Cars - Alfa Romeo 155 Q4 & Abarth 595 SS - Wrong engine sound

I haven’t seen anyone else mention it but both the Alfa 155 and Abarth 595 use incorrect soundfiles for their engines. The Alfa instead of using the exact same soundfile as the Integrale Evo, as it should since they share the same engine in an almost similar state of tune and if you look them up they sound very similar, uses the same engine noise as the Porsche 944/968. As for the Abarth, for some reason, it shares the same soundfile as the Jaguar inline six? If they didn’t want to record the sound of the car couldn’t they have used a soundfile of another twin-cylinder car like a Morgan 3-wheeler as to sound a little more accurate at least?
