@Pilou:But not habitability for old people : height is like 2 wheels
...indeed !! :)
Definition of -GT- from the FIA (1961)
" Grand Touring cars are vehicles built in small series for customers who are looking for a better performance and/or a maximum comfort and are not particularly concerned about economy "
...maximum comfort ;)
It's hard for me reading the term "GT" on a futuristic concept supercar,i think it belong to the past
Alfa did the GTA (Gran Turismo Alleggerita=lighten)

and also the GTAm (Gran Turismo Alleggerita modificata=modifyed)

Maserati, did the first GTI with the 3500

Alfa again did the GTV(Gran Turismo Veloce=fast)

talking about -CARS- we must talk Italian :)
so Nikola,choose wich kind of -GT-belong your car...i think -GTAm-
