Off the line, the E 400 e 4MATIC hits 100 km/h in 5.31 s versus 7.75 s for the 420d Convertible. The instant torque of 650 Nm from the electric motor makes the difference. At this point, the E 400 e 4MATIC leads by 2.45 s and sits roughly 15 m ahead.
At 200 metres, the E 400 e 4MATIC is doing 135 km/h against 116 km/h for the 420d Convertible. The gap is 1.25 s. The challenger starts to claw back ground.
At 400 metres standing start, the E 400 e 4MATIC crosses the line in 13.57 s versus 15.64 s. The 2.07 s gap represents roughly 80 m of track - a gap visible to the naked eye.
Past 400 metres, the E 400 e 4MATIC continues to build its lead. At 600 metres, it runs at 190 km/h versus 161 km/h. At 1,000 metres, the E 400 e 4MATIC finishes in 24.58 s versus 28.69 s, with a 4.11 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 236 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the E 400 e 4MATIC is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 420d Convertible at 236 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 12.82 seconds. The 2.45 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, E 400 e 4MATIC W214 wins (5,30 s vs 7,75 s).
E 400 e 4MATIC W214 goes from 0 to 100 km/h in 5,30 seconds (calibrated simulation).
