If you’ve been longing for a hot electric hatchback from Volkswagen, your wait is nearly over. The first electric car to get a GTI badge won’t be the Golf, but it also probably won’t leave you disappointed. It will be the Volkswagen ID Polo GTI EV, previewed by last year’s ID GTI concept car, and it will be a 223-horsepower supermini with the fun to drive you expect from a GTI. In theory, anyway.
