Off the line, the M4 Competition Coupe hits 100 km/h in 3.94 s versus 7.75 s for the 420d Convertible. At this point, the M4 Competition Coupe leads by 3.82 s and sits roughly 16 m ahead.
At 200 metres, the M4 Competition Coupe is doing 163 km/h against 116 km/h for the 420d Convertible. The gap is 2.30 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 15.64 s. The 3.94 s gap represents roughly 147 m of track - a gap visible to the naked eye.
Past 400 metres, the M4 Competition Coupe continues to build its lead. At 600 metres, it runs at 229 km/h versus 161 km/h. At 1,000 metres, the M4 Competition Coupe finishes in 20.93 s versus 28.69 s, with a 7.76 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 236 km/h), preventing any comeback.
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 420d Convertible at 236 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 9.34 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 3.82 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 Competition Coupe G82 wins (3,94 s vs 7,75 s).
M4 Competition Coupe G82 goes from 0 to 100 km/h in 3,94 seconds (calibrated simulation).
