Boxster S vs P7: chronicle of a drag race at 252 km/h
The launch: 0 to 100 km/h
Off the line, the Boxster S hits 100 km/h in 5.17 s versus 6.58 s for the P7. Despite lacking instant torque, 310 hp of power compensates. At this point, the Boxster S leads by 1.42 s and sits roughly 15 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Boxster S is doing 141 km/h against 127 km/h for the P7. The gap is 0.96 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster S crosses the line in 13.32 s versus 14.81 s. The 1.49 s gap represents roughly 63 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Boxster S continues to build its lead. At 600 metres, it runs at 197 km/h versus 170 km/h. At 1,000 metres, the Boxster S finishes in 23.98 s versus 27.64 s, with a 3.66 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Boxster S is capped at 274 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 10.18 seconds. The 1.42 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Boxster S 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.
