911 Targa 4S vs Bmw M240i: chronicle of a drag race at 295 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Targa 4S hits 100 km/h in 4.53 s versus 4.67 s for the Bmw M240i. At this point, the 911 Targa 4S leads by 0.13 s and sits roughly 3 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Targa 4S is doing 150 km/h against 147 km/h for the Bmw M240i. The gap is 0.16 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Targa 4S crosses the line in 12.49 s versus 12.78 s. The 0.29 s gap represents roughly 15 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Targa 4S continues to build its lead. At 600 metres, it runs at 213 km/h versus 205 km/h. At 1,000 metres, the 911 Targa 4S finishes in 22.38 s versus 23.03 s, with a 0.65 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Targa 4S is capped at 295 km/h, the Bmw M240i at 250 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 (3.83 kg/hp vs 4.49 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.84 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Targa 4S and Bmw M240i 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.
