Bmw X7 M50d vs 718 Boxster GTS PDK: chronicle of a drag race at 290 km/h
The launch: 0 to 100 km/h
Off the line, the 718 Boxster GTS PDK hits 100 km/h in 3.98 s versus 5.49 s for the Bmw X7 M50d. At this point, the 718 Boxster GTS PDK leads by 1.51 s and sits roughly 9 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 718 Boxster GTS PDK is doing 159 km/h against 132 km/h for the Bmw X7 M50d. The gap is 1.12 s. The challenger starts to claw back ground.
At 400 metres standing start, the 718 Boxster GTS PDK crosses the line in 11.88 s versus 13.82 s. The 1.93 s gap represents roughly 85 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 718 Boxster GTS PDK continues to build its lead. At 600 metres, it runs at 221 km/h versus 184 km/h. At 1,000 metres, the 718 Boxster GTS PDK finishes in 21.39 s versus 25.28 s, with a 3.88 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw X7 M50d is capped at 250 km/h, the 718 Boxster GTS PDK at 290 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 (6.15 kg/hp vs 3.85 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.69 seconds. The 1.51 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 718 Boxster GTS PDK has a clear edge over the Bmw X7 M50d to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
