The start: 0 to 100 km/h

Off the line, the Model S P85D hits 100 km/h in 3.33 s versus 3.34 s for the RS e-tron GT. The 0.01 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the Model S P85D is doing 167 km/h against 167 km/h for the RS e-tron GT. The gap is 0.01 s. The gap remains stable from the start.

At 400 metres standing start, the RS e-tron GT crosses the line in 11.17 s versus 11.17 s. The 0.01 s gap represents roughly 0 m of track

Beyond 400 metres: top speed comes into play

Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.04 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the RS e-tron GT and the Model S P85D are governed to 250 (i.e. 155 mph - industry threshold) 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 electric powertrains, the difference comes down to power-to-weight ratio (3.25 kg/hp vs 3.24 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 4.78 seconds. The 0.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
