Off the line, the Z4 M40i hits 100 km/h in 4.54 s versus 9.34 s for the 218i Convertible. At this point, the Z4 M40i leads by 4.80 s and sits roughly 25 m ahead.
At 200 metres, the Z4 M40i is doing 147 km/h against 110 km/h for the 218i Convertible. The gap is 2.62 s. The challenger starts to claw back ground.
At 400 metres standing start, the Z4 M40i crosses the line in 12.70 s versus 16.78 s. The 4.09 s gap represents roughly 146 m of track - a gap visible to the naked eye.
Past 400 metres, the Z4 M40i continues to build its lead. At 600 metres, it runs at 205 km/h versus 154 km/h. At 1,000 metres, the Z4 M40i finishes in 22.95 s versus 30.47 s, with a 7.52 s lead.
Both rivals are electronically governed, but not at the same level: the Z4 M40i 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.51 kg/hp vs 11.47 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.16 seconds. The 4.80 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
