The start: 0 to 100 km/h

Off the line, the 218d xDrive hits 100 km/h in 9.04 s versus 12.34 s for the Dolphin Active 70kW. Despite lacking instant torque, 150 hp of power compensates. At this point, the 218d xDrive leads by 3.30 s and sits roughly 40 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 218d xDrive is doing 109 km/h against 101 km/h for the Dolphin Active 70kW. The gap is 1.80 s. The challenger starts to claw back ground.

At 400 metres standing start, the 218d xDrive crosses the line in 16.54 s versus 18.84 s. The 2.30 s gap represents roughly 77 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 218d xDrive continues to build its lead. At 600 metres, it runs at 151 km/h versus 136 km/h. At 1,000 metres, the 218d xDrive finishes in 30.52 s versus 34.35 s, with a 3.83 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 218d xDrive is capped at 211 km/h, the Dolphin Active 70kW at 150 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 21.36 seconds. The 3.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
