The start: 0 to 100 km/h

Off the line, the 745e hits 100 km/h in 5.16 s versus 9.45 s for the 218i Convertible. The instant torque of 600 Nm from the electric motor makes the difference. At this point, the 745e leads by 4.29 s and sits roughly 18 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 745e is doing 139 km/h against 107 km/h for the 218i Convertible. The gap is 1.98 s. The challenger starts to claw back ground.

At 400 metres standing start, the 745e crosses the line in 13.37 s versus 16.81 s. The 3.44 s gap represents roughly 119 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 745e continues to build its lead. At 600 metres, it runs at 196 km/h versus 148 km/h. At 1,000 metres, the 745e finishes in 24.07 s versus 31.02 s, with a 6.94 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 745e is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 218i Convertible at 207 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 16.40 seconds. The 4.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
