What we know / assumptions
Here’s what we know or can estimate about each car.
Tesla Model S Plaid
- Powertrain: Triple-motor electric drivetrain.
- 0–60 mph (0–100 km/h): ~2.0 seconds (manufacturer claim / measured)
- Quarter mile: ~9.2 seconds in some real runs.
- Very high torque delivery (instant from 0).
Xiaomi SU7 Ultra
This is less familiar. Xiaomi is known for electronics, but apparently “SU7 Ultra” is a model of electric vehicle (EV). Its drag performance would depend heavily on:
- Motor and battery specs (power, torque)
- Power delivery / traction / wheelspin control
- Weight / aerodynamics
I could not immediately find widely published drag times for “Xiaomi SU7 Ultra” in my memory base.
What to expect in a drag race: key factors
- Torque & power output — The one with better power-to-weight and torque will generally win from a roll or launch.
- Traction / launch control — Even with more power, if the car can’t put the torque to the ground, it'll lose or have a bad start.
- Weight and aerodynamics — Over longer distance (quarter mile or more), drag, weight, and efficiency matter.
- Battery performance / power delivery under load — Some EVs lose performance when battery heat or current limits kick in.
So even if the SU7 Ultra is very powerful, the question is: can it out-launch or sustain enough power against the Plaid?
What the video claim suggests & plausibility
If the video claims the Xiaomi SU7 Ultra beats (or nearly matches) the Tesla Model S Plaid in a straight drag, possibilities:
- The Xiaomi has a very aggressive tuning / high power output.
- The test is in ideal conditions (launch assist, traction, driver skill).
- The Plaid in that particular run might have been limited (battery temp, tire grip, etc.).
- The video might be exaggerated or selectively edited (slow start, favorable conditions, etc.).
