@Kithmo - That is a good question ??

.
It is very difficult to tell what is going on here ?.
I think we can completely rule out steel wheels, because you can see the brake callipers through the road wheels ?.
Is it like some Tesla models, where the car has alloys wheels fitted, but then they slap on a wheel covers over the top ?.
I have tried hard to study the images of the wheels on the face lift model, but I am unable to see any visible provision for road wheel bolts ?.
Some manufactures who use a nice alloy wheel, then use a fancy cover that will over lay over the centre of the rim to hide the road wheel bolts.
But again, I can not see any evidence of this type of arrangement on the face lift ?.
The diamond cut alloys on the original ZS EV are a nice but are an expensive feature.
Maybe MG have gone for a more cost effective option of using a basic alloy wheel, then added a shiny cover mounted over the top, to give a similar effect ?.
Little bit of cost cutting to hopefully hit the right price point.
The biggest increase in price will be as a direct result of including that larger 72 kWh pack on the Trophy ? model.
It does satisfy the criticism of certain people who said the range was a little too small on the original car.
And it would also appeal to first Gen owners who would like to upgrade to the bigger pack.
Offering it in two sizes, is a good move and covers both camps I guess.
When the car was first released, it’s closest competition was the e.Nero and the Kona, but the price of both of these models where a lot more expensive.
The biggest pull, was the 64 kWh packs.
So MG have responded with the 72 kWh pack on the face lift now.
If the 72 kWh model proves to expensive for some people, then they have the facility to increase production on the smaller pack model, without too much bother I guess ?.
