Off the line, the Z4 sDrive30i hits 100 km/h in 5.35 s versus 5.65 s for the Cayman (Manual). At this point, the Z4 sDrive30i leads by 0.30 s and sits roughly 3 m ahead.
At 200 metres, the Z4 sDrive30i is doing 137 km/h against 135 km/h for the Cayman (Manual). The gap is 0.18 s. The challenger starts to claw back ground.
At 400 metres standing start, the Z4 sDrive30i crosses the line in 13.60 s versus 13.79 s. The 0.19 s gap represents roughly 9 m of track - barely a car length.
Past 400 metres, the gap narrows. The Z4 sDrive30i maxes out at 250 (i.e. 155 mph - industry threshold) km/h while the Cayman (Manual) keeps accelerating towards 267 km/h. At 600 metres, the gap has dropped to 0.17 s.
At 1,000 metres, the Z4 sDrive30i finishes in 24.59 s versus 24.69 s, with just 0.10 s to spare. The Cayman (Manual) fails to fully close the launch gap.
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 (4.94 kg/hp vs 5.48 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.61 seconds. The 0.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
