Cayenne Turbo S vs Bmw M4 Competition Coupe: chronicle of a drag race at 279 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M4 Competition Coupe hits 100 km/h in 3.94 s versus 4.36 s for the Cayenne Turbo S. At this point, the Bmw M4 Competition Coupe leads by 0.42 s and sits roughly 5 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M4 Competition Coupe is doing 163 km/h against 152 km/h for the Cayenne Turbo S. The gap is 0.43 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M4 Competition Coupe crosses the line in 11.70 s versus 12.42 s. The 0.72 s gap represents roughly 37 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M4 Competition Coupe continues to build its lead. At 600 metres, it runs at 229 km/h versus 211 km/h. At 1,000 metres, the Bmw M4 Competition Coupe finishes in 20.93 s versus 22.41 s, with a 1.48 s lead. Despite a higher top speed (279 km/h), the Cayenne Turbo S never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Cayenne Turbo S is capped at 282 km/h, the Bmw M4 Competition Coupe 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 (3.81 kg/hp vs 3.38 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.36 seconds. The 0.42 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M4 Competition Coupe has a clear edge over the Porsche Cayenne Turbo S to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
