Off the line, the M340i xDrive hits 100 km/h in 4.32 s versus 5.29 s for the C 400 e 4MATIC Saloon. Despite lacking instant torque, 382 hp of power compensates. At this point, the M340i xDrive leads by 0.97 s and sits roughly 11 m ahead.
At 200 metres, the M340i xDrive is doing 147 km/h against 135 km/h for the C 400 e 4MATIC Saloon. The gap is 0.72 s. The challenger starts to claw back ground.
At 400 metres standing start, the M340i xDrive crosses the line in 12.46 s versus 13.55 s. The 1.09 s gap represents roughly 50 m of track - a gap visible to the naked eye.
Past 400 metres, the M340i xDrive continues to build its lead. At 600 metres, it runs at 206 km/h versus 191 km/h. At 1,000 metres, the M340i xDrive finishes in 22.65 s versus 24.53 s, with a 1.89 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the M340i xDrive 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.
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 0.97 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
