Off the line, the M4 Competition Convertible hits 100 km/h in 4.43 s versus 9.57 s for the 218i Convertible. At this point, the M4 Competition Convertible leads by 5.14 s and sits roughly 29 m ahead.
At 200 metres, the M4 Competition Convertible is doing 148 km/h against 109 km/h for the 218i Convertible. The gap is 2.89 s. The challenger starts to claw back ground.
At 400 metres standing start, the M4 Competition Convertible crosses the line in 12.51 s versus 17.01 s. The 4.51 s gap represents roughly 157 m of track - a gap visible to the naked eye.
Past 400 metres, the M4 Competition Convertible continues to build its lead. At 600 metres, it runs at 209 km/h versus 150 km/h. At 1,000 metres, the M4 Competition Convertible finishes in 22.55 s versus 30.99 s, with a 8.44 s lead.
Both rivals are electronically governed, but not at the same level: the M4 Competition Convertible 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 (3.98 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 15.88 seconds. The 5.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 Competition Convertible F82 wins (4,43 s vs 9,57 s).
M4 Competition Convertible F82 goes from 0 to 100 km/h in 4,43 seconds (calibrated simulation).
