2018 Mustang’s Heart Beat

The 2018 Mustang will bring about many changes to the interior when it debuts in showrooms this Fall. That includes a new 12-inch fully digital and customizable instrument cluster, and as is customary, a few Easter eggs that carry forward the pony car metaphor.

One of these hidden features is a new ignition start button that is encased in a spun aluminum ring. At first glance it appears to be the same one offered in the 2015-17 Mustang, but once the door is unlocked, the new start button and the words “Engine,” “Start” and “Stop” engraved on it begin to pulse red at a rate of 30 beats per minute to mimic the resting heart rate of a pony — until the powerful engine is started.

When it comes to Ford’s iconic pony car, many of its undocumented features add to the charisma of the Mustang and this is just another in the latest of what are sure to be more hidden gems for the S550 Mustang refresh.
