Off the line, the 540i hits 100 km/h in 5.06 s versus 5.29 s for the C 400 e 4MATIC Limousine. Despite lacking instant torque, 340 hp of power compensates. Despite the faster sprint time, the C 400 e 4MATIC Limousine is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 540i is doing 143 km/h against 135 km/h for the C 400 e 4MATIC Limousine. The gap is 0.09 s. The challenger starts to claw back ground.
At 400 metres standing start, the 540i crosses the line in 13.21 s versus 13.55 s. The 0.34 s gap represents roughly 16 m of track - two to three car lengths.
Past 400 metres, the 540i continues to build its lead. At 600 metres, it runs at 200 km/h versus 191 km/h. At 1,000 metres, the 540i finishes in 23.70 s versus 24.53 s, with a 0.84 s lead. Both vehicles have similar top speeds (240 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
The C 400 e 4MATIC Limousine features all-wheel drive (AWD) against the 540i’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 540i at 250 (i.e. 155 mph - industry threshold) 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 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 540i G30 wins (5,06 s vs 5,29 s).
