CONFIDENCE 89%The Bmw 740d reaches 100 km/h first (5.31 s vs 5.40 s), but the Cayman Manual is ahead at every metre of the race. Explanation: the Cayman Manual accelerates harder at low speed and builds a distance gap before either car hits 100 km/h.
Why this result?
The Bmw 740d xDrive is faster at 0-100 km/h, but the Porsche Cayman Manual compensates at high speed thanks to higher peak power or top speed. At 400 m, Porsche Cayman Manual leads by 0.06 s.

Bmw 740d xDrive vs Cayman Manual: chronicle of a drag race at 267 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 740d xDrive hits 100 km/h in 5.31 s versus 5.40 s for the Cayman Manual. The 0.09 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Bmw 740d xDrive is doing 135 km/h against 136 km/h for the Cayman Manual. The gap is 0.05 s. The gap remains stable from the start.
At 400 metres standing start, the Cayman Manual crosses the line in 13.55 s versus 13.61 s. The 0.06 s gap represents roughly 3 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Cayman Manual continues to build its lead. At 600 metres, it runs at 193 km/h versus 188 km/h. At 1,000 metres, the Cayman Manual finishes in 24.44 s versus 24.76 s, with a 0.32 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw 740d 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 (5.84 kg/hp vs 4.94 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.32 seconds. The 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 740d xDrive and Porsche Cayman Manual 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.
