One of the things Ford is doing to help tie the style of the Mustang Mach-E to the styling of the real Mustang is to give it a front grill area that looks very similar to the Mustang muscle car. Mustangs have had sequential turn signals for multiple model years, and they are popular aftermarket upgrades for vehicles that didn’t come with sequential turn signals from the factory. With that in mind, it’s no surprise that Ford has fitted the Mach-E with sequential rear turn signals.
The animated gif image below shows the sequential turn signals in action. It appears to us that the animation is running faster than real-time, hence the cars moving like they are on fast forward and the speed of the turn signal moving. As for why it appears that the red section under the tail light on the right is flashing, we assume that to be an artifact of the way LED lights are picked up on camera. We see this routinely with any vehicle with LED lights captured on video.
We would like to know why so many of the Mustang Mach-E cars we’ve seen have white lift gates. It doesn’t appear to be camo, and the vehicle has been officially unveiled, but perhaps this is an older image from before the reveal.
Ford has bet big on the Mustang Mach-E aiming directly at the Tesla Model Y crossover. Recently we learned that the Mach-E and the electric Transit van would share the same battery pack. Sharing the battery pack between two models allows Ford to run the battery line at capacity and lower cost.
