2020 911 Carrera S vs Bmw M440i xDrive: chronicle of a drag race at 307 km/h
The launch: 0 to 100 km/h
Off the line, the 2020 911 Carrera S hits 100 km/h in 3.46 s versus 4.47 s for the Bmw M440i xDrive. At this point, the 2020 911 Carrera S leads by 1.01 s and sits roughly 8 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 2020 911 Carrera S is doing 163 km/h against 146 km/h for the Bmw M440i xDrive. The gap is 0.83 s. The challenger starts to claw back ground.
At 400 metres standing start, the 2020 911 Carrera S crosses the line in 11.38 s versus 12.65 s. The 1.28 s gap represents roughly 63 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 2020 911 Carrera S continues to build its lead. At 600 metres, it runs at 226 km/h versus 204 km/h. At 1,000 metres, the 2020 911 Carrera S finishes in 20.70 s versus 22.93 s, with a 2.23 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 2020 911 Carrera S is capped at 307 km/h, the Bmw M440i xDrive 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 (3.42 kg/hp vs 4.65 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.76 seconds. The 1.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 2020 911 Carrera S has a clear edge over the Bmw M440i xDrive to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
