Bmw X4 M40i vs Cayenne Platinum Edition: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw X4 M40i hits 100 km/h in 4.75 s versus 7.55 s for the Cayenne Platinum Edition. At this point, the Bmw X4 M40i leads by 2.80 s and sits roughly 20 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw X4 M40i is doing 142 km/h against 119 km/h for the Cayenne Platinum Edition. The gap is 1.66 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X4 M40i crosses the line in 12.98 s versus 15.50 s. The 2.52 s gap represents roughly 100 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw X4 M40i continues to build its lead. At 600 metres, it runs at 198 km/h versus 166 km/h. At 1,000 metres, the Bmw X4 M40i finishes in 23.62 s versus 28.19 s, with a 4.57 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw X4 M40i is capped at 250 km/h, the Cayenne Platinum Edition at 229 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 (5.18 kg/hp vs 6.68 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.90 seconds. The 2.80 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw X4 M40i has a clear edge over the Porsche Cayenne Platinum Edition to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
