The start: 0 to 100 km/h

Off the line, the 320e hits 100 km/h in 7.46 s versus 7.59 s for the E 220 d. The instant torque of 350 Nm from the electric motor makes the difference. At this point, the 320e leads by 0.13 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 320e is doing 115 km/h against 118 km/h for the E 220 d. The gap is 0.26 s. The gap widens compared to the 0-100.

At 400 metres standing start, the 320e crosses the line in 15.43 s versus 15.51 s. The 0.08 s gap represents roughly 3 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. The 320e maxes out at 215 km/h while the E 220 d keeps accelerating towards 236 km/h. At 600 metres, the gap has dropped to 0.13 s.

Around 477 metres, both vehicles are level. This is the inversion point: the E 220 d overcomes its launch deficit thanks to a 21 km/h higher top speed.

At 1,000 metres, the E 220 d finishes in 28.12 s versus 28.77 s. The 0.65 s delta in favour of the E 220 d shows that top speed makes a clear difference.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 320e is capped at 220 km/h, the E 220 d 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 12.74 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
