McLaren 720S vs Xiaomi SU7

Over a standing quarter mile on dry asphalt the McLaren 720S is the quicker car, covering it in 9.96 s at 145.5 mph against the Xiaomi SU7’s 10.96 s — a margin of 1.00 s. To 60 mph the McLaren 720S takes 2.67 s and the Xiaomi SU7 2.78 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.

Each car is trimmed to its own published figures — 10/11 for the McLaren 720S, 6/8 for the Xiaomi SU7 — so a heavier car can still be the quicker one if that is what it tests.

Questions

Is the McLaren 720S or the Xiaomi SU7 faster?
The McLaren 720S. Over a standing quarter mile it runs 9.96 s to the Xiaomi SU7's 10.96 s, a margin of 1.00 s, and it reaches 60 mph in 2.67 s against 2.78 s. These are theoretical times from a physics simulation, not measured runs.
What is the McLaren 720S 0-60 time?
The McLaren 720S reaches 60 mph in 2.67 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 9.96 s at 145.5 mph.
What is the Xiaomi SU7 0-60 time?
The Xiaomi SU7 reaches 60 mph in 2.78 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 10.96 s at 126.1 mph.
What trap speed does each car run?
The McLaren 720S trips the lights at 145.5 mph and the Xiaomi SU7 at 126.1 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 — 10 of 11 for the McLaren 720S and 6 of 8 for the Xiaomi SU7. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
