The start: 0 to 100 km/h

Off the line, the M4 Competition Coupe hits 100 km/h in 3.94 s versus 7.69 s for the 220i Convertible. At this point, the M4 Competition Coupe leads by 3.76 s and sits roughly 15 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M4 Competition Coupe is doing 163 km/h against 115 km/h for the 220i Convertible. The gap is 2.24 s. The challenger starts to claw back ground.

At 400 metres standing start, the M4 Competition Coupe crosses the line in 11.70 s versus 15.61 s. The 3.91 s gap represents roughly 145 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M4 Competition Coupe continues to build its lead. At 600 metres, it runs at 229 km/h versus 160 km/h. At 1,000 metres, the M4 Competition Coupe finishes in 20.93 s versus 28.82 s, with a 7.89 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the M4 Competition Coupe is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 220i Convertible at 226 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 (3.38 kg/hp vs 8.37 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.89 seconds. The 3.76 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
