IS 300 AWD vs Dolphin Boost 150kW: chronicle of a drag race at 210 km/h
The launch: 0 to 100 km/h
Off the line, the Dolphin Boost 150kW hits 100 km/h in 6.93 s versus 7.70 s for the IS 300 AWD. The instant torque of 290 Nm from the electric motor makes the difference. At this point, the Dolphin Boost 150kW leads by 0.77 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 122 km/h for the IS 300 AWD. The gap is 0.45 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 15.66 s. The 0.52 s gap represents roughly 22 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Dolphin Boost 150kW maxes out at 160 km/h while the IS 300 AWD keeps accelerating towards 210 km/h. At 600 metres, the gap has dropped to 0.39 s.
Around 759 metres, both vehicles are level. This is the inversion point: the IS 300 AWD overcomes its launch deficit thanks to a 50 km/h higher top speed.
At 1,000 metres, the IS 300 AWD finishes in 27.75 s versus 28.66 s. The 0.91 s delta in favour of the IS 300 AWD shows that top speed makes a clear difference.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the IS 300 AWD is capped at 210 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.
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 11.57 seconds. The 0.77 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
BYD Dolphin Boost 150kW has a clear edge over the Lexus IS 300 AWD to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
