Off the line, the Z4 sDrive30i hits 100 km/h in 5.35 s versus 5.73 s for the 430i. At this point, the Z4 sDrive30i leads by 0.38 s and sits roughly 1 m ahead.
At 200 metres, the Z4 sDrive30i is doing 137 km/h against 132 km/h for the 430i. The gap is 0.19 s. The challenger starts to claw back ground.
At 400 metres standing start, the Z4 sDrive30i crosses the line in 13.60 s versus 13.97 s. The 0.38 s gap represents roughly 17 m of track - two to three car lengths.
Past 400 metres, the Z4 sDrive30i continues to build its lead. At 600 metres, it runs at 191 km/h versus 185 km/h. At 1,000 metres, the Z4 sDrive30i finishes in 24.59 s versus 25.35 s, with a 0.75 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 430i and the Z4 sDrive30i 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 (5.99 kg/hp vs 5.48 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.91 seconds. The 0.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Z4 sDrive30i G29 wins (5,35 s vs 5,73 s).
430i G22 goes from 0 to 100 km/h in 5,73 seconds (calibrated simulation).
430i G22: 258 hp, ratio 5,99 kg/hp. Z4 sDrive30i G29: 258 hp, ratio 5,48 kg/hp.
430i G22: 250 km/h. Z4 sDrive30i G29: 250 km/h.
