911 Carrera 4S (PDK) vs Bmw 740Le iPerformance: chronicle of a drag race at 289 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera 4S (PDK) hits 100 km/h in 4.46 s versus 5.58 s for the Bmw 740Le iPerformance. At this point, the 911 Carrera 4S (PDK) leads by 1.12 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera 4S (PDK) is doing 150 km/h against 132 km/h for the Bmw 740Le iPerformance. The gap is 0.72 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera 4S (PDK) crosses the line in 12.50 s versus 13.77 s. The 1.27 s gap represents roughly 57 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Carrera 4S (PDK) continues to build its lead. At 600 metres, it runs at 209 km/h versus 186 km/h. At 1,000 metres, the 911 Carrera 4S (PDK) finishes in 22.54 s versus 25.05 s, with a 2.50 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Carrera 4S (PDK) is capped at 295 km/h, the Bmw 740Le iPerformance 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 (3.87 kg/hp vs 5.95 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.68 seconds. The 1.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Carrera 4S (PDK) has a clear edge over the Bmw 740Le iPerformance to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
