We tracked our new 2021 BMW M3 dubbed "Project Senna" in 100% stock form at Buttonwillow CW13 to set a baseline time.
We're pleased to report that the G80 M3's amazing braking, handling, and power delivery allowed us to run multiple 1:57 laps 6x times in a row with the fastest lap at 1:57.444 in one of the sessions in the early afternoon.
With a lot of fast drivers out on track this day, we had maybe 3 completely open laps and our fastest lap was completed with traffic in the back sweeper. Our lap timer's predictive lap was showing a 1:55 during this lap before we had to pass the Cayman!
