Off the line, the Bmw 840i Convertible hits 100 km/h in 5.57 s versus 5.81 s for the Model 3 Standard Range Plus. Despite lacking instant torque, 333 hp of power compensates. The 0.24 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw 840i Convertible is doing 136 km/h against 129 km/h for the Model 3 Standard Range Plus. The gap is 0.12 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840i Convertible crosses the line in 13.79 s versus 14.26 s. The 0.47 s gap represents roughly 20 m of track - two to three car lengths.
Past 400 metres, the Bmw 840i Convertible continues to build its lead. At 600 metres, it runs at 190 km/h versus 171 km/h. At 1,000 metres, the Bmw 840i Convertible finishes in 24.82 s versus 26.61 s, with a 1.79 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 840i Convertible is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Model 3 Standard Range Plus at 225 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 9.43 seconds. The 0.24 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 840i Convertible G15 wins (5,57 s vs 5,81 s).
