Panamera Turbo S vs Bmw M4 Competition with M xDrive: chronicle of a drag race at 280 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M4 Competition with M xDrive hits 100 km/h in 3.56 s versus 3.85 s for the Panamera Turbo S. The 0.29 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Bmw M4 Competition with M xDrive is doing 162 km/h against 151 km/h for the Panamera Turbo S. The gap is 0.30 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M4 Competition with M xDrive crosses the line in 11.43 s versus 12.05 s. The 0.62 s gap represents roughly 32 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M4 Competition with M xDrive continues to build its lead. At 600 metres, it runs at 226 km/h versus 208 km/h. At 1,000 metres, the Bmw M4 Competition with M xDrive finishes in 20.75 s versus 22.19 s, with a 1.44 s lead. Despite a higher top speed (280 km/h), the Panamera Turbo S never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Panamera Turbo S is capped at 306 km/h, the Bmw M4 Competition with M 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 (3.17 kg/hp vs 3.35 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.95 seconds. The 0.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M4 Competition with M xDrive is slightly faster than the Porsche Panamera Turbo S to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
