How many BHP does it take for you to consider a car "powerful"?

Power ratio is all that matters : 400 BHP/ton

I’d say from 250 to 300 is definitely powerful

For me it is 175+

I’d say, it depends on the mass…if its an SUV or a small hatch, all rounder would pin it to ~280-350 WHP.

400-650hp

200bhp and less than 1400kg

depends on the car you’re talking about?

good engine = 250 bhp
powerfull engine = 300 bhp

400

Depends how it feels when you drive it…
