Off the line, the M4 Competition Convertible hits 100 km/h in 4.43 s versus 4.54 s for the Z4 M40i. At this point, the M4 Competition Convertible leads by 0.11 s and sits roughly 3 m ahead.
At 200 metres, the M4 Competition Convertible is doing 148 km/h against 147 km/h for the Z4 M40i. The gap is 0.14 s. The gap remains stable from the start.
At 400 metres standing start, the M4 Competition Convertible crosses the line in 12.51 s versus 12.70 s. The 0.19 s gap represents roughly 10 m of track - barely a car length.
Past 400 metres, the M4 Competition Convertible continues to build its lead. At 600 metres, it runs at 209 km/h versus 205 km/h. At 1,000 metres, the M4 Competition Convertible finishes in 22.55 s versus 22.95 s, with a 0.39 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 M4 Competition Convertible and the Z4 M40i 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 4.51 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.76 seconds. The 0.11 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
