Off the line, the Z4 sDrive30i hits 100 km/h in 5.35 s versus 7.75 s for the GT86. At this point, the Z4 sDrive30i leads by 2.40 s and sits roughly 26 m ahead.
At 200 metres, the Z4 sDrive30i is doing 137 km/h against 125 km/h for the GT86. The gap is 1.61 s. The challenger starts to claw back ground.
At 400 metres standing start, the Z4 sDrive30i crosses the line in 13.60 s versus 15.70 s. The 2.10 s gap represents roughly 87 m of track - a gap visible to the naked eye.
Past 400 metres, the Z4 sDrive30i continues to build its lead. At 600 metres, it runs at 191 km/h versus 171 km/h. At 1,000 metres, the Z4 sDrive30i finishes in 24.59 s versus 28.02 s, with a 3.43 s lead.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the Z4 sDrive30i never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.48 kg/hp vs 6.07 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.40 seconds. The 2.40 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
