I found this in an article from AutoEvolution:
The trunk space is a big downsize for the ET7. For a car that is over five meters long (196 inches), the luggage compartment is too small, with only 364 liters (12.9 cu-ft) of space. However, the space for the passengers in the back is massive, so it's more understandable.
I know that's not the dimensions you were asking for, but maybe it helps!
