Off the line, the Bmw 840i hits 100 km/h in 4.95 s versus 5.45 s for the Panamera 4. At this point, the Bmw 840i leads by 0.50 s and sits roughly 1 m ahead.
At 200 metres, the Bmw 840i is doing 142 km/h against 132 km/h for the Panamera 4. The gap is 0.29 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840i crosses the line in 13.15 s versus 13.78 s. The 0.63 s gap represents roughly 28 m of track — two to three car lengths.
Past 400 metres, the Bmw 840i continues to build its lead. At 600 metres, it runs at 198 km/h versus 184 km/h. At 1,000 metres, the Bmw 840i finishes in 23.75 s versus 25.22 s, with a 1.47 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph — industry threshold) vs 257 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 840i is capped at 250 (i.e. 155 mph — industry threshold) km/h, the Panamera 4 at 257 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 (5.03 kg/hp vs 6.08 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.74 seconds. The 0.50 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.
