Tesla Model S Plaid vs Xiaomi SU7 Ultra

Over a standing quarter mile on dry asphalt the Xiaomi SU7 Ultra is the quicker car, covering it in 9.22 s at 160.6 mph against the Tesla Model S Plaid’s 9.57 s — a margin of 0.35 s. To 60 mph the Xiaomi SU7 Ultra takes 2.31 s and the Tesla Model S Plaid 2.04 s.

Simulated, not measured — computed from each car’s published kerb mass, rated power and drivetrain, then fitted to its own published acceleration figures. Dry asphalt, 20 °C, sea level, 1 ft rollout.

Questions

Is the Tesla Model S Plaid or the Xiaomi SU7 Ultra faster?
The Xiaomi SU7 Ultra. Over a standing quarter mile it runs 9.22 s to the Tesla Model S Plaid's 9.57 s, a margin of 0.35 s, and it reaches 60 mph in 2.31 s against 2.04 s. These are theoretical times from a physics simulation, not measured runs.
What is the Tesla Model S Plaid 0-60 time?
The Tesla Model S Plaid reaches 60 mph in 2.04 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 9.57 s at 145.9 mph.
What is the Xiaomi SU7 Ultra 0-60 time?
The Xiaomi SU7 Ultra reaches 60 mph in 2.31 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 9.22 s at 160.6 mph.
What trap speed does each car run?
The Tesla Model S Plaid trips the lights at 145.9 mph and the Xiaomi SU7 Ultra at 160.6 mph at the end of the quarter mile. These are theoretical times from a physics simulation, not measured runs.
Are these real measured times?
No. Every time on this page is produced by a physics simulation, not by a stopwatch at a drag strip. Each car is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it matches its own published acceleration figures — 11 of 11 for the Tesla Model S Plaid and 8 of 11 for the Xiaomi SU7 Ultra. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
