Rimac makes components for all kinds of EVs, including small sustainable ones. Their supercars are basically a research platform. It's where they push everything to the limit, which helps them learn how to squeeze out every bit of effiency from their technology. Efficiency is just as important to supercars as to small sustaniable city cars so much of what they learn is directly applicable.

It's also a marketing stunt to sell their technology to other automakers.

I think they perfectly understand the point of electrification.
