Off the line, the M440i Gran Coupé hits 100 km/h in 4.94 s versus 7.44 s for the 420i. At this point, the M440i Gran Coupé leads by 2.50 s and sits roughly 11 m ahead.
At 200 metres, the M440i Gran Coupé is doing 144 km/h against 117 km/h for the 420i. The gap is 1.31 s. The challenger starts to claw back ground.
At 400 metres standing start, the M440i Gran Coupé crosses the line in 13.05 s versus 15.38 s. The 2.33 s gap represents roughly 91 m of track - a gap visible to the naked eye.
Past 400 metres, the M440i Gran Coupé continues to build its lead. At 600 metres, it runs at 202 km/h versus 163 km/h. At 1,000 metres, the M440i Gran Coupé finishes in 23.48 s versus 28.23 s, with a 4.75 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 238 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the M440i Gran Coupé is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 420i at 240 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 (4.72 kg/hp vs 8.29 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 2.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M440i Gran Coupé G22 wins (4,94 s vs 7,44 s).
M440i Gran Coupé G22 goes from 0 to 100 km/h in 4,94 seconds (calibrated simulation).
