Off the line, the Panamera 4 hits 100 km/h in 5.45 s versus 5.49 s for the Bmw 840i Gran Coupe. The 0.04 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Panamera 4 is doing 132 km/h against 135 km/h for the Bmw 840i Gran Coupe. The gap is 0.07 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 840i Gran Coupe crosses the line in 13.72 s versus 13.78 s. The 0.05 s gap represents roughly 3 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 189 km/h versus 184 km/h. At 1,000 metres, the Bmw 840i Gran Coupe finishes in 24.81 s versus 25.22 s, with a 0.41 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 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
