The Squad, a new urban car from an Amsterdam-based startup, is barely bigger than a bicycle: Parked sideways, up to four of the vehicles can fit in a standard parking spot. The electric two-seater's tiny size is one reason that it doesn't use much energy--and in a typical day of city driving, it can run entirely on power from a solar panel on its own roof. A swappable battery provides extra power when needed.

The car is slated to begin production in late 2022, and will be priced at around $6,800.
