Off the line, the Bmw 840i Convertible hits 100 km/h in 5.36 s versus 5.77 s for the Panamera 4. The 0.41 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw 840i Convertible is doing 137 km/h against 128 km/h for the Panamera 4. The gap is 0.20 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840i Convertible crosses the line in 13.59 s versus 14.11 s. The 0.52 s gap represents roughly 23 m of track - two to three car lengths.
Past 400 metres, the Bmw 840i Convertible continues to build its lead. At 600 metres, it runs at 191 km/h versus 177 km/h. At 1,000 metres, the Bmw 840i Convertible finishes in 24.56 s versus 25.94 s, with a 1.39 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 247 km/h), preventing any comeback.
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 4 at 256 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 5.99 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.39 seconds. The 0.41 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.
