As above, CCS DC Rapid charge support will be standard on all of the i3's of that age in the UK at least. BMW's terminology can be a little weird when it comes to EV's. Their 11kW AC cable is called a rapid charge cable (11kW AC is anything but rapid!) so you'll sometimes see oddities about if the car is capable of fast or rapid charging.
If you are getting a late 94Ah car then you shouldn't need to worry about it lacking either 3-Phase AC, or DC Rapid charges. Both will be standard, but the included AC cables (if included at all) may not necessarily support it.
