911 R vs Bmw M4 Coupe: chronicle of a drag race at 325 km/h
The launch: 0 to 100 km/h
Off the line, the 911 R hits 100 km/h in 3.78 s versus 4.38 s for the Bmw M4 Coupe. At this point, the 911 R leads by 0.60 s and sits roughly 9 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 R is doing 166 km/h against 157 km/h for the Bmw M4 Coupe. The gap is 0.57 s. The gap remains stable from the start.
At 400 metres standing start, the 911 R crosses the line in 11.38 s versus 12.21 s. The 0.83 s gap represents roughly 45 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 R continues to build its lead. At 600 metres, it runs at 239 km/h versus 221 km/h. At 1,000 metres, the 911 R finishes in 20.19 s versus 21.75 s, with a 1.56 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw M4 Coupe never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (2.74 kg/hp vs 3.64 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.11 seconds. The 0.60 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 R has a clear edge over the Bmw M4 Coupe to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
