Thats how you get this weight.
And you probably can't even make all of that as lightweight as you could, because you want to go for some driving dynamics. You need to preserve the weight balance of the car, so you need to put some heavy components in the front where gas engine used to sit.
And how to reduce it? First rework the chassis, design and materials. Then the battery. Then make everything lighter, all the components, wire harnessses and everything.
Reusing existing chassis and components makes this difficult.

Exactly! The others started as an electric platform with a skateboard chassis and the batteries are an integral part of the structure. The I4 probably reuse the 4 series chassis.
