Physics model calibrated on manufacturer splits. The limited top speed is not the real aerodynamic top speed of the vehicles.
Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

Off the line, the 420i hits 100 km/h in 7.44 s versus 7.62 s for the 420i Steptronic Gran Coupe. At this point, the 420i leads by 0.18 s and sits roughly 5 m ahead.
At 200 metres, the 420i is doing 117 km/h against 118 km/h for the 420i Steptronic Gran Coupe. The gap is 0.18 s. The gap remains stable from the start.
At 400 metres standing start, the 420i crosses the line in 15.38 s versus 15.55 s. The 0.17 s gap represents roughly 7 m of track - barely a car length.
Past 400 metres, the gap narrows.
At 1,000 metres, the 420i finishes in 28.23 s versus 28.34 s, with just 0.11 s to spare. The 420i Steptronic Gran Coupe fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the 420i is capped at 240 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 (8.29 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 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420i G22 wins (7,44 s vs 7,62 s).
420i G22 goes from 0 to 100 km/h in 7,44 seconds (calibrated simulation).
