How does this differ from the other AMG GT entries?
Our history records the model under several designations. Each group covers different units, so it is worth checking all of them.
How much does the 4.0 twin-turbo take?
It is a twin-turbo V8 with substantial headroom, even from a high factory output. Stage 1 works with standard hardware.
Is pop and bang legal?
It is not permitted for road use in Spain: it alters the exhaust's approved behaviour. It exists for track and closed-circuit applications.
