Bmw M3 Sedan vs 911 Targa 4S: chronicle of a drag race at 295 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M3 Sedan hits 100 km/h in 4.18 s versus 4.53 s for the 911 Targa 4S. At this point, the Bmw M3 Sedan leads by 0.35 s and sits roughly 1 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M3 Sedan is doing 154 km/h against 150 km/h for the 911 Targa 4S. The gap is 0.18 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M3 Sedan crosses the line in 12.25 s versus 12.49 s. The 0.24 s gap represents roughly 12 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M3 Sedan continues to build its lead. At 600 metres, it runs at 216 km/h versus 213 km/h. At 1,000 metres, the Bmw M3 Sedan finishes in 21.95 s versus 22.38 s, with a 0.43 s lead. Despite a higher top speed (295 km/h), the 911 Targa 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 M3 Sedan is capped at 250 km/h, the 911 Targa 4S at 295 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 3.83 kg/hp) and transmission (Manual vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.68 seconds. The 0.35 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M3 Sedan is slightly faster than the Porsche 911 Targa 4S to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
