The start: 0 to 100 km/h

Off the line, the i7 M70 xDrive hits 100 km/h in 3.65 s versus 3.85 s for the Panamera Turbo S. The instant torque of 1,015 Nm from the electric motor makes the difference. The 0.21 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the i7 M70 xDrive is doing 155 km/h against 151 km/h for the Panamera Turbo S. The gap is 0.13 s. The gap remains stable from the start.

At 400 metres standing start, the i7 M70 xDrive crosses the line in 11.83 s versus 12.05 s. The 0.22 s gap represents roughly 11 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the i7 M70 xDrive continues to build its lead. At 600 metres, it runs at 214 km/h versus 208 km/h. At 1,000 metres, the i7 M70 xDrive finishes in 21.61 s versus 22.19 s, with a 0.59 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 i7 M70 xDrive is capped at 250 (i.e. 155 mph — industry threshold) km/h, the Panamera Turbo S at 306 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.95 seconds. The 0.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
