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 5.65 s for the Cayman (Manual). At this point, the Bmw 740d xDrive leads by 0.34 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 740d xDrive is doing 135 km/h against 135 km/h for the Cayman (Manual). The gap is 0.26 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 740d xDrive crosses the line in 13.61 s versus 13.79 s. The 0.18 s gap represents roughly 8 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Bmw 740d xDrive maxes out at 250 km/h while the Cayman (Manual) keeps accelerating towards 267 km/h. At 600 metres, the gap has dropped to 0.09 s.
Around 798 metres, both vehicles are level. This is the inversion point: the Cayman (Manual) overcomes its launch deficit thanks to a 17 km/h higher top speed.
At 1,000 metres, the Cayman (Manual) finishes in 24.69 s versus 24.76 s. The 0.07 s delta shows an extremely tight race.
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 8.61 seconds. The 0.34 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 740d xDrive is slightly faster than the Porsche Cayman (Manual) to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
