There are many updates to the 2018 Ford Mustang, but one surprise new feature is a pulsing start button that literally pulses like a heartbeat once the door is unlocked and until the driver pushes it.

The pulsing start button, pulses at a rate of 30 beats per minute, which mirrors the resting heart rate of a pony. On the backlit button, the words “Engine,” “Start” and “Stop” glow red.

The new start button is just one of the new features/ updates to the 2018 Mustang lineup, which also gets a 12-inch digital instrument cluster, an available 10-speed automatic transmission, and a redesigned front and rear end. Under the hood, the base V6 is now gone, which means that the turbocharged 2.3L four-cylinder will be the base engine. The V8 in the Mustang GT has also been updated to give it more power.
