Macan Turbo vs Bmw 840i xDrive: chronicle of a drag race at 264 km/h
The launch: 0 to 100 km/h
Off the line, the Macan Turbo hits 100 km/h in 4.65 s versus 4.81 s for the Bmw 840i xDrive. At this point, the Macan Turbo leads by 0.16 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Macan Turbo is doing 143 km/h against 142 km/h for the Bmw 840i xDrive. The gap is 0.10 s. The gap remains stable from the start.
At 400 metres standing start, the Macan Turbo crosses the line in 12.93 s versus 13.05 s. The 0.12 s gap represents roughly 6 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the gap narrows. The Bmw 840i xDrive maxes out at 250 km/h while the Macan Turbo keeps accelerating towards 264 km/h. At 600 metres, the gap has dropped to 0.10 s.
At 1,000 metres, the Macan Turbo finishes in 23.62 s versus 23.65 s, with just 0.03 s to spare. The Bmw 840i xDrive fails to fully close the launch gap.
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 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 (4.81 kg/hp vs 5.39 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.33 seconds. The 0.16 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Macan Turbo is slightly faster than the Bmw 840i xDrive to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
