My sister just purchased a 2021 M340i and I noticed a couple differences from my 2020. The first is the exhaust note. Mine snap, crackles and pops. Her car is subtle at best. Her 2021 can also choose between a Tachometer or Power gauge (such as the one in the 530e and 2021 540i). Her 2021 with "HiFi audio" doesn't have tweeters as my 2020 with HiFi does and her 2021 Doesn't have a auto stop/start off button... just a bit of information

Thanks, although these are all fairly well documented changes to the '21s.

It appears there was a certain batch of 2021’s that did not have the tweeters. Some have them and I’m pretty sure that’s the standard configuration.

Currently have a '21 on order and couldn't really care less about tweeters or no tweeters. It's the exhaust that bothers me....

Also have a '21 on order and beyond bummed about the exhaust. Added the MPE to be port installed but I still feel like the 2020 sound stock was better than the 2021 with MPE.

From what I'm reading, many BMW models are getting the exhaust sound neutered when programming is updated by dealer or OTA. I will be disappointed if my Z4 gets neutered.
