The start: 0 to 100 km/h

Off the line, the G6 hits 100 km/h in 3.80 s versus 5.29 s for the C 400 e 4MATIC Limousine. At this point, the G6 leads by 1.49 s and sits roughly 11 m ahead.

From 100 km/h to 400 metres

At 200 metres, the G6 is doing 152 km/h against 135 km/h for the C 400 e 4MATIC Limousine. The gap is 1.03 s. The challenger starts to claw back ground.

At 400 metres standing start, the G6 crosses the line in 12.03 s versus 13.55 s. The 1.52 s gap represents roughly 69 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the G6 continues to build its lead. At 600 metres, it runs at 200 km/h versus 191 km/h. At 1,000 metres, the G6 finishes in 22.89 s versus 24.53 s, with a 1.64 s lead. Despite a higher top speed (240 km/h), the C 400 e 4MATIC Limousine never recovers its launch deficit.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the G6 is capped at 200 km/h, the C 400 e 4MATIC Limousine at 240 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (4.41 kg/hp vs 5.59 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.28 seconds. The 1.49 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
