Off the line, the Model S Performance hits 100 km/h in 2.53 s versus 5.06 s for the 840d xDrive Convertible. The instant torque of 1,139 Nm from the electric motor makes the difference. At this point, the Model S Performance leads by 2.53 s and sits roughly 16 m ahead.
At 200 metres, the Model S Performance is doing 175 km/h against 137 km/h for the 840d xDrive Convertible. The gap is 2.06 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model S Performance crosses the line in 10.31 s versus 13.36 s. The 3.04 s gap represents roughly 136 m of track - a gap visible to the naked eye.
Past 400 metres, the Model S Performance continues to build its lead. At 600 metres, it runs at 244 km/h versus 192 km/h. At 1,000 metres, the Model S Performance finishes in 19.02 s versus 24.31 s, with a 5.30 s lead. Both vehicles have similar top speeds (262 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Model S Performance is capped at 262 km/h, the 840d xDrive Convertible 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.
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 7.89 seconds. The 2.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Model S Performance wins (2,53 s vs 5,06 s).
Model S Performance goes from 0 to 100 km/h in 2,53 seconds (calibrated simulation).
