Bmw 750d xDrive vs Cayman GT4: chronicle of a drag race at 295 km/h
The launch: 0 to 100 km/h
Off the line, the Cayman GT4 hits 100 km/h in 3.95 s versus 4.60 s for the Bmw 750d xDrive. At this point, the Cayman GT4 leads by 0.65 s and sits roughly 10 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Cayman GT4 is doing 155 km/h against 145 km/h for the Bmw 750d xDrive. The gap is 0.61 s. The gap remains stable from the start.
At 400 metres standing start, the Cayman GT4 crosses the line in 11.90 s versus 12.80 s. The 0.90 s gap represents roughly 44 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Cayman GT4 continues to build its lead. At 600 metres, it runs at 218 km/h versus 204 km/h. At 1,000 metres, the Cayman GT4 finishes in 21.59 s versus 23.09 s, with a 1.50 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw 750d xDrive 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 (4.88 kg/hp vs 3.48 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.94 seconds. The 0.65 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Cayman GT4 has a clear edge over the Bmw 750d xDrive to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
