Off the line, the Panamera 4 hits 100 km/h in 5.45 s versus 5.46 s for the Bmw 840i Gran Coupe. The 0.01 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Panamera 4 is doing 132 km/h against 137 km/h for the Bmw 840i Gran Coupe. The gap is 0.08 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 840i Gran Coupe crosses the line in 13.69 s versus 13.78 s. The 0.08 s gap represents roughly 4 m of track — barely a car length.
Past 400 metres, the Bmw 840i Gran Coupe continues to build its lead. At 600 metres, it runs at 191 km/h versus 184 km/h. At 1,000 metres, the Bmw 840i Gran Coupe finishes in 24.68 s versus 25.22 s, with a 0.54 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph — industry threshold) vs 257 km/h), preventing any comeback.
On paper, the Bmw 840i Gran Coupe combines 333 hp, 500 Nm and 1,815 kg — a clear theoretical edge over the Panamera 4. Yet the Panamera 4 launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the Panamera 4 has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs — exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.
Both rivals are electronically governed, but not at the same level: the Bmw 840i Gran Coupe 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 (5.45 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 0.01 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.
