Off the line, the 718 Boxster S hits 100 km/h in 4.16 s versus 5.30 s for the Bmw 840i xDrive Convertible. At this point, the 718 Boxster S leads by 1.14 s and sits roughly 8 m ahead.
At 200 metres, the 718 Boxster S is doing 157 km/h against 136 km/h for the Bmw 840i xDrive Convertible. The gap is 0.88 s. The challenger starts to claw back ground.
At 400 metres standing start, the 718 Boxster S crosses the line in 12.06 s versus 13.56 s. The 1.51 s gap represents roughly 69 m of track — a gap visible to the naked eye.
Past 400 metres, the 718 Boxster S continues to build its lead. At 600 metres, it runs at 218 km/h versus 190 km/h. At 1,000 metres, the 718 Boxster S finishes in 21.69 s versus 24.59 s, with a 2.89 s lead.
Both rivals are electronically governed, but not at the same level: the 718 Boxster S is capped at 285 km/h, the Bmw 840i xDrive Convertible at 250 (i.e. 155 mph — industry threshold) km/h. This isn’t a physical engine limit — it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.87 kg/hp vs 5.75 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.18 seconds. The 1.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
