Available on the Ford Mustang, including EcoBoost, is Active Performance Exhaust Audio Engineering. It boasts highly specialized computers that control the opening of engine exhaust valves. Why is this wonderful? Our Dover, DE Winner Ford team explains.
Engine Roar 101
Most engine roar happens when engine exhaust valves open wide. Doing so lets in high-pressure gas, creating sound waves that hit the ear like a roar. Aren't beefy sports cars supposed to have ridiculous engine roar? Of course, they are, but this roar isn't always welcomed in dead silent neighborhoods during the wee hours. Active Performance Exhaust Audio Engineering modes adjust engine roar according to where you are and/or how you feel. Track, Sport, Normal and Quiet Start are the modes.
Altering Engine 'Notes'
Active Performance Exhaust Audio Engineering's specialized computers do more than just control engine exhaust valves. They open the valves to very specific degrees, in unique arrangements, rather like a saxophonist manipulates valves to elicit gorgeous resonance from brass. This improves the engine's 'notes,' creating the sort of classic engine racecar sound you expect from the Ford Mustang.
