Off the line, the Panamera 4 hits 100 km/h in 5.45 s versus 5.57 s for the 840i Convertible. At this point, the Panamera 4 leads by 0.12 s and sits roughly 6 m ahead.
At 200 metres, the Panamera 4 is doing 132 km/h against 136 km/h for the 840i Convertible. The gap is 0.15 s. The gap remains stable from the start.
At 400 metres standing start, the Panamera 4 crosses the line in 13.78 s versus 13.79 s. The 0.01 s gap represents roughly 1 m of track
Past 400 metres, the situation changes. The 840i Convertible maxes out at 250 (i.e. 155 mph - industry threshold) km/h while the Panamera 4 keeps accelerating towards 257 km/h. At 600 metres, the gap has dropped to 0.13 s.
Around 420 metres, both vehicles are level. This is the inversion point: the 840i Convertible overcomes its launch deficit thanks to a 7 km/h higher top speed.
At 1,000 metres, the 840i Convertible finishes in 24.82 s versus 25.22 s. The 0.40 s delta shows an extremely tight race.
On paper, the 840i Convertible combines 333 hp, 500 Nm and 1,840 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 840i Convertible 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 (5.53 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 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
