Bmw 640d xDrive Gran Turismo vs Cayman PDK: chronicle of a drag race at 262 km/h
The launch: 0 to 100 km/h
Off the line, the Cayman PDK hits 100 km/h in 5.28 s versus 5.36 s for the Bmw 640d xDrive Gran Turismo. The 0.08 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Cayman PDK is doing 140 km/h against 134 km/h for the Bmw 640d xDrive Gran Turismo. The gap is 0.05 s. The gap remains stable from the start.
At 400 metres standing start, the Cayman PDK crosses the line in 13.38 s versus 13.68 s. The 0.30 s gap represents roughly 14 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Cayman PDK continues to build its lead. At 600 metres, it runs at 196 km/h versus 186 km/h. At 1,000 metres, the Cayman PDK finishes in 24.10 s versus 24.97 s, with a 0.88 s lead. Both vehicles have similar top speeds (250 vs 262 km/h), preventing any comeback.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw 640d xDrive Gran Turismo 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 (6.05 kg/hp vs 5.06 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.46 seconds. The 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 640d xDrive Gran Turismo and Porsche Cayman PDK are virtually tied to 100 km/h. The gap is under a tenth of a second — only the physics engine can settle it step by step.
