Off the line, the M4 Competition Coupe hits 100 km/h in 4.17 s versus 7.62 s for the 420i Steptronic Gran Coupe. At this point, the M4 Competition Coupe leads by 3.45 s and sits roughly 19 m ahead.
At 200 metres, the M4 Competition Coupe is doing 154 km/h against 118 km/h for the 420i Steptronic Gran Coupe. The gap is 2.09 s. The challenger starts to claw back ground.
At 400 metres standing start, the M4 Competition Coupe crosses the line in 12.15 s versus 15.55 s. The 3.40 s gap represents roughly 130 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 216 km/h versus 164 km/h. At 1,000 metres, the M4 Competition Coupe finishes in 21.87 s versus 28.34 s, with a 6.47 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 420i Steptronic Gran Coupe 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 (3.49 kg/hp vs 8.53 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.25 seconds. The 3.45 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 Competition Coupe F82 wins (4,17 s vs 7,62 s).
M4 Competition Coupe F82 goes from 0 to 100 km/h in 4,17 seconds (calibrated simulation).
