Aero covers make no difference at all the only use is to cover the 80s alloy. I changed my wheels after 2 months of ownership and no difference to economy at all. Stock wheels will go back on come winter.
I see the fitting of these basic alloys as a pure cost cutting measure on the ZS EV model at least.
The original Gen 1 ZS EV had diamond cut wheels, maybe the windmill design was not to everybody’s taste, but at least there were a diamond cut rim that looked half tidy.
Yes - They could have gone for steel rims with aero covers, but that would have added more weight, meaning less efficiency / range.
EV drivers are constantly searching for more range for less money spent ?.
So, we arrive at basic older style alloys, with a more modern design plastic cover to try and smarten up the appearance.
I think MG where fully aware that these basis alloys did not really do the car much justice in the appears department, or they would not have included the plastic covers at more expense, had they looked half decent.
Alloy wheel design is always going to be a personal choice, that’s why the third party manufacturers sell so many every year.
If you have the storage space and the budget, it is nice to have the facility to run summer and winter rims ( with winter tyres ) at your disposal.
I once owned a BMW that came equipped with steel rims.
I used these thorough the winter and then switched out to a set of nice looking alloys for the summer months.
