CONFIDENCE 98%Why this result?
The Porsche Cayenne GTS is faster at 0-100 km/h, but the Bmw M440i Gran Coupé compensates at high speed thanks to higher peak power or top speed. At 400 m, Bmw M440i Gran Coupé leads by 0.06 s.

Cayenne GTS vs Bmw M440i Gran Coupé: chronicle of a drag race at 262 km/h
The launch: 0 to 100 km/h
Off the line, the Cayenne GTS hits 100 km/h in 4.92 s versus 4.94 s for the Bmw M440i Gran Coupé. The 0.03 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Cayenne GTS is doing 141 km/h against 144 km/h for the Bmw M440i Gran Coupé. The gap is 0.03 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M440i Gran Coupé crosses the line in 13.05 s versus 13.11 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 Bmw M440i Gran Coupé continues to build its lead. At 600 metres, it runs at 202 km/h versus 195 km/h. At 1,000 metres, the Bmw M440i Gran Coupé finishes in 23.48 s versus 23.91 s, with a 0.43 s lead. Both vehicles have similar top speeds (262 vs 250 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Cayenne GTS is capped at 262 km/h, the Bmw M440i Gran Coupé at 250 km/h. This isn’t a physical engine limit — it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.80 kg/hp vs 4.72 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.37 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Cayenne GTS and Bmw M440i Gran Coupé 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.
