We have 2018 i3 and the lease is coming up in September. My wife is insisting on leasing another 2021 i3 (but as much as I love the unique style and the fun to drive it, I can't justify the price and the awful range anymore over Model 3). Anyways, didn't know that even new US models make this stupid sound, thought it was just an EU regulation. Subscribing to the thread for future use
