IS 300 AWD vs Atto 3 Extended Range: chronicle of a drag race at 210 km/h
The launch: 0 to 100 km/h
Off the line, the Atto 3 Extended Range hits 100 km/h in 7.41 s versus 7.70 s for the IS 300 AWD. The instant torque of 310 Nm from the electric motor makes the difference. At this point, the Atto 3 Extended Range leads by 0.29 s and sits roughly 7 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Atto 3 Extended Range is doing 121 km/h against 122 km/h for the IS 300 AWD. The gap is 0.23 s. The gap remains stable from the start.
At 400 metres standing start, the Atto 3 Extended Range crosses the line in 15.57 s versus 15.66 s. The 0.09 s gap represents roughly 4 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Atto 3 Extended Range 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 0.15 s.
Around 486 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 29.19 s. The 1.44 s delta in favour of the IS 300 AWD shows that top speed makes a clear difference.
What the numbers don’t tell you
On paper, the IS 300 AWD combines 245 hp, 350 Nm and 1,735 kg — a clear theoretical edge over the Atto 3 Extended Range. Yet the Atto 3 Extended Range launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the Atto 3 Extended Range has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs — exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.
Both rivals are electronically governed, but not at the same level: the IS 300 AWD is capped at 210 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 0.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
BYD Atto 3 Extended Range is slightly faster than the Lexus IS 300 AWD to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
