Off the line, the Model S 85 hits 100 km/h in 5.75 s versus 7.44 s for the Bmw 420i. The instant torque of 599 Nm from the electric motor makes the difference. At this point, the Model S 85 leads by 1.70 s and sits roughly 2 m ahead.
At 200 metres, the Model S 85 is doing 137 km/h against 117 km/h for the Bmw 420i. The gap is 0.67 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model S 85 crosses the line in 13.94 s versus 15.38 s. The 1.44 s gap represents roughly 57 m of track - a gap visible to the naked eye.
Past 400 metres, the Model S 85 continues to build its lead. At 600 metres, it runs at 190 km/h versus 163 km/h. At 1,000 metres, the Model S 85 finishes in 25.17 s versus 28.23 s, with a 3.06 s lead. Despite a higher top speed (238 km/h), the Bmw 420i never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the Model S 85 is capped at 201 km/h, the Bmw 420i at 240 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 1.70 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
