It is apparent just from touching the thermoplastic exterior of the i3 that it is a new beast in the industry. I did watch the video where BMW beat up a thermoplastic panel from the i3 with a hammer, and it seems that this could be a great improvement in the fragility of commonplace vehicles with a steel chassis.
During real-world usage, does the thermoplastic exterior resist scratches and scuffs? Although this was designed to make scuffing or impact at under 2.5mph practically a non-issue, I am confident that even if the vehicle were keyed it would be significantly worse than it would if any other BMW were given the same abuse.
BMW has a great opportunity here and is onto something. Scratch-proofing our vehicles is one of the steps to building a perfect vehicle, along with electric driving and autonomy.
