Like any car owner, I'm always curious what numbers my car will put up in a measured test. In this video I tested my 2021 Model 3 Standard Range Plus (SR+) for an hour or two using a Dragy performance meter. Tests were done on a country road with no other vehicles present to ensure a safe experience. Below are my results. Times shown are the fastest runs that were deemed "valid" by Dragy:

0-60 mph: 5.49 seconds (vs. factory claimed 5.3 seconds)
1/4 Mile: 13.68 seconds
30-50 mph: 1.79 seconds
40-60 mph: 1.92 seconds
50-70 mph: 2.28 seconds
60-80 mph: 2.55 seconds

Battery state of charge at beginning of testing: 95%
Battery state of charge at end of testing: 75%

All in all, impressive numbers for the base model Tesla in 2021! As I stated in the video, 0-60 is not where this car will impress you, it's the midrange acceleration that really wows you, it's so fun! Having said that, I was bummed that my best valid 0-60 run was 5.49 seconds vs. Tesla's claimed 5.3 seconds, especially with a full battery on flat roads. Might just have to try again!
