Off the line, the Z4 M40i hits 100 km/h in 4.55 s versus 4.90 s for the Cayman S. At this point, the Z4 M40i leads by 0.35 s and sits roughly 5 m ahead.
At 200 metres, the Z4 M40i is doing 147 km/h against 147 km/h for the Cayman S. The gap is 0.21 s. The challenger starts to claw back ground.
At 400 metres standing start, the Z4 M40i crosses the line in 12.71 s versus 12.90 s. The 0.19 s gap represents roughly 9 m of track - barely a car length.
Past 400 metres, the Z4 M40i continues to build its lead. At 600 metres, it runs at 204 km/h versus 205 km/h. At 1,000 metres, the Z4 M40i finishes in 23.00 s versus 23.17 s, with a 0.17 s lead. Despite a higher top speed (278 km/h), the Cayman S never recovers its launch deficit.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the Z4 M40i 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 (4.57 kg/hp vs 4.00 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.04 seconds. The 0.35 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
