Euro 2 classification but where and by whom???

It’s like being bewitched: For days I’ve been spending on countless web pages just to get the question answered whether my pontiac transam gta with 5.7 liters and 181 kw or just 250 ps in a better pollution class, but so far there have only been cancellations! also in this forum I studied a whiny and didn’t get any further. maybe someone just guessed now? someone has the same car with the same ps number as me (most gta in this forum are weirdly not so strongly motorized from the factory…) and is already in euro 2? around an answer I would be very happy!
