A method includes providing a fundamental frequency corresponding to the RPM of an engine of a vehicle; determining a plurality of harmonics of the fundamental frequency; and determining a target shape of the plurality of harmonics. The target shape includes, for each of the harmonics of the plurality of the harmonics, a gain value as a function of the RPM of the engine. The method also includes determining an accelerator pedal position (APP) based gain that includes a gain value as a function of an accelerator pedal position; and determining a speed based gain that includes a gain value as a function of a difference between a set maximum speed and a measured vehicle speed. The method further includes combining the plurality of harmonics, the target shape of the plurality of harmonics, the APP based gain, and the speed based gain to produce a set of engine harmonic enhancement signals.
