Fine print

Tesla's 0.81 s is a manufacturer claim from its reveal-night demo with the rear thrusters firing, on a car that doesn't ship until 2028. BYD has published no acceleration figures for the U9 Xtreme. The 2.28 s we use is the standard, 960 kW U9's claim of 2.36 s to 100 km/h, converted to 60 mph, so the Xtreme is probably a little quicker than the page shows. The Xtreme's own title is top speed: 308 mph, the fastest production car.

The animation assumes constant acceleration from a standing start, then holds 60 mph. Real launches aren't perfectly linear, but it's close enough for a picture. The 3.4 g figure is that same average, not a peak.
