Off the line, the 911 Carrera 4 hits 100 km/h in 4.90 s versus 5.08 s for the Boxster S. At this point, the 911 Carrera 4 leads by 0.18 s and sits roughly 3 m ahead.
At 200 metres, the 911 Carrera 4 is doing 147 km/h against 143 km/h for the Boxster S. The gap is 0.20 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera 4 crosses the line in 12.85 s versus 13.23 s. The 0.38 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the 911 Carrera 4 continues to build its lead. At 600 metres, it runs at 209 km/h versus 198 km/h. At 1,000 metres, the 911 Carrera 4 finishes in 22.96 s versus 23.87 s, with a 0.91 s lead.
The 911 Carrera 4 features all-wheel drive (AWD) against the Boxster S’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.
Both rivals are electronically governed, but not at the same level: the 911 Carrera 4 is capped at 285 km/h, the Boxster S at 274 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.03 kg/hp vs 4.32 kg/hp) and transmission (Manual vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.45 seconds. The 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
