Who they are

A short write-up on each car, one paragraph apiece. We describe them on their own terms rather than picking a winner.

Profile · Electric 65 (facelift 2024)

Dacia Spring

Budget EV in the A-segment. Small 26.8 kWh pack, WLTP around 225 km (manufacturer figure, indicative), substantially less in winter and on the motorway (public forums, not measured by us). DC charging limited to about 30 kW, power 65 hp. Deliberately a city car, not a long-distance machine.
