Looks good. A pity they pulled the plug.

I saw one thing I did not like though. The battery pack is made out of 32 modules each containing 252 cells grouped in 6 banks of 42 parallel cells (but arranged in 10 rows) with top mounted contacts.
This is more or less comparable to the Tesla Model S and X setup, but there each cell has a lead that cats as a fuse. Should the cell fail or get severely out of balance with the other cells in its bank, then it will draw a big current that blows the lead, isolating the defective cell.
The Dyson cells appear to be hard-welded to the copper so no fuses there... A single failing cell could therefore kill the bank or maybe even get overheated and catch fire.

The battery will be problematic, and so would setting up the whole production facility; new design, no car manufacturing experience.
It is a prototype though and the pack is designed to be adaptable to different cells; Dyson could just get batteries elsewhere.
I'd love to see Dyson strike a deal with Tesla for their packs and production technology to build that car for real.
