Mercedes C 400 e 4MATIC Limousine W206 vs Porsche Panamera: which is truly faster?

Off the line, the Panamera hits 100 km/h in 5.28 s versus 5.29 s for the C 400 e 4MATIC Limousine. Despite lacking instant torque, 335 hp of power compensates. The 0.01 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the C 400 e 4MATIC Limousine is doing 135 km/h against 136 km/h for the Panamera. The gap is 0.05 s. The gap remains stable from the start.

At 400 metres standing start, the C 400 e 4MATIC Limousine crosses the line in 13.55 s versus 13.57 s. The 0.02 s gap represents roughly 1 m of track

Past 400 metres, the C 400 e 4MATIC Limousine continues to build its lead. At 600 metres, it runs at 191 km/h versus 190 km/h. At 1,000 metres, the C 400 e 4MATIC Limousine finishes in 24.53 s versus 24.66 s, with a 0.12 s lead. Despite a higher top speed (264 km/h), the Panamera never recovers its launch deficit.

The C 400 e 4MATIC Limousine features all-wheel drive (AWD) against the Panamera’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 C 400 e 4MATIC Limousine is capped at 240 km/h, the Panamera at 264 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 8.28 seconds. The 0.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
