IS 300 RWD vs Atto 3 Extended Range: chronicle of a drag race at 225 km/h
The launch: 0 to 100 km/h
Off the line, the IS 300 RWD hits 100 km/h in 7.40 s versus 7.41 s for the Atto 3 Extended Range. Despite lacking instant torque, 245 hp of power compensates. The 0.01 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Atto 3 Extended Range is doing 121 km/h against 124 km/h for the IS 300 RWD. The gap is 0.08 s. The gap widens compared to the 0-100.
At 400 metres standing start, the IS 300 RWD crosses the line in 15.44 s versus 15.57 s. The 0.13 s gap represents roughly 5 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the IS 300 RWD continues to build its lead. At 600 metres, it runs at 173 km/h versus 160 km/h. At 1,000 metres, the IS 300 RWD finishes in 27.59 s versus 29.19 s, with a 1.60 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the IS 300 RWD is capped at 225 km/h, the Atto 3 Extended Range 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 11.71 seconds. The 0.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Lexus IS 300 RWD and BYD Atto 3 Extended Range are virtually tied to 100 km/h. The gap is under a tenth of a second — only the physics engine can settle it step by step.
