You know, the sound would be so much better if it was set to the interior all the time. Or at least if the option was available to set it that way. Many of these cars sound incredible inside then you go to outside and the sound loses most of its character. You really miss the low end from the V8s especially but even the turbo 4 cars have some rumble with the right exhaust.
For me, a large part of the enjoyment of a racing game is hearing the motor. I’ll drive around and switch cars just to enjoy the unique sounds between the V12, V10, V8, flat 6, turboed, and supercharged. The work the sound team did is getting largely lost when I’m driving the outside view to enjoy how my car looks and enjoy the scenery.
