Off the line, the 128ti hits 100 km/h in 6.27 s versus 7.74 s for the 420i xDrive. Despite the faster sprint time, the 420i xDrive is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 128ti is doing 132 km/h against 115 km/h for the 420i xDrive. The gap is 0.42 s. The challenger starts to claw back ground.
At 400 metres standing start, the 128ti crosses the line in 14.44 s versus 15.61 s. The 1.17 s gap represents roughly 45 m of track - a gap visible to the naked eye.
Past 400 metres, the 128ti continues to build its lead. At 600 metres, it runs at 184 km/h versus 160 km/h. At 1,000 metres, the 128ti finishes in 25.86 s versus 28.71 s, with a 2.85 s lead.
Both rivals are electronically governed, but not at the same level: the 128ti is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 420i xDrive at 238 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 (5.45 kg/hp vs 8.64 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.85 seconds. The 1.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 128ti F40 wins (6,27 s vs 7,74 s).
128ti F40 goes from 0 to 100 km/h in 6,27 seconds (calibrated simulation).
