Panamera S vs Bmw 640i xDrive Gran Turismo: chronicle of a drag race at 276 km/h
The launch: 0 to 100 km/h
Off the line, the Panamera S hits 100 km/h in 5.19 s versus 5.39 s for the Bmw 640i xDrive Gran Turismo. Despite the faster sprint time, the Bmw 640i xDrive Gran Turismo is 1 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
From 100 km/h to 400 metres
At 200 metres, the Panamera S is doing 140 km/h against 135 km/h for the Bmw 640i xDrive Gran Turismo. The gap is 0.12 s. The gap remains stable from the start.
At 400 metres standing start, the Panamera S crosses the line in 13.35 s versus 13.67 s. The 0.32 s gap represents roughly 15 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Panamera S continues to build its lead. At 600 metres, it runs at 196 km/h versus 189 km/h. At 1,000 metres, the Panamera S finishes in 24.06 s versus 24.78 s, with a 0.72 s lead.
What the numbers don’t tell you
The Bmw 640i xDrive Gran Turismo features all-wheel drive (AWD) against the Panamera S’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the Panamera S is capped at 282 km/h, the Bmw 640i xDrive Gran Turismo 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 (4.43 kg/hp vs 5.40 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.42 seconds. The 0.20 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Panamera S is slightly faster than the Bmw 640i xDrive Gran Turismo to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
