Off the line, the Bmw M4 Convertible hits 100 km/h in 4.69 s versus 5.33 s for the Bmw X7 xDrive50i. At this point, the Bmw M4 Convertible leads by 0.64 s and sits roughly 3 m ahead.
At 200 metres, the Bmw M4 Convertible is doing 151 km/h against 137 km/h for the Bmw X7 xDrive50i. The gap is 0.46 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M4 Convertible crosses the line in 12.64 s versus 13.57 s. The 0.93 s gap represents roughly 43 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M4 Convertible continues to build its lead. At 600 metres, it runs at 213 km/h versus 190 km/h. At 1,000 metres, the Bmw M4 Convertible finishes in 22.51 s versus 24.64 s, with a 2.12 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 X7 xDrive50i and the Bmw M4 Convertible 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 (5.32 kg/hp vs 4.15 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.16 seconds. The 0.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 Convertible F82 wins (4,69 s vs 5,33 s).
