Off the line, the 911 GT3 hits 100 km/h in 4.08 s versus 5.72 s for the Boxster. At this point, the 911 GT3 leads by 1.64 s and sits roughly 14 m ahead.
At 200 metres, the 911 GT3 is doing 158 km/h against 132 km/h for the Boxster. The gap is 1.34 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 13.99 s. The 2.14 s gap represents roughly 94 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 GT3 continues to build its lead. At 600 metres, it runs at 225 km/h versus 187 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 25.24 s, with a 4.01 s lead.
Electronically capped at 262 km/h, the Boxster 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.16 kg/hp vs 5.15 kg/hp) and transmission (Manual vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.00 seconds. The 1.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
