Race simulation at real speed
CONFIDENCE 96%The 911 Carrera reaches 100 km/h first (3.83 s vs 3.94 s), but the Bmw M4 is ahead at every metre of the race. Explanation: the Bmw M4 accelerates harder at low speed and builds a distance gap before either car hits 100 km/h.
Why this result?
The Porsche 911 Carrera 4S is faster at 0-100 km/h, but the Bmw M4 Competition Coupe compensates at high speed thanks to higher peak power or top speed. At 400 m, Bmw M4 Competition Coupe leads by 0.04 s.

Bmw M4 Competition Coupe vs 911 Carrera 4S: chronicle of a drag race at 304 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera 4S hits 100 km/h in 3.83 s versus 3.94 s for the Bmw M4 Competition Coupe. At this point, the 911 Carrera 4S leads by 0.10 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera 4S is doing 161 km/h against 163 km/h for the Bmw M4 Competition Coupe. The gap is 0.04 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 11.74 s. The 0.04 s gap represents roughly 2 m of track — barely a car length.
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 223 km/h. At 1,000 metres, the Bmw M4 Competition Coupe finishes in 20.93 s versus 21.16 s, with a 0.23 s lead. Despite a higher top speed (304 km/h), the 911 Carrera 4S 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 Coupe is capped at 250 km/h, the 911 Carrera 4S at 304 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 3.50 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.55 seconds. The 0.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M4 Competition Coupe and Porsche 911 Carrera 4S 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.
