911 Turbo vs P7: chronicle of a drag race at 311 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Turbo hits 100 km/h in 3.53 s versus 4.22 s for the P7. Despite lacking instant torque, 507 hp of power compensates. At this point, the 911 Turbo leads by 0.69 s and sits roughly 4 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Turbo is doing 168 km/h against 147 km/h for the P7. The gap is 0.66 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Turbo crosses the line in 11.25 s versus 12.54 s. The 1.29 s gap represents roughly 61 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Turbo continues to build its lead. At 600 metres, it runs at 233 km/h versus 170 km/h. At 1,000 metres, the 911 Turbo finishes in 20.27 s versus 25.24 s, with a 4.97 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Turbo is capped at 312 km/h, the P7 at 170 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 6.49 seconds. The 0.69 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Turbo has a clear edge over the Xpeng P7 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
