Off the line, the i7 xDrive60 hits 100 km/h in 4.66 s versus 4.69 s for the M4 Convertible. The instant torque of 745 Nm from the electric motor makes the difference. The 0.03 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the M4 Convertible is doing 151 km/h against 145 km/h for the i7 xDrive60. The gap is 0.02 s. The gap remains stable from the start.
At 400 metres standing start, the M4 Convertible crosses the line in 12.64 s versus 12.86 s. The 0.22 s gap represents roughly 11 m of track - two to three car lengths.
Past 400 metres, the M4 Convertible continues to build its lead. At 600 metres, it runs at 213 km/h versus 203 km/h. At 1,000 metres, the M4 Convertible finishes in 22.51 s versus 23.17 s, with a 0.65 s lead. Both vehicles have similar top speeds (240 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the i7 xDrive60 is capped at 240 km/h, the M4 Convertible 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.
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 6.94 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, i7 xDrive60 G70 and M4 Convertible F82 are neck and neck (4,66 s vs 4,69 s, no significant gap).
i7 xDrive60 G70 goes from 0 to 100 km/h in 4,66 seconds (calibrated simulation).
