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?
In: Engineering
Generally the larger an engine is (displacement measured in volume) the lower the exhaust tone and the lower the rotational speed limit. The opposite is true as well. The faster an engine rotates, the more frequent the exhaust pulses which makes them seem higher in pitch.
The engine in the Viper is almost twice the displacement of the Lexus: 8.4L vs 4.8. The Viper’s engine has a redline of 6200 RPM and the LFA is 9000RPM.
