The start: 0 to 100 km/h

Off the line, the 320d hits 100 km/h in 6.83 s versus 6.93 s for the Dolphin Boost 150kW. Despite lacking instant torque, 190 hp of power compensates. The 0.10 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 320d is doing 120 km/h against 126 km/h for the Dolphin Boost 150kW. The gap is 0.43 s. The gap widens compared to the 0-100.

At 400 metres standing start, the 320d crosses the line in 14.95 s versus 15.13 s. The 0.18 s gap represents roughly 8 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 320d continues to build its lead. At 600 metres, it runs at 166 km/h versus 160 km/h. At 1,000 metres, the 320d finishes in 27.60 s versus 28.66 s, with a 1.06 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Dolphin Boost 150kW is capped at 160 km/h, the 320d at 240 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 11.30 seconds. The 0.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
