The start: 0 to 100 km/h

Off the line, the Boxster Spyder hits 100 km/h in 4.59 s versus 4.77 s for the 911 Carrera (Manual). At this point, the Boxster Spyder leads by 0.18 s and sits roughly 2 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Boxster Spyder is doing 154 km/h against 148 km/h for the 911 Carrera (Manual). The gap is 0.23 s. The gap remains stable from the start.

At 400 metres standing start, the Boxster Spyder crosses the line in 12.41 s versus 12.81 s. The 0.40 s gap represents roughly 20 m of track - two to three car lengths.

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 209 km/h. At 1,000 metres, the Boxster Spyder finishes in 22.15 s versus 22.88 s, with a 0.73 s lead. Both vehicles have similar top speeds (288 vs 289 km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 289 km/h, the 911 Carrera (Manual) 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 (3.51 kg/hp vs 4.13 kg/hp) and transmission (Manual vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.09 seconds. The 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
