Audi A3 Sedan vs BYD Dolphin Boost 150kW: which is truly faster?

Off the line, the A3 Sedan hits 100 km/h in 6.21 s versus 6.93 s for the Dolphin Boost 150kW. Despite lacking instant torque, 204 hp of power compensates. At this point, the A3 Sedan leads by 0.72 s and sits roughly 21 m ahead.

At 200 metres, the A3 Sedan is doing 119 km/h against 126 km/h for the Dolphin Boost 150kW. The gap is 0.66 s. The gap remains stable from the start.

At 400 metres standing start, the A3 Sedan crosses the line in 14.73 s versus 15.13 s. The 0.40 s gap represents roughly 17 m of track - two to three car lengths.

Past 400 metres, the A3 Sedan continues to build its lead. At 600 metres, it runs at 169 km/h versus 160 km/h. At 1,000 metres, the A3 Sedan finishes in 27.19 s versus 28.66 s, with a 1.47 s lead.

Electronically capped at 160 km/h, the Dolphin Boost 150kW never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

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 11.24 seconds. The 0.72 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
