Off the line, the 911 Carrera Cab hits 100 km/h in 4.52 s versus 4.55 s for the Z4 M40i. The 0.03 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 911 Carrera Cab is doing 148 km/h against 147 km/h for the Z4 M40i. The gap is 0.04 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera Cab crosses the line in 12.62 s versus 12.71 s. The 0.10 s gap represents roughly 5 m of track - barely a car length.
Past 400 metres, the 911 Carrera Cab continues to build its lead. At 600 metres, it runs at 208 km/h versus 204 km/h. At 1,000 metres, the 911 Carrera Cab finishes in 22.72 s versus 23.00 s, with a 0.27 s lead.
Both rivals are electronically governed, but not at the same level: the 911 Carrera Cab is capped at 289 km/h, the Z4 M40i at 250 (i.e. 155 mph - industry threshold) 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 (4.29 kg/hp vs 4.57 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.79 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
