The start: 0 to 100 km/h

Off the line, the Panamera 4 E-Hybrid hits 100 km/h in 4.56 s versus 5.75 s for the S 450 e Saloon. At this point, the Panamera 4 E-Hybrid leads by 1.19 s and sits roughly 15 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Panamera 4 E-Hybrid is doing 143 km/h against 138 km/h for the S 450 e Saloon. The gap is 0.80 s. The challenger starts to claw back ground.

At 400 metres standing start, the Panamera 4 E-Hybrid crosses the line in 12.86 s versus 13.80 s. The 0.94 s gap represents roughly 44 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Panamera 4 E-Hybrid continues to build its lead. At 600 metres, it runs at 198 km/h versus 197 km/h. At 1,000 metres, the Panamera 4 E-Hybrid finishes in 23.49 s versus 24.46 s, with a 0.97 s lead.

What the numbers don’t tell you

The Panamera 4 E-Hybrid 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 Panamera 4 E-Hybrid is capped at 278 km/h, the S 450 e Saloon at 250 (i.e. 155 mph - industry threshold) 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 (4.93 kg/hp vs 5.67 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.38 seconds. The 1.19 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
