Porsche 911 R 991.2 vs Xpeng P7 : which one is faster?

The launch: 0 to 100 km/h

Off the line, the 911 R hits 100 km/h in 3.78 s versus 4.22 s for the P7. Despite lacking instant torque, 500 hp of power compensates. At this point, the 911 R leads by 0.44 s and sits roughly 2 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 R is doing 166 km/h against 147 km/h for the P7. The gap is 0.52 s. The gap remains stable from the start.

At 400 metres standing start, the 911 R crosses the line in 11.38 s versus 12.54 s. The 1.17 s gap represents roughly 55 m of track — a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 R continues to build its lead. At 600 metres, it runs at 239 km/h versus 170 km/h. At 1,000 metres, the 911 R finishes in 20.19 s versus 25.24 s, with a 5.05 s lead.

What the numbers don’t tell you

Electronically capped at 170 km/h, the P7 never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

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 0.44 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
