It was probably a "compliance car" or something along those lines. Automakers have been building tiny batches of compliance cars for decades to fill a certain small niche. Usually to appease some government regulation or under threat of more strict rules. Years back Ford and Toyota (and others) built handfuls of electric early Focus and Rav4 to comply with Californian rules and there have been others throughout the years.
When you look at these early electric cars it really shows how far behind battery technology and motor design was. People love to come up with ridiculous conspiracies, but the fact remains that even in a small car 15 HP is atrocious and the range for that Peugeot was probably 50 miles, if that. And I'm sure Peugeot lost money on every one they sold. They were simply not viable 2ith the technology at the time.
