2021 M340i xDrive
- The throttle and transmission mapping on the BMW is superior because of how linear the response is. The Audi is a lot more laggy and it took me a while to get used to driving it. It had an annoying lag in D mode that I never really fell in love with. In S mode it was nicely twitchy but that's not always fun in heavy traffic. Audi sadly hasn't been to bridge the gap between the two modes where BMW has. The BMW is extremely smooth to the point where it's dangerously deceptive on how fast you're going.
- Audi wins in the interior for me. Other than the subjective design language, there are more soft touch materials were your hands would normally touch.
- The 48v mild hybrid in the 2021 is a game changer for start and stop. I always turned it off in the S5 because of how abrupt it was. No issues in the M340i. Also they took away the button to turn it off but I don't miss it. All cars with start stop need to have a mild hybrid system. Anything less is criminal.
- The adaptive suspension is more comfortable in the Audi than in the BMW. I did get the Adaptive M Suspension option. Can't imagine going with the regular suspension, as it's supposed to be even firmer.
