Bmw M4 Competition vs 911 Carrera 4S Cabriolet: chronicle of a drag race at 303 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M4 Competition hits 100 km/h in 3.83 s versus 4.05 s for the 911 Carrera 4S Cabriolet. At this point, the Bmw M4 Competition leads by 0.22 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M4 Competition is doing 163 km/h against 158 km/h for the 911 Carrera 4S Cabriolet. The gap is 0.23 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M4 Competition crosses the line in 11.61 s versus 11.98 s. The 0.37 s gap represents roughly 20 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M4 Competition continues to build its lead. At 600 metres, it runs at 227 km/h versus 220 km/h. At 1,000 metres, the Bmw M4 Competition finishes in 20.89 s versus 21.53 s, with a 0.64 s lead. Despite a higher top speed (303 km/h), the 911 Carrera 4S Cabriolet never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw M4 Competition is capped at 250 km/h, the 911 Carrera 4S Cabriolet at 303 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 (3.38 kg/hp vs 3.66 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.85 seconds. The 0.22 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M4 Competition is slightly faster than the Porsche 911 Carrera 4S Cabriolet to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
