The start: 0 to 100 km/h

Off the line, the E 400 e 4MATIC hits 100 km/h in 5.31 s versus 6.93 s for the Dolphin Boost 150kW. At this point, the E 400 e 4MATIC leads by 1.63 s and sits roughly 23 m ahead.

From 100 km/h to 400 metres

At 200 metres, the E 400 e 4MATIC is doing 135 km/h against 126 km/h for the Dolphin Boost 150kW. The gap is 1.18 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 15.13 s. The 1.57 s gap represents roughly 66 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the E 400 e 4MATIC continues to build its lead. At 600 metres, it runs at 190 km/h versus 160 km/h. At 1,000 metres, the E 400 e 4MATIC finishes in 24.58 s versus 28.66 s, with a 4.08 s lead.

What the numbers don’t tell you

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 Dolphin Boost 150kW at 160 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.

With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (5.89 kg/hp vs 7.30 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.58 seconds. The 1.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
