Thanks Geoffrey for the link. That was very interesting. I like seeing those technical systems, which is why I have worked the Formula E races. The technical side makes up for the loud V-8 sounds. In 2019 I worked at Pit In, which was also at the last corner on the front straight. As the cars accelerated down the front straight, just a few feet from me, they sounded like the Storm Troopers from Star Wars. A much better sound than the 1st Generation cars.
With all of that said, I did not buy a Mustang Mach E last year, I got a Mustang Mach 1 with 5.0L, V8, 480 HP and active exhaust. That means it has 4 levels of sound; Quiet, which is quieter than Denise's '06 Mustang GT with V-8. Then there is Normal, Sport, and of course Track, all can be changed on the steering wheel controls.
Quiet is used to back out of the garage and go down the street to not annoy the neighbors with the raw HP.
