The start: 0 to 100 km/h

Off the line, the 911 Carrera Cab hits 100 km/h in 4.52 s versus 4.77 s for the 911 Carrera (Manual). At this point, the 911 Carrera Cab leads by 0.25 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera Cab is doing 148 km/h against 148 km/h for the 911 Carrera (Manual). The gap is 0.19 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 12.81 s. The 0.19 s gap represents roughly 10 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera Cab continues to build its lead. At 600 metres, it runs at 208 km/h versus 209 km/h. At 1,000 metres, the 911 Carrera Cab finishes in 22.72 s versus 22.88 s, with a 0.16 s lead. Both vehicles have similar top speeds (289 vs 289 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 911 Carrera Cab and the 911 Carrera (Manual) are governed to 289 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.29 kg/hp vs 4.13 kg/hp) and transmission (Unknown vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.09 seconds. The 0.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
