Visionary projects

Bold cars by small makers and start-ups – prototypes, show cars and ventures that aimed high. Some are still in development; many never reached series production. Every claim is sourced; announced figures are shown as announced, never as built.

“Built” shows the figure with the strongest evidence for what each entry counts – the whole model, or only the rare specification. Rarity labels are editorial; the exact numbers and their sources are on each page.
