The start: 0 to 100 km/h

Off the line, the Dolphin Boost 150kW hits 100 km/h in 6.93 s versus 7.54 s for the Megane E-Tech Electric 217. At this point, the Dolphin Boost 150kW leads by 0.61 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Dolphin Boost 150kW is doing 126 km/h against 124 km/h for the Megane E-Tech Electric 217. The gap is 0.40 s. The challenger starts to claw back ground.

At 400 metres standing start, the Dolphin Boost 150kW crosses the line in 15.13 s versus 15.61 s. The 0.48 s gap represents roughly 20 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Dolphin Boost 150kW continues to build its lead. At 600 metres, it runs at 160 km/h versus 160 km/h. At 1,000 metres, the Dolphin Boost 150kW finishes in 28.66 s versus 29.16 s, with a 0.51 s lead. Both vehicles have similar top speeds (160 vs 160 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the Megane E-Tech Electric 217 and the Dolphin Boost 150kW are governed to 160 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two electric powertrains, the difference comes down to power-to-weight ratio (7.80 kg/hp vs 7.30 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.36 seconds. The 0.61 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
