I hope they succeed, but probably will fail with too complex design. Original 2cv is wonderfully simple. If they can keep that simplicity, they will win.
In general, an EV powertrain is far simpler than the equivalent Internal Combustion Engine vehicle. Like only 10% of the number of moving parts. Or fewer.
So it depends if you're comparing this vehicle against its ICE predecessor (far simpler!), or against other EVs now on the market for around 20K euros (not yet known).
