I have the MG5 Facelift. I can confirm it comes with a 11 KW (max) AC charger but you will need a 3 phase cable to get this speed.
I know this as I had a single phase cable which capped out at 7. Now I have a 3 phase and get ~11KW
Brilliant! I started this tread because MG were showing a 7kW charger for the upgrade model.
I bought the MG5 in April 2022 with a plan to exchange it later for the upgrade model.
It's great news MG have stayed with the 11kW charger.
I brought in 3-phase last summer and a 22kW Zappi. The existing single phase CU (the whole house) is fed from the new 3-phase CU. I kept the previous 7kW charger (in case 2 EVs or if the Zappi fails). I confirm the 22kW Zappi will work (at 7.2kW/hour) with the 2022 MG5. There was a bit of kerfuffle coordinating disconnection of the single phase and removal of single phase smart meter with the new 3-phase connection/smart meter (needs all to be choreographed in one day).
I paid £1500 to bring in 3-phase (after a bit of haggling). I did the trenching and conduit myself.
22kW Zappi and new 3-phase CU with feed to existing CU cost another £1600.
Half the reason to bring in 3 phase was to facilitate DNO approval of a PV extension (DNO export limit can increase x 3). Its also a piece of infrastructure that future-proofs the property for 2 EVs and higher power charging/importing.
