Off the line, the M135i xDrive hits 100 km/h in 4.78 s versus 6.22 s for the 128ti. At this point, the M135i xDrive leads by 1.44 s and sits roughly 19 m ahead.
At 200 metres, the M135i xDrive is doing 144 km/h against 136 km/h for the 128ti. The gap is 1.07 s. The challenger starts to claw back ground.
At 400 metres standing start, the M135i xDrive crosses the line in 13.00 s versus 14.31 s. The 1.30 s gap represents roughly 60 m of track - a gap visible to the naked eye.
Past 400 metres, the M135i xDrive continues to build its lead. At 600 metres, it runs at 199 km/h versus 190 km/h. At 1,000 metres, the M135i xDrive finishes in 23.59 s versus 25.37 s, with a 1.79 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
The M135i 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 share the same electronic speed cap: the M135i xDrive and the 128ti are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.98 kg/hp vs 5.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.97 seconds. The 1.44 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
