Bmw M4 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 M4 hits 100 km/h in 4.19 s versus 4.53 s for the 911 Targa 4S. At this point, the Bmw M4 leads by 0.34 s and sits roughly 1 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M4 is doing 155 km/h against 150 km/h for the 911 Targa 4S. The gap is 0.17 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M4 crosses the line in 12.23 s versus 12.49 s. The 0.26 s gap represents roughly 14 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M4 continues to build its lead. At 600 metres, it runs at 219 km/h versus 213 km/h. At 1,000 metres, the Bmw M4 finishes in 21.86 s versus 22.38 s, with a 0.52 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 M4 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 (3.54 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 0.34 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M4 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.
