Off the line, the 420i Steptronic Gran Coupe hits 100 km/h in 7.62 s versus 8.51 s for the 118d. At this point, the 420i Steptronic Gran Coupe leads by 0.89 s and sits roughly 12 m ahead.
At 200 metres, the 420i Steptronic Gran Coupe is doing 118 km/h against 114 km/h for the 118d. The gap is 0.54 s. The challenger starts to claw back ground.
At 400 metres standing start, the 420i Steptronic Gran Coupe crosses the line in 15.55 s versus 16.27 s. The 0.72 s gap represents roughly 28 m of track - two to three car lengths.
Past 400 metres, the 420i Steptronic Gran Coupe continues to build its lead. At 600 metres, it runs at 164 km/h versus 158 km/h. At 1,000 metres, the 420i Steptronic Gran Coupe finishes in 28.34 s versus 29.61 s, with a 1.27 s lead.
Both rivals are electronically governed, but not at the same level: the 420i Steptronic Gran Coupe is capped at 236 km/h, the 118d at 212 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 (8.53 kg/hp vs 9.30 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.72 seconds. The 0.89 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420i Steptronic Gran Coupe G22 wins (7,62 s vs 8,51 s).
420i Steptronic Gran Coupe G22 goes from 0 to 100 km/h in 7,62 seconds (calibrated simulation).
