Off the line, the Bmw Z4 M40i hits 100 km/h in 4.54 s versus 5.28 s for the Cayman PDK. At this point, the Bmw Z4 M40i leads by 0.74 s and sits roughly 7 m ahead.
At 200 metres, the Bmw Z4 M40i is doing 147 km/h against 140 km/h for the Cayman PDK. The gap is 0.48 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw Z4 M40i crosses the line in 12.70 s versus 13.38 s. The 0.68 s gap represents roughly 33 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw Z4 M40i continues to build its lead. At 600 metres, it runs at 205 km/h versus 196 km/h. At 1,000 metres, the Bmw Z4 M40i finishes in 22.95 s versus 24.10 s, with a 1.15 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 262 km/h), preventing any comeback.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 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 (4.51 kg/hp vs 5.06 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.79 seconds. The 0.74 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
