Off the line, the P7 hits 100 km/h in 4.22 s versus 5.75 s for the S 450 e Saloon. At this point, the P7 leads by 1.53 s and sits roughly 17 m ahead.
At 200 metres, the P7 is doing 147 km/h against 138 km/h for the S 450 e Saloon. The gap is 1.05 s. The challenger starts to claw back ground.
At 400 metres standing start, the P7 crosses the line in 12.54 s versus 13.80 s. The 1.25 s gap represents roughly 59 m of track - a gap visible to the naked eye.
Past 400 metres, the situation changes. The P7 maxes out at 170 km/h while the S 450 e Saloon keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.91 s.
Around 842 metres, both vehicles are level. This is the inversion point: the S 450 e Saloon overcomes its launch deficit thanks to a 80 km/h higher top speed.
At 1,000 metres, the S 450 e Saloon finishes in 24.46 s versus 25.24 s. The 0.79 s delta in favour of the S 450 e Saloon shows that top speed makes a clear difference.
The P7 features all-wheel drive (AWD) against the S 450 e Saloon’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the S 450 e Saloon is capped at 250 (i.e. 155 mph - industry threshold) km/h, the P7 at 170 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (5.67 kg/hp vs 4.81 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.38 seconds. The 1.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, P7 wins (4,21 s vs 5,75 s).
S 450 e Saloon W223 goes from 0 to 100 km/h in 5,75 seconds (calibrated simulation).
