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

1.15K 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?

Well, to really grossly oversimplify it, you can think of it like people. Most people have two lungs, but very different voices. We all have different length windpipes, different shaped mouths, different vocal chords. It’s the same with a car. Lots of things are different besides number of cylinders. Lexus famously worked with Yamaha, an instrument maker (yes they do more than that), to tune their exhausts for a certain effect!
