Some group did a study on the car construction and ruled that Tesla overbuilt design on their model S. For instance the inside of a fender well liner on a normal car might be 3-5 parts, but on a Tesla it's 15-20 parts.

It was 9 parts in the fender wheel well because Tesla is a new company trying to do things differently, while not having the experience to nail it perfect. The Model Y fixes so much of the things that made their initial models inefficient.
This video answers your question. Essentially, the Bolt is a Spark that is retrofitted with electric components. Trying to fit a square into a round hole just leads to poor packaging, which adds weight and inefficiency, while limiting potential cargo/storage capacity and probably performance.
