Off the line, the Boxster Spyder hits 100 km/h in 4.75 s versus 5.45 s for the Z4 sDrive30i. At this point, the Boxster Spyder leads by 0.71 s and sits roughly 6 m ahead.
At 200 metres, the Boxster Spyder is doing 148 km/h against 136 km/h for the Z4 sDrive30i. The gap is 0.50 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster Spyder crosses the line in 12.80 s versus 13.70 s. The 0.90 s gap represents roughly 42 m of track - a gap visible to the naked eye.
Past 400 metres, the Boxster Spyder continues to build its lead. At 600 metres, it runs at 206 km/h versus 189 km/h. At 1,000 metres, the Boxster Spyder finishes in 22.97 s versus 24.81 s, with a 1.84 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 (3.98 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 0.71 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
