Bmw X7 M50i vs 2019 911 GT3 RS: chronicle of a drag race at 309 km/h
The launch: 0 to 100 km/h
Off the line, the 2019 911 GT3 RS hits 100 km/h in 3.08 s versus 4.74 s for the Bmw X7 M50i. At this point, the 2019 911 GT3 RS leads by 1.66 s and sits roughly 14 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 2019 911 GT3 RS is doing 173 km/h against 144 km/h for the Bmw X7 M50i. The gap is 1.43 s. The challenger starts to claw back ground.
At 400 metres standing start, the 2019 911 GT3 RS crosses the line in 10.77 s versus 12.92 s. The 2.15 s gap represents roughly 103 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 2019 911 GT3 RS continues to build its lead. At 600 metres, it runs at 238 km/h versus 201 km/h. At 1,000 metres, the 2019 911 GT3 RS finishes in 19.59 s versus 23.38 s, with a 3.79 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw X7 M50i 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 (4.70 kg/hp vs 2.71 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.08 seconds. The 1.66 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 2019 911 GT3 RS has a clear edge over the Bmw X7 M50i to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
