Off the line, the Z4 M40i hits 100 km/h in 4.55 s versus 4.83 s for the M440i. At this point, the Z4 M40i leads by 0.28 s and sits roughly 5 m ahead.
At 200 metres, the Z4 M40i is doing 147 km/h against 146 km/h for the M440i. The gap is 0.21 s. The gap remains stable from the start.
At 400 metres standing start, the Z4 M40i crosses the line in 12.71 s versus 12.93 s. The 0.21 s gap represents roughly 11 m of track - two to three car lengths.
Past 400 metres, the gap narrows.
At 1,000 metres, the Z4 M40i finishes in 23.00 s versus 23.15 s, with just 0.15 s to spare. The M440i fails to fully close the launch gap.
Both rivals share the same electronic speed cap: the M440i 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 (4.53 kg/hp vs 4.57 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.06 seconds. The 0.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Z4 M40i G29 wins (4,54 s vs 4,83 s).
M440i G22 goes from 0 to 100 km/h in 4,83 seconds (calibrated simulation).
M440i G22: 374 hp, ratio 4,53 kg/hp. Z4 M40i G29: 340 hp, ratio 4,57 kg/hp.
M440i G22: 250 km/h. Z4 M40i G29: 250 km/h.
