The start: 0 to 100 km/h

Off the line, the Maybach S 680 hits 100 km/h in 4.53 s versus 5.60 s for the ActiveHybrid X6. At this point, the Maybach S 680 leads by 1.06 s and sits roughly 14 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Maybach S 680 is doing 153 km/h against 141 km/h for the ActiveHybrid X6. The gap is 0.87 s. The challenger starts to claw back ground.

At 400 metres standing start, the Maybach S 680 crosses the line in 12.41 s versus 13.66 s. The 1.26 s gap represents roughly 60 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Maybach S 680 continues to build its lead. At 600 metres, it runs at 220 km/h versus 198 km/h. At 1,000 metres, the Maybach S 680 finishes in 21.93 s versus 24.29 s, with a 2.36 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 236 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Maybach S 680 is capped at 250 (i.e. 155 mph - industry threshold) km/h, the ActiveHybrid X6 at 236 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 (3.86 kg/hp vs 5.05 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.07 seconds. The 1.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
