The Fast Lane Car shows us the new BMW i8 and the new 2015 Ford Mustang with the 2.3L I4 Ecoboost. Why? Both vehicles have at least one thing in common.

The audio systems in both vehicles are used to enhance the vehicle's engine and exhaust noise. "For those almost V8-like sounds".

We will use the term "Enhanced Audio," as "fake" might sound a little harsh.

Understandable, perhaps...you may or may not enjoy the sound a typical 4 cylinder makes. Not too many 3 cylinder vehicles are out there, but that's what the i8 features.

Especially in vehicles such as the Mustang and the i8…most owners want it to sound, for lack of a better word, sweeeeett! It appears that the audio enhancements are to add to the enjoyment and thrill that you can get with both vehicles.

There seems to be many mixed emotions with the audio system enhancing the engine and exhaust notes. Some like it, some don't. What are your thoughts?
