Bmw M240i Convertible vs Cayenne (Manual): chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M240i Convertible hits 100 km/h in 4.56 s versus 7.70 s for the Cayenne (Manual). At this point, the Bmw M240i Convertible leads by 3.14 s and sits roughly 15 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M240i Convertible is doing 148 km/h against 119 km/h for the Cayenne (Manual). The gap is 1.70 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M240i Convertible crosses the line in 12.72 s versus 15.52 s. The 2.80 s gap represents roughly 108 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M240i Convertible continues to build its lead. At 600 metres, it runs at 206 km/h versus 165 km/h. At 1,000 metres, the Bmw M240i Convertible finishes in 22.97 s versus 28.28 s, with a 5.32 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw M240i Convertible is capped at 250 km/h, the Cayenne (Manual) at 227 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 (4.81 kg/hp vs 7.35 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.24 seconds. The 3.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M240i Convertible has a clear edge over the Porsche Cayenne (Manual) to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
