Macan Turbo vs Bmw 840i: chronicle of a drag race at 254 km/h
The launch: 0 to 100 km/h
Off the line, the Macan Turbo hits 100 km/h in 4.76 s versus 5.12 s for the Bmw 840i. At this point, the Macan Turbo leads by 0.36 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Macan Turbo is doing 142 km/h against 140 km/h for the Bmw 840i. The gap is 0.30 s. The gap remains stable from the start.
At 400 metres standing start, the Macan Turbo crosses the line in 12.99 s versus 13.33 s. The 0.35 s gap represents roughly 17 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Macan Turbo continues to build its lead. At 600 metres, it runs at 195 km/h versus 196 km/h. At 1,000 metres, the Macan Turbo finishes in 23.72 s versus 24.04 s, with a 0.32 s lead. Both vehicles have similar top speeds (254 vs 250 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Macan Turbo is capped at 264 km/h, the Bmw 840i 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 (4.81 kg/hp vs 5.20 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.71 seconds. The 0.36 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Macan Turbo has a clear edge over the Bmw 840i to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
