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

2.09K 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?

Here is an amazing video explaining everything about car sounds, dont know if it will let me post a link, there was another video i think from Engineering Explained that he did a while ago that explains just the part of why V8 american muscle cars sound different than V8 european cars but i cannot find that video.

TLDR is:

American V engines normally have a cross—plane crankshaft, which results in their distinctive rumble at low revs, whereas European V engines normally have a flat-plane crankshaft, which results in a less distinctive low rev sound but a distinctive high rev scream.
