First of all, thanks to Quasado for being open minded, that ' s a positive message.
Here is my proposal around the name "desire" :
D-zire (D for Design)
Dezir (unfortunately a concept car name from Renault)
This name can be pronounced in every language.
I have to admit "Expressive" sounded good to me
My feeling is we should avoid words like "vector" which sound a bit too technical /80's… too old (even if I am still listening music from the underground 80's)
