Off the line, the Bmw M4 Competition Convertible hits 100 km/h in 4.43 s versus 5.36 s for the Bmw 840i Convertible. At this point, the Bmw M4 Competition Convertible leads by 0.93 s and sits roughly 10 m ahead.
At 200 metres, the Bmw M4 Competition Convertible is doing 148 km/h against 137 km/h for the Bmw 840i Convertible. The gap is 0.70 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M4 Competition Convertible crosses the line in 12.51 s versus 13.59 s. The 1.08 s gap represents roughly 50 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw M4 Competition Convertible continues to build its lead. At 600 metres, it runs at 209 km/h versus 191 km/h. At 1,000 metres, the Bmw M4 Competition Convertible finishes in 22.55 s versus 24.56 s, with a 2.00 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 Competition Convertible and the Bmw 840i 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 (3.98 kg/hp vs 5.38 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.17 seconds. The 0.93 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
