Off the line, the Panamera hits 100 km/h in 5.28 s versus 5.36 s for the Bmw 840i Convertible. The 0.08 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Panamera is doing 136 km/h against 137 km/h for the Bmw 840i Convertible. The gap is 0.03 s. The gap remains stable from the start.
At 400 metres standing start, the Panamera crosses the line in 13.57 s versus 13.59 s. The 0.01 s gap represents roughly 1 m of track
Past 400 metres, the situation changes. The Bmw 840i Convertible maxes out at 250 (i.e. 155 mph — industry threshold) km/h while the Panamera keeps accelerating towards 264 km/h. At 600 metres, the gap has dropped to 0.02 s.
Around 481 metres, both vehicles are level. This is the inversion point: the Bmw 840i Convertible overcomes its launch deficit thanks to a 14 km/h higher top speed.
At 1,000 metres, the Bmw 840i Convertible finishes in 24.56 s versus 24.66 s. The 0.10 s delta shows an extremely tight race.
Both rivals are electronically governed, but not at the same level: the Bmw 840i Convertible is capped at 250 (i.e. 155 mph — industry threshold) km/h, the Panamera at 264 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 (5.38 kg/hp vs 5.42 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.22 seconds. The 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
Sur 0–100 km/h, Panamera 971 gagne (5,28 s vs 5,36 s).
