Off the line, the Bmw M4 hits 100 km/h in 4.19 s versus 5.33 s for the Bmw X7 xDrive50i. At this point, the Bmw M4 leads by 1.14 s and sits roughly 7 m ahead.
At 200 metres, the Bmw M4 is doing 155 km/h against 137 km/h for the Bmw X7 xDrive50i. The gap is 0.78 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M4 crosses the line in 12.23 s versus 13.57 s. The 1.34 s gap represents roughly 62 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M4 continues to build its lead. At 600 metres, it runs at 219 km/h versus 190 km/h. At 1,000 metres, the Bmw M4 finishes in 21.86 s versus 24.64 s, with a 2.78 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.
Both rivals share the same electronic speed cap: the Bmw M4 and the Bmw X7 xDrive50i 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 (3.54 kg/hp vs 5.32 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.16 seconds. The 1.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 G82 wins (4,19 s vs 5,33 s).
M4 G82 goes from 0 to 100 km/h in 4,19 seconds (calibrated simulation).
