The start: 0 to 100 km/h

Off the line, the 911 Carrera (Manual) hits 100 km/h in 4.77 s versus 5.60 s for the ActiveHybrid X6. At this point, the 911 Carrera (Manual) leads by 0.83 s and sits roughly 12 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera (Manual) is doing 148 km/h against 141 km/h for the ActiveHybrid X6. The gap is 0.63 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Carrera (Manual) crosses the line in 12.81 s versus 13.66 s. The 0.86 s gap represents roughly 41 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera (Manual) 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 (Manual) finishes in 22.88 s versus 24.29 s, with a 1.40 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the ActiveHybrid X6 is capped at 236 km/h, the 911 Carrera (Manual) 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.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.05 kg/hp vs 4.13 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.07 seconds. The 0.83 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
