The start: 0 to 100 km/h

Off the line, the M5 CS hits 100 km/h in 3.03 s versus 4.72 s for the Panamera 4S. At this point, the M5 CS leads by 1.69 s and sits roughly 13 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M5 CS is doing 170 km/h against 144 km/h for the Panamera 4S. The gap is 1.45 s. The challenger starts to claw back ground.

At 400 metres standing start, the M5 CS crosses the line in 10.81 s versus 12.88 s. The 2.07 s gap represents roughly 99 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M5 CS continues to build its lead. At 600 metres, it runs at 231 km/h versus 202 km/h. At 1,000 metres, the M5 CS finishes in 19.94 s versus 23.24 s, with a 3.30 s lead. Both vehicles have similar top speeds (295 vs 290 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the M5 CS and the Panamera 4S are governed to 305 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (2.87 kg/hp vs 4.23 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.12 seconds. The 1.69 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
