G9 vs Bmw 330i Sedan: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 330i Sedan hits 100 km/h in 5.93 s versus 8.51 s for the G9. Despite lacking instant torque, 258 hp of power compensates. At this point, the Bmw 330i Sedan leads by 2.58 s and sits roughly 27 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 330i Sedan is doing 134 km/h against 120 km/h for the G9. The gap is 1.65 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 330i Sedan crosses the line in 14.10 s versus 16.32 s. The 2.22 s gap represents roughly 89 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 330i Sedan continues to build its lead. At 600 metres, it runs at 189 km/h versus 169 km/h. At 1,000 metres, the Bmw 330i Sedan finishes in 25.22 s versus 28.71 s, with a 3.49 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the G9 is capped at 200 km/h, the Bmw 330i Sedan at 250 km/h. This isn’t a physical engine limit — it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.63 seconds. The 2.58 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 330i Sedan has a clear edge over the Xpeng G9 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
