So we live near the Smoky Mountains which is the perfect place to take the Tesla for the day. There is a motor trail (Roaring Fork Motor Nature Trail) behind the tourist trap city of Gatlinburg, TN. It's a 5.5 mile one way loop that winds drivers through the forest and I'd say has an elevation change of a few hundred feet from start to end. The average speed along the trail is probably around 10mph or less if you're taking the time to view the scenery and occasional black bears.
Both times that we've taken the Tesla (2022 M3LR), towards the end of the trail, the whine of the motors got much louder and had a different pitch to them which I mistook for a distant emergency vehicle siren without the change in tone. When I gave it some "gas" along parts of the trail where it was flat or uphill, the noise mostly went away but came back when going downhill even slightly.
It kinda freaked me out the 1st time and figured something was wrong with the car that I had to make an appointment for but by the time we got back into Gatlinburg, the noise went away. It was almost like the motors were dealing with too much regenerative braking even though we were under 10mph the entire time. Is this Tesla's version of what happens to the brakes of ICE cars when using too much brake pedal going down long mountain roads?
