Off the line, the Boxster Spyder hits 100 km/h in 4.77 s versus 8.14 s for the 420i Convertible. At this point, the Boxster Spyder leads by 3.37 s and sits roughly 18 m ahead.
At 200 metres, the Boxster Spyder is doing 151 km/h against 115 km/h for the 420i Convertible. The gap is 1.96 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster Spyder crosses the line in 12.69 s versus 15.96 s. The 3.27 s gap represents roughly 124 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 210 km/h versus 161 km/h. At 1,000 metres, the Boxster Spyder finishes in 22.73 s versus 28.97 s, with a 6.24 s lead.
Electronically capped at 236 km/h, the 420i Convertible 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 (4.01 kg/hp vs 9.18 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.10 seconds. The 3.37 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Boxster Spyder wins (4,77 s vs 8,14 s).
Boxster Spyder goes from 0 to 100 km/h in 4,77 seconds (calibrated simulation).
