BYD Han EV 200kW 2WD vs BYD Dolphin Boost 150kW: which is truly faster?

Off the line, the Dolphin Boost 150kW hits 100 km/h in 6.93 s versus 7.76 s for the Han EV 200kW 2WD. At this point, the Dolphin Boost 150kW leads by 0.83 s and sits roughly 11 m ahead.

At 200 metres, the Dolphin Boost 150kW is doing 126 km/h against 123 km/h for the Han EV 200kW 2WD. The gap is 0.53 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 15.74 s. The 0.61 s gap represents roughly 26 m of track - two to three car lengths.

Past 400 metres, the situation changes. The Dolphin Boost 150kW maxes out at 160 km/h while the Han EV 200kW 2WD keeps accelerating towards 180 km/h. At 600 metres, the gap has dropped to 0.50 s.

Around 818 metres, both vehicles are level. This is the inversion point: the Han EV 200kW 2WD overcomes its launch deficit thanks to a 20 km/h higher top speed.

At 1,000 metres, the Han EV 200kW 2WD finishes in 28.20 s versus 28.66 s. The 0.45 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the Han EV 200kW 2WD is capped at 180 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 electric powertrains, the difference comes down to power-to-weight ratio (7.76 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 11.56 seconds. The 0.83 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
