How much can be reverse engineered from sound ?

That's more flexible and makes it a lot easier to pass regulations. Some cars even allow you to set different profiles and have a differently sound of choice.

I am surprised they also did not use the active suspension to tilt the car when the engine is revved.

0-60 in just over 0.5 seconds

after 3 seconds, 240 mph

I never found those sort of purpose built drag vehicles to be all that interesting though really, I mean they're completely useless for anything other than a very brief drag run. A car or boat that you can actually use is a lot more interesting.

Not engine sound, but all this talk of sweet sounds makes me think of the Hawker Hunter Blue Note, skip to 15 seconds.

If you are referring to the OP question, it is probably relating to what you can infer from the design of something by the sound it produces.

A long time ago in a far away galaxy, I worked for a lab that performed sound measurements in cars. The goal was to provide acoustic comfort for the driver and passengers.

The measurements were taken in a controlled environment and objectively analyzed so that the engineers could pinpoint the exact sources of noise and try to mitigate it.

It was not exactly reverse engineering, but it was a puzzle that had sound as a starting point.
