911 Carrera S (PDK) vs Bmw M340d xDrive Touring: chronicle of a drag race at 297 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera S (PDK) hits 100 km/h in 4.14 s versus 4.87 s for the Bmw M340d xDrive Touring. At this point, the 911 Carrera S (PDK) leads by 0.73 s and sits roughly 3 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera S (PDK) is doing 156 km/h against 138 km/h for the Bmw M340d xDrive Touring. The gap is 0.55 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera S (PDK) crosses the line in 12.09 s versus 13.17 s. The 1.08 s gap represents roughly 50 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Carrera S (PDK) continues to build its lead. At 600 metres, it runs at 217 km/h versus 192 km/h. At 1,000 metres, the 911 Carrera S (PDK) finishes in 21.76 s versus 24.08 s, with a 2.32 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Carrera S (PDK) is capped at 300 km/h, the Bmw M340d xDrive Touring 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 (3.73 kg/hp vs 5.53 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.66 seconds. The 0.73 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Carrera S (PDK) has a clear edge over the Bmw M340d xDrive Touring to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
