2021 Mazda 3 Turbo
Went frame-by-frame to line up the exact moment the foot was let off the brake and the exact moment when each car hit 60.
Turbo manages to get to 60 in 6.8 seconds.
91 octane & not broken-in.
NA manages it in 7.9 seconds.
87 octane + brake boost, ~25,000 miles on the odometer.
93 octane + brake boost & 36,000 miles on the odometer, I can reliably get 7.6 seconds.
The 0-60 is not that much quicker than the NA, but the Turbo seems to have a significant advantage at pulling over 60 mph.
The NA does pretty well up to 60 (1st and 2nd gear), but from 3rd, the acceleration diminishes quickly.
UPDATE: [email protected] posted a 0-60 tracked clip with a time of 5.75 seconds.
