How minicars will survive by electrifying and evolving

European car buyers still want minicars, for their ease of parking, low cost and fuel efficiency. But automakers say new emissions rules that require costly modifications are making them economically unfeasible.

So, how can the key entry-level segment be saved?

In some cases, automakers are offering electric versions of existing models. In others, they are blurring the line between minicars and models one size up. A few players, including some new entrants, believe that limited-range electric quadricycles are the answer.
