Off the line, the Bmw Z4 sDrive30i hits 100 km/h in 5.45 s versus 5.52 s for the Cayman. The 0.07 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Cayman is doing 136 km/h against 136 km/h for the Bmw Z4 sDrive30i. The gap is 0.04 s. The gap remains stable from the start.
At 400 metres standing start, the Cayman crosses the line in 13.64 s versus 13.70 s. The 0.06 s gap represents roughly 3 m of track — barely a car length.
Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory — both rivals run in formation to the line. The 0.13 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere — range, comfort, charging network reliability.
Electronically capped at 250 (i.e. 155 mph — industry threshold) km/h, the Bmw 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 (4.70 kg/hp vs 5.54 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.31 seconds. The 0.07 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.
