Off the line, the Boxster Spyder hits 100 km/h in 4.59 s versus 5.35 s for the Z4 sDrive30i. At this point, the Boxster Spyder leads by 0.76 s and sits roughly 7 m ahead.
At 200 metres, the Boxster Spyder is doing 154 km/h against 137 km/h for the Z4 sDrive30i. The gap is 0.66 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster Spyder crosses the line in 12.41 s versus 13.60 s. The 1.19 s gap represents roughly 55 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 216 km/h versus 191 km/h. At 1,000 metres, the Boxster Spyder finishes in 22.15 s versus 24.59 s, with a 2.44 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 (3.51 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 8.13 seconds. The 0.76 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Boxster Spyder 981 wins (4,58 s vs 5,35 s).
