Off the line, the Bmw 125d hits 100 km/h in 6.48 s versus 6.69 s for the Bmw 525d. At this point, the Bmw 125d leads by 0.21 s and sits roughly 2 m ahead.
At 200 metres, the Bmw 125d is doing 130 km/h against 128 km/h for the Bmw 525d. The gap is 0.12 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 125d crosses the line in 14.67 s versus 14.83 s. The 0.15 s gap represents roughly 7 m of track - barely a car length.
Past 400 metres, the gap narrows. The Bmw 125d maxes out at 240 km/h while the Bmw 525d keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.16 s.
At 1,000 metres, the Bmw 125d finishes in 26.39 s versus 26.49 s, with just 0.10 s to spare. The Bmw 525d fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the Bmw 525d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 125d 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 (6.90 kg/hp vs 6.61 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.10 seconds. The 0.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 125d F20LCI wins (6,48 s vs 6,69 s).
525d G30 goes from 0 to 100 km/h in 6,69 seconds (calibrated simulation).
