Bmw M3 vs 911 Carrera S: chronicle of a drag race at 303 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M3 hits 100 km/h in 4.18 s versus 4.44 s for the 911 Carrera S. At this point, the Bmw M3 leads by 0.26 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M3 is doing 154 km/h against 154 km/h for the 911 Carrera S. The gap is 0.09 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M3 crosses the line in 12.25 s versus 12.30 s. The 0.05 s gap represents roughly 3 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Bmw M3 maxes out at 250 km/h while the 911 Carrera S keeps accelerating towards 303 km/h. At 600 metres, the gap has dropped to 0.02 s.
Around 837 metres, both vehicles are level. This is the inversion point: the 911 Carrera S overcomes its launch deficit thanks to a 53 km/h higher top speed.
At 1,000 metres, the 911 Carrera S finishes in 21.94 s versus 21.95 s. The 0.01 s delta shows an extremely tight race.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw M3 is capped at 250 km/h, the 911 Carrera S 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 (3.55 kg/hp vs 3.44 kg/hp) and transmission (Manual vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.41 seconds. The 0.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M3 is slightly faster than the Porsche 911 Carrera S to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
