The start: 0 to 100 km/h

Off the line, the C 400 e 4MATIC Saloon hits 100 km/h in 5.29 s versus 5.36 s for the 745Le. The 0.07 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the C 400 e 4MATIC Saloon is doing 135 km/h against 141 km/h for the 745Le. The gap is 0.13 s. The gap remains stable from the start.

At 400 metres standing start, the 745Le crosses the line in 13.47 s versus 13.55 s. The 0.08 s gap represents roughly 4 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 745Le continues to build its lead. At 600 metres, it runs at 200 km/h versus 191 km/h. At 1,000 metres, the 745Le finishes in 23.97 s versus 24.53 s, with a 0.57 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.

What the numbers don’t tell you

The C 400 e 4MATIC Saloon features all-wheel drive (AWD) against the 745Le’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 745Le is capped at 250 (i.e. 155 mph - industry threshold) km/h, the C 400 e 4MATIC Saloon 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 (5.19 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 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
