CONFIDENCE 90%The P7 reaches 100 km/h first (4.21 s vs 4.58 s), but the Boxster Spyder is ahead at every metre of the race. Explanation: the Boxster Spyder accelerates harder at low speed and builds a distance gap before either car hits 100 km/h.
Why this result?
The Xpeng P7 is faster at 0-100 km/h, but the Porsche Boxster Spyder compensates at high speed thanks to higher peak power or top speed. At 400 m, Porsche Boxster Spyder leads by 0.14 s.

P7 vs Boxster Spyder: chronicle of a drag race at 288 km/h
The launch: 0 to 100 km/h
Off the line, the P7 hits 100 km/h in 4.22 s versus 4.59 s for the Boxster Spyder. The instant torque of 655 Nm from the electric motor makes the difference. At this point, the P7 leads by 0.37 s and sits roughly 7 m ahead.
From 100 km/h to 400 metres
At 200 metres, the P7 is doing 147 km/h against 154 km/h for the Boxster Spyder. The gap is 0.17 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster Spyder crosses the line in 12.41 s versus 12.54 s. The 0.14 s gap represents roughly 6 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Boxster Spyder continues to build its lead. At 600 metres, it runs at 216 km/h versus 170 km/h. At 1,000 metres, the Boxster Spyder finishes in 22.15 s versus 25.24 s, with a 3.09 s lead.
What the numbers don’t tell you
The P7 features all-wheel drive (AWD) against the Boxster Spyder’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
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 6.54 seconds. The 0.37 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Xpeng P7 is slightly faster than the Porsche Boxster Spyder to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
