Definition of hatch then yes, for hot hatch then equals sport which equals 3 doors
Not sure what planet that definition comes from! Being pedantic, it's a hot hatch if it's fast, good looking, handles well, and is as usable on the sporty windy roads as it is taking the kids to school and doing the weekly family shop. A hot hatch is something practical that is "all things to all men", and for that, a 5 door GTI takes some beating.
