Hi Ionut,

gr.A and N are currently homologated cars
gr.X are free modified production cars with expired or not homologation meeting the security requirements of annex "J".
Cars with valid homologation are not allowed in Group 'X'. For Group 'X' introduces minimum weights.
Unfortunately I can not explain what it means Group Е. But there are cars as a group X, but with larger modifications.
