks like a new BMW 7 Series is in the works… And an all-electric i7 is on the way, too! How do we know this? Well, for starters, we’ve got our hands on some spy shots that show a petrol-powered 7 Series while it’s being tested. Not only that, but BMW has even released official footage of a prototype i7 in testing, so you can bet that’s not too far off, either! That’s not all though - we have our suspicions that either an M7 or i7M could also be in the works! But which will it be? Well given
