The start: 0 to 100 km/h

Off the line, the X9 hits 100 km/h in 3.88 s versus 4.52 s for the 911 Carrera Cab. The instant torque of 717 Nm from the electric motor makes the difference. At this point, the X9 leads by 0.63 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the X9 is doing 173 km/h against 148 km/h for the 911 Carrera Cab. The gap is 0.73 s. The gap remains stable from the start.

At 400 metres standing start, the X9 crosses the line in 11.34 s versus 12.62 s. The 1.28 s gap represents roughly 64 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The X9 maxes out at 200 km/h while the 911 Carrera Cab keeps accelerating towards 289 km/h. At 600 metres, the gap has dropped to 1.33 s.

At 1,000 metres, the X9 finishes in 22.13 s versus 22.72 s, with just 0.59 s to spare. The 911 Carrera Cab fails to fully close the launch gap.

What the numbers don’t tell you

The X9 features all-wheel drive (AWD) against the 911 Carrera Cab’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 X9 is capped at 200 km/h, the 911 Carrera Cab at 289 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.73 seconds. The 0.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
