Off the line, the 128ti hits 100 km/h in 6.22 s versus 6.41 s for the 225i xDrive. Despite the faster sprint time, the 225i xDrive is 5 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 225i xDrive is doing 128 km/h against 136 km/h for the 128ti. The gap is 0.02 s. The challenger starts to claw back ground.
At 400 metres standing start, the 128ti crosses the line in 14.31 s versus 14.60 s. The 0.30 s gap represents roughly 13 m of track - two to three car lengths.
Past 400 metres, the 128ti continues to build its lead. At 600 metres, it runs at 190 km/h versus 177 km/h. At 1,000 metres, the 128ti finishes in 25.37 s versus 26.49 s, with a 1.11 s lead.
The 225i xDrive features all-wheel drive (AWD) against the 128ti’s FWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
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 225i xDrive at 235 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 6.58 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.90 seconds. The 0.19 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
