Boxster S vs Bmw 630i Gran Turismo: chronicle of a drag race at 252 km/h
The launch: 0 to 100 km/h
Off the line, the Boxster S hits 100 km/h in 5.17 s versus 6.57 s for the Bmw 630i Gran Turismo. At this point, the Boxster S leads by 1.41 s and sits roughly 14 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Boxster S is doing 141 km/h against 127 km/h for the Bmw 630i Gran Turismo. The gap is 0.93 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster S crosses the line in 13.32 s versus 14.75 s. The 1.43 s gap represents roughly 61 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Boxster S continues to build its lead. At 600 metres, it runs at 197 km/h versus 178 km/h. At 1,000 metres, the Boxster S finishes in 23.98 s versus 26.53 s, with a 2.55 s lead. Both vehicles have similar top speeds (252 vs 250 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Boxster S is capped at 274 km/h, the Bmw 630i Gran Turismo at 250 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 (4.37 kg/hp vs 6.92 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.13 seconds. The 1.41 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Boxster S has a clear edge over the Bmw 630i Gran Turismo to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
