Why do some Sports/Supercar engines “whine” while others “growl”?

2.08K viewsEngineeringOther

A Dodge Viper and a Lexus LFA both use a V10 engine, but a Dodge Viper has a very “deep” sound, but a Lexus LFA has a very high pitched whining sound?

What makes a car like a muscle car like a Mustang or Viper have such a different sound than a car like a Lamborghini or Ferrari when they use the same kinds of engines?

Engine works by making lots of booms. Engine sound comes mainly from pattern of booms. Those two engines are shaped slightly differently and make booms in different patterns QED.

*Booms spaced evenly make a “smooth” higher pitched sound while uneven booms make a rougher, deeper tone. Think Ferrari V8 vs Mustang V8 for another example.
